newly-planted landscape

Have you ever driven by a newly-planted landscape?  If so, you probably noticed that many of the plants were quite small.  

I like to joke that sometimes you need a magnifying glass just to see the new plants. But as small as they are, within a short amount of time, those plants start to grow.  

overgrown plants are unattractive.

Look at the same landscape three years later. The plants are well-established and look great.  

Fast forward eight-ten years, and you may start to see signs of some plants becoming overgrown and unattractive.

When this happens to shrubs, we can often push a ‘restart button’ (for most types of shrubs) and prune them back severely in spring using a good pair of loppers, which reduces their size. I use my Corona loppers to do major pruning of my shrubs.

However, there are some plants where this approach doesn’t work.

Let’s identify a few of these plants and how to deal with them once they outgrow their allotted space or become filled with old, woody growth.

Desert Spoon (Dasylirion wheeleri)

Desert Spoon (Dasylirion wheeleri)

Desert spoon is one of my favorite plants.  I love how its blue-gray, spiky leaves add texture to the garden and contrast with plants that have darker green foliage.  

Old, Overgrown Plants

After ten years or more in the landscape, desert spoon can start to take on a ragged, rather unattractive appearance, as well as grow quite large.

When this happens, I recommend that they be removed and a new one planted in its place.  

Now, some of you may think that may seem wasteful, but I invite you to take another look at your landscape and the plants within it.

Your outdoor space isn’t static and unchanging. Its appearance changes with the seasons with plants blooming at different times. Trees gradually extend the amount of shade they provide and plants change in size.  

A newly planted garden doesn’t look the same through the years, it changes.  

Trailing Rosemary (Rosmarinus officinalis 'Prostratus')

Trailing Rosemary (Rosmarinus officinalis ‘Prostratus’)

Rosemary is a good choice for those who want rich, dark green color in the garden. Bees love the light blue flowers that appear in late winter and spring, and the aromatic foliage can be used to flavor your favorite dishes.  

Old, Overgrown Plants

But, as time passes, it does get bigger, outgrowing its original space.  

Old, Overgrown Plants

When this happens, people start to shear their rosemary, which is stressful for the plant and contributes to sections of branches dying.

For those who don’t like the formal look, pruning rosemary back severely would be your first impulse. But, the problem with rosemary is that they don’t respond well to severe pruning.

So again, in this case, it’s best to pull out the old rosemary and add a new one, which will provide beauty for several years.

To avoid having to remove and replace rosemary too often, allow them plenty of room to grow to their mature size.

Red Yucca (Hesperaloe parviflora)

Red Yucca (Hesperaloe parviflora)

Red yucca is prized for its succulent, green leaves that resemble an ornamental grass and its coral flowers, which appear spring through fall.

red yucca Overgrown Plant

Once it has been growing seven years or more, red yucca may overwhelm the landscape visually. This is particularly true if the area it’s growing in isn’t very big.

Occasionally, some people will try to remove the outer leaves at the base. However, this is laborious and only serves to stimulate red yucca to grow back faster.

In those situations, I tell people that their plant has had a nice life, but it’s time to start over.

Newly-planted red yucca

You may be thinking, why use plants that you’ll only have to replace after seven to ten years?

Well, all three of these plants add beauty to the landscape and are low-maintenance.

Another way to think of it is to compare your landscape with the interior of your home.  Do you make small changes to the decor of your home every few years to keep it looking fresh and attractive? The same should be true of the outside.

Replacing a few plants after seven years or more isn’t expensive. Don’t you think that the beauty these plants offer to your outdoor space makes them worth it?

What have you replaced in your garden recently?

A Glimpse into Phoenix Homesteads District

Phoenix’s Only Adobe Neighborhood

The Phoenix Homesteads District dates back to the 1930s and is the only adobe neighborhood in Phoenix.  Mature pine trees line the streets. They are interspersed with Mexican fan palms. This creates a green tunnel that beckons you to explore further.

Small adobe homes sit on large lots with large, mature trees and shrubs.

Small Adobe Homes and Bountiful Gardens

Within this district, you’ll find small adobe homes nestled on spacious lots, adorned with towering trees and lush shrubs. These homes, constructed in the ’30s and ’40s, are designed to facilitate food cultivation and small-scale livestock ownership.

An Artistic Garden Gem

The purpose of my journey to this historic neighborhood was to visit a local artist and her picturesque gardens. 

This historic garden jewel is located on ‘Flower Street.’

Choosing the Right New Plants for Your Garden

Research New Plants Before You Shop

New plants can be planted in the fall with ease. You may notice the lengthening shadows on your way home from work, signaling shorter days. Or maybe you’ve noticed that you aren’t rushing indoors as quickly as you did earlier this summer.

It is time for cleaning up the summer garden and replanting new plants in the fall.

beautiful colors of fall planting new plants

Fall is a time to celebrate the end of hot summer temperatures and what better way to do that than to venture out into the garden again?

Before you rush off to the nursery to shop for new plants, it’s essential to choose the right ones to ensure their successful growth in your garden. Researching your plant choices is the key to avoiding disappointment and wasted resources.

Here are three vital questions to answer before you start planting:

1. What Will Be the Mature Size of Your Plant?

It’s crucial to know how large your plant will grow once it reaches maturity. Neglecting this aspect can lead to overcrowded and overgrown landscapes. Small nursery plants can quickly transform into giants in your garden, potentially overwhelming your outdoor space.

This homeowner had ficus trees planted in the raised bed around their swimming pool.

Now, when you look at this picture, you may be wondering why would anyone plant ficus trees in this area.

 Newly planted ficus tree

 Well, it goes without saying that new plants are much smaller than they will be once they are planted and have a chance to grow.

Mature ficus tree

But, once plants are in the ground and begin growing, that small little plant can increase in size exponentially.  In this case, the ficus looks like it is ready to swallow up this house.

Over-planted shrubs calls for a new plant plan

Over-planted shrubs

Another example of not researching the mature size of plants can be seen in many landscapes throughout the Southwest.

In a nutshell, the small 1 foot tall and wide shrub in the nursery can grow more than 10X its original size.  

2. What Is the Preferred Sun Exposure for Your Plant?

Understanding the ideal sun exposure for your chosen plants is essential for their health and development. Placing sun-loving plants in the shade or shade-loving ones in full sun can result in leggy growth, fewer leaves, and diminished flowering.

What a plant that does best in filtered shade looks like when planted in full sun.

Conversely, if you place a plant that does best in the filtered shade in an area that gets full, afternoon sun – it will suffer.  

You will save yourself a lot of time, money and frustration by simply placing plants in the exposure they like.  

3. What Maintenance Does Your Plant Require?

Fuss-free Eremophila ‘Summertime Blue’

Different plants have varying maintenance needs. Some demand frequent pruning, fertilizing, and protection from pests, while others thrive with minimal attention. Choose plants that align with your preferred level of maintenance, and consider native or adapted species for fuss-free gardening.

Some plants need frequent pruning, fertilizing and protection from pests.

Others are what I like to call ‘fuss-free’ and need little else besides water.

The amount of maintenance a plant needs is largely dependent on whether or not it is native or adapted to your client.

queen palms that are dying

For example in the Phoenix area where I live, queen palms are very popular.  The problem is, is that they are not particularly well-adapted to our desert climate.

In fact, it is rare to see a healthy queen palm growing in the greater Phoenix area.  Frequent applications of palm fertilizer are required to get them to look okay and even then, they will never look as good as those growing in Florida or California.

I don’t like to fuss over plants except for a couple of rose bushes in my garden, so I am a strong proponent of using native or adapted plants that need little pruning, no fertilizer and aren’t bothered by insect pests.

Now we know three important questions to get answered before selecting new plants for your garden.

Where Can You Go for Local Answers to These Questions?

To find answers to these questions and more, consult resources such as master gardeners, local botanical gardens, and online gardening communities. Armed with knowledge, you can make informed choices when selecting new plants for your garden, ensuring a beautiful and thriving landscape.

Master gardeners are an invaluable resource and their job is to help people learn how to grow new plants successfully. You can call them, email your questions or stop by and talk to them in person.

Take some time to visit your local botanical garden. Write down which plants you like, or snap a photo of them with your phone. Note how large they are and what type of exposure they are growing in.  

3 Tips for Fall Planting Success

It may surprise you to find that it is easier to find plants that thrive in the sun than in the shade.

Especially if you live in the desert Southwest. Why is this, you may ask?

Well, it can be hard to find plants that can handle the intense, dry heat of our climate while flourishing in the shade. While there are a number of lovely plants that can work in shady conditions, it’s hard to know which ones will, which is why I make sure to include my favorites for students in my online gardening class.

So, what do you do if you have a shady spot to fill?

Yellow Dot (Wedolia trilobata)

One of my favorites is Yellow Dot (Wedolia trilobata), which is a vining ground cover with lush, dark green leaves interspersed with yellow daisy-like flowers.

Here is a plant that does fabulously in dark shade and will handle brief periods of full sun. 

Yellow Dot grows quickly to 1 ft. high and 4 – 6 ft. wide and is hardy to 30 degrees. It’s susceptible to frost damage, which can be easily pruned back in spring.

One of my favorite characteristics of this lush green ground cover is that it has a long bloom period – spring through fall. 

It grows beautifully underneath trees, along pathways, and among boulders. You just want to be sure to allow enough room for them to spread.

So, if you have a difficult shady spot that needs a plant – try Yellow Dot.

How about you?  Do you have a favorite plant that does well in shady spots?  I’d love to hear about it!

Gardening in the Desert Southwest – Interview

Understanding Garden Color Blindness

Last month, I diagnosed my first ever case of garden color blindness.

Now, I realize that I am no doctor or medical authority. However, as a horticulturist, I am somewhat of an expert in the garden, which is where I made my diagnosis.

Appreciating the Beauty of Drought-Tolerant Landscapes in the Southwest

Before I tell you more about my unorthodox diagnosis, I invite you to look at this photo. It’s of a lovely low-desert landscape filled with a mixture of trees, shrubs, and cacti.

Here is another lovely desert landscape with succulents, vines, and a flowering Parry’s Penstemon.

My client has a garden much like those photographed above. It’s filled with a variety of flowering shrubs, agaves, cacti, and ground covers.

Don’t Worry; Everything is Going to Be Okay

So when he called me in a panic telling me that the plants in his garden were doing poorly, I came ready to help him out.

However, once I got there, I didn’t see any problems. His plants looked great! He told me that his plants did look fine before he left on vacation. But, when he returned, they seemed less green and somewhat sickly.

It took me a while to assure him that his garden was healthy, and then we made small talk and I asked him where he went on vacation. His answer? Michigan!

That was an AH-HA moment! I now knew what the problem was, and it wasn’t with his plants. It was his eyes and his perception of green.

Let me illustrate:

Michigan is one of my favorite states to visit because my oldest daughter lives there with her family.

It is a beautiful place to explore with lovely gardens.

There are stunning botanical gardens awash with vibrant flowers spring through summer along with vivid greens.

A northern garden

Visiting Michigan in summer is something that I look forward to every year. The gardens with their lush greens are a soothing balm when I’m tired of the hot, dry summer heat back home.

My client had an experience much like this, enjoying the saturated greens of a Midwest summer before he returned home to his garden.

Now, take another look at the desert landscapes below:

Color Blindness in the Garden
Color Blindness in the Garden

Do they look a little less colorful to you? Dare I say drab? 

When we travel to regions outside of the desert, our eyes become accustomed to bright, saturated colors that are part of that landscape. Then, when we return home, the soft, subtle shades of green are less evident to us due to the ‘green overload’ we are returning from.

It is Only Temporary Color Blindness

As I explained this to my client, he finally understood that there was nothing wrong with his plants, just his eyes.

The good news is that this is temporary color blindness and that his garden will soon look as beautiful and vibrant as it did before he went on vacation.

Have you ever suffered from temporary color blindness in the garden?

container plants

Exploring Unconventional Container Plants

What type of plants comes to mind when you are planning what to plant in your containers?

I’m willing to bet that purple hopbush (Dodonaea viscosa ‘Purpurea’) and bush morning glory (Convolvulus cneorum) probably weren’t the first plants that came to mind.

Thinking Beyond the Blooms

Admittedly, I tend to think of using plants known for their flowers or succulents in my containers.  That is until a trip to California that I took this past April.

A Visit to Cornerstone Sonoma

In the picturesque Napa Valley region of northern California, sits Cornerstone Sonoma, which describes itself as “a wine country marketplace featuring a collection of world-class shopping, boutique wine rooms, artisanal foods, art-inspired gardens.”

Believe me; it is all that and more.

Amidst all its offerings, it was the unconventional container plantings that captured my attention.

Unusual Choices in Container Plants

Purple hopbush (Dodonaea viscosa ‘Purpurea’), shrubby germander (Teucrium fruiticans), and violas.

Intriguingly, I discovered square steel containers filled with plants celebrated for their foliage, a departure from the typical container plantings I was accustomed to.

These unique designs were creative and beautiful.

container plants

The Appeal of Foliage-Focused Container Plantings

There were quite a few things about this type of container planting that appealed to me.

One, it is low-maintenance – no deadheading required.  Just some light pruning 2 – 3 times a year, to control their size. Second, the plants are all drought tolerant (with the exception of the violas). Lastly, I like seeing new ways of doing things and using plants prized for their foliage in containers is something we don’t see too often.  

Replicating the Concept with Container Plants at Home

Fast forward a few months, and I decided to rethink what to add to the large, blue planter by my front entry.  So, I thought, why not try the same arrangement?

Smaller but Promising

container plants

Granted, the plants are smaller than those I saw in California, but given a few months, they should grow in nicely.

As you can see my new plants are rather mall, however, the purple hopbush will grow taller and its evergreen foliage will add shades of purple and green to this space. Furthermore, this shrub is one of those highly-prized plants that do well in both sun and filtered shade.

Embracing Foliage Diversity

The silvery-gray foliage of bush morning glory creates a great color contrast with the darker greens of the other plants. While it may not flower much in this semi-shady corner, I want it for its silvery foliage.

Adding Greenery to the Mix

In addition, I want to use a plant that has bright green foliage, so I have a single foxtail asparagus fern (Asparagus densiflorus Myers), which will thrive in this semi-shady exposure. 

Maintenance will be relatively simple with periodic pruning to keep wayward branches in check. Fertilizing in spring and late summer with a slow-release fertilizer such as Osmocote will be all that’s needed to keep my container plants happy.

Do you have any plants with attractive foliage that you would use in containers? 

From Trash to Treasure: Unique, Fuss-Free Container Plantings

I have a confession to make.  

I don’t have any containers filled with flowering annuals. Shocking isn’t it?

There are a few reasons for this, the most important one is that I prefer using relatively fuss-free plants that look great all year in my pots.  

I don’t have much patience for high-maintenance containers. In particular, ones with flowering annuals that need frequent irrigation. Not to mention deadheading of spent flowers and having to change them out seasonally. But, I do love the way they look.

container-red-geraniums

Red Geraniums and White Bacopa

My inclination to avoid flowering annuals in my own garden has to do with my past and no, it’s nothing scandalous.

It does have to do with my work in the past. For five years, I was in charge of 45 pots. Each container was always be filled with colorful flowers.

Believe me, keeping all of those pots looking beautiful was a lot of work! Countless trips to the nursery, fertilizing, watering and replacing them twice a year got tiresome. Not to mention that I broke my foot when I tripping on a curb, while loading flats of flowers. 

So, it may not come as a surprise that I prefer using succulent plants in my pots.

Preparing Your Garden for a Heatwave: 5 Essential Tips

Have you ever wondered how your plants fare in the scorching heat of summer? Is your garden equipped to withstand the punishing temperatures that a heatwave can bring, whether you reside in the arid desert Southwest or more temperate regions? In this guide, we’ll explore how to create a heatproof garden that thrives even during the hottest days of summer.

What do your plants look like in the middle of summer?  Do they thrive despite the hot temperatures?  

Or do they look more like this?

Heatproof Gardening tips

Assessing Your Garden’s Heat Tolerance

Before we dive into our tips for heatproofing your garden, it’s crucial to understand how to recognize the signs of heat stress in your plants. During the hottest part of the day, take a stroll through your garden and keep an eye out for wilting leaves, as well as leaves turning yellow or brown – all telltale signs of heat stress.

5 Key Strategies to Heatproof Your Garden

Here are five essential strategies to help your garden not only survive but thrive in the face of scorching summer temperatures:

1. Embrace Native and Climate-Adapted Plants

Heatproof Gardening tips

Selecting native or climate-adapted plants is a foundational step in creating an attractive, low-maintenance landscape that remains beautiful year-round. These plants possess unique characteristics that enable them to withstand local climate conditions, including extreme summer heat. Learn how plants like Langman’s Sage and Mexican Honeysuckle adapt to thrive in the heat.

All too often, we find ourselves with landscapes filled with plants. These plants often have large leaves and struggle to survive the hot, summer months.  This results in unattractive plants that we work hard to help sustain them until cooler temperatures arrive. Usually, these plants are best meant to grow in climates with less extreme heat.

Plants Adapt to Change

Langman's Sage (Leucophyllum langmaniae)

Langman’s Sage (Leucophyllum langmaniae)

Let’s look at an example of an adaptation that this Langman’s sage. The adaptation enables it to handle full sun and 110+ temperatures without undue stress.

Notice that the flowers have small hairs.  So do the leaves, giving them a slightly grayish cast.  These tiny hairs help to reflect the sun’s rays, which lowers the temperature of the leaves and flowers.

Mexican Honeysuckle (Justicia spicigera) and Shrubby Germander 'Azurea' (Teucrium fruticans 'Azurea')

Mexican Honeysuckle (Justicia spicigera) and Shrubby Germander ‘Azurea’ (Teucrium fruticans ‘Azurea’)

Small Leaves Help

Another way that plants have to handle the heat is by having small leaves. This limits the amount of water lost, which helps them to deal with hot, dry temperatures.

Here in the desert Southwest, there are many native plants that are used. There are also plants from Australia and other arid regions, which have similar climates.

2. Harness the Power of Shade

Heatproof Gardening tips

Introducing shade into your garden offers respite from the relentless sun, benefiting both plants and your home’s overall cooling. Discover how to provide just the right amount of shade by strategically planting trees that offer filtered shade. This allows enough sunlight for other plants to flourish.

3. Master the Art of Deep and Infrequent Watering

Heatproof Gardening tips

Plants need water to survive, and not surprisingly, they need the most in the summer.  However, we often water them too often and shallowly for it to do much good.

Shallow watering keeps roots close to the surface of the soil. There the soil temperatures are hot and the water dries up quickly.

Deep Watering is the Rule

Water is essential for your plants, especially during summer, but not all watering methods are created equal. Learn why deep watering, encouraging deep root growth, is far more effective than shallow watering. Discover how to gauge the depth of your watering and why early morning is the best time to hydrate your plants.

“Plants that are watered deeply and infrequently are better able to withstand the heat.”

Shrubs should be watered to a depth of 2 feet and perennials and groundcovers to 18 inches.  You can determine how deeply you are watering by inserting a piece of rebar down into the soil (right after you have finished watering) to see how long you need to irrigate.  On average, 2 hours is the length of time to irrigate to the desired depth.  

An Online Course to Help You Understand Desert Garden Needs

In my online class, Desert Gardening 101, I teach my students that watering deeply is as important as the time of day that you water. The best time to water is early in the morning.  Watering plants in the afternoon is not as useful since plants allocate their resources at that time toward surviving the stresses of the heat and so they do not take up water as efficiently.  

4. Mulch for Cooler Soil and Moisture Conservation

Heatproof Gardening tips

Mulch plays a crucial role in heatproofing your garden. It helps regulate soil temperatures, keeping them cooler during the summer while conserving moisture – essential for plant health. Explore unconventional mulch options, including fallen leaves, pine needles, and even fallen flowers, and learn how they can enhance your garden’s well-being.

A bonus is that they also help to prevent weeds from taking root.

Heatproof Gardening tips

Be Creative with Mulch Components

Let’s take a minute to rethink our definition of what makes an excellent mulch.  

While shredded bark and wood chips may come to mind, did you know that fallen leaves, pine needles, and even fallen flowers can also serve as a mulch?  That is how nature does it.

Be Cautious with the Leaf Blower

So, the next time you are tempted to whip out your leaf blower, how about directing it toward the base of your plants where the leaves and flowers can serve as a mulch?

They will also help to improve the soil around your plants as they decay.

5. Opt for Succulents and Heat-Tolerant Shrubs in Containers

Gardening tips

Tip for Heatproof Garden

While growing pretty flowers in containers is relatively simple in fall, winter and spring-summer can be another matter entirely.  Often, it can be hard to grow flowering annuals in pots throughout the hot summer.

The reason for this is that the soil around the roots of container plants is hotter than if grown in the ground.

Critical Top Soil

This is especially true for the outer 6 inches of soil which heats up in response to air temperatures and the hot container.  As a result, annuals can wilt and struggle to produce flowers in summer.

Succulents are a great way to enjoy attractive container plantings throughout the year, not just in summer.  Their ability to store water is what makes them an excellent choice for containers.

Gardening tips

Tip for Heatproof Garden

If you want to grow something else besides succulents, how about trying heat-tolerant shrubs? Bougainvillea does great in pots as does lantana.

Gardening tips

Tip for Heatproof Garden

Caring for Heat-Stressed Plants

Another tip for containers is to leave them empty in the summer months and wait until fall to plant them.  

When thinking in terms of growing plants in containers in hot climates, bigger is better – at least 2 feet wide at the top.  The larger the pot, the more soil and therefore, more insulation for the roots from the hot outer zone.

So what can you do if you do have plants that are struggling in the heat – particularly during a heatwave?  

Other than replacing them, you can provide them with temporary shade such as a patio chair strategically placed so that it protects it against the afternoon sun. A light spraying of water over the plant and surrounding area in the evening can help reduce the temperature – don’t do this when the sun is out, or you may burn the foliage.

How to Help Your Plants Survive a Heatwave

“How much water do my plants need?”

I am often asked this question by desert dwellers and my answer is always, “That depends.”

desert-landscape

There are several variables that determine how much water plants need, along with the frequency of watering.

Variables include:

  • Type of soil (clay, sand, combination)
  • What kind of plant (native plants, higher water use flowering shrubs and ground covers, succulents, etc.)
  • Recommended depth of water
  • Desert region (low-desert, mid-altitude, high desert)
  • Efficiency of irrigation system
  • Water pressure (can vary between neighborhoods)

As you can see, there is no universal watering guideline in regards to how long to water or how often.

Let’s look into the variables a little more closely to help you determine what yours are:

Soil – Clay soils hold onto water longer than sandy soil. They take longer for water to permeate to the recommended depth. The result? Clay soils need irrigation less often than sandy ones but need to be watered for a longer length of time. Phoenix area soil tends to have more clay in them while those in the Palm Springs area are sandy.

Plants – Native or desert-adapted plants need less frequent irrigation versus those that come from tropical climates. Cacti and other succulents do well with infrequent irrigation.

Water Depth – Trees need to be watered deeply while ground covers and succulents do fine at a more shallow depth – shrubs fall in between the two.

Desert Region – Where you live in the desert matters when it comes to water and your plants. The differences include rainfall amounts, when the rain falls, high and low temps, and more. Residents of low-desert cities like Palm Springs and Phoenix need to add water to their plants more often than those who live in higher elevation regions such as Tucson.

Irrigation System – The older your irrigation system, the less efficient it is. This is due to mineral build-up within the system, which affects the amount of water that comes out. Also, old drip irrigation systems tend to accumulate leaks. The average lifespan for a drip irrigation system is 10-15 years. 

Despite these differences, what is a shared characteristic is that the vast majority of desert residents water too often and not deeply enough. This is usually due to lack of knowledge and thinking the ‘more is better,’ especially in the desert.

Landscapers are generally not a reliable source when it comes to scheduling irrigation – most recommend irrigating far too often.

So what is a desert dweller to do?

Thankfully, there is very useful information available for homeowners to help them figure out when and how much water their landscape needs.

Major metropolitan areas throughout the Southwest have excellent watering guidelines available for residents. The guidelines include the regional variables we have discussed so far.

Phoenix

Tucson

Watering guidelines are just that – guidelines. Circumstances may mean that you need to water more or less often, but these guides are a useful baseline to work from.

*One final note – before you implement a new irrigation schedule, it’s important to gradually wean your plants to the new one over several weeks. The reason for this is that it allows plants to become accustomed to the new schedule.

Yes, it does take a little work to figure out how much and often to water your plants, but these guides are incredibly helpful and will guide you along the way.

Citrus Trees Dropping Tiny, Green Fruit

The Joy of Growing Citrus Trees

Do you have a citrus trees in your garden? I do.

I have two trees – a Meyer lemon and a brand new ‘Trovita’ orange tree. I use the citrus in all kinds of fun ways and the trees have become a family pleasure.

Nostalgic Citrus Memories

As a child in California, we always had citrus trees in our backyard.  I would pick lemons from my favorite tree just off the back patio. Later, we moved to a larger ranch-style home that had several citrus. I honestly never paid much attention to them, because as a teenager I had more important things to think about – like boys and how to get perfect-perm for my hair (it was the 80’s).

Embracing Citrus Trees After the Bloom

Now as an adult (with permed hair thankfully in my past), I do pay attention to my trees. Consequently, I look forward to the fragrant blossoms that cover citrus trees in mid-winter.

As the blooms fade, tiny green fruit is left behind, which are baby citrus fruit. When spring progresses, some of the small, green fruit drop to the ground. Not surprisingly, this concerns gardeners who don’t understand why.

Understanding Citrus Tree Behavior

The Natural Process of Citrus Fruit Drop

Well, let me put all your worries to rest. This is a normal occurrence and not a citrus disease. Citrus trees produce more blossoms than it can grow into mature fruit. They do this in order to attract the most pollinators and after the flower petals drop, little green fruit is left behind, which ideally grow into large delicious fruit ready to harvest in winter. However, the tree cannot support that much fruit, so the tree figures out how much fruit it can grow to maturity and then drops the rest.

Managing Expectations with Young Trees

For those of you who have young citrus trees, I want to warn you that most of the little green fruit will drop. Citrus tree need a large root system and a lot of leaves to support a good amount of fruit and that only comes with age. So, if you see tiny, green citrus on the ground every spring – don’t panic. It is all part of the normal cycle of growing citrus.
