AZ Plant Lady House Call: Citrus, Herbs, Sun and Bare Walls

Oftentimes when I am called to help a homeowner with their landscape, they pose a problem and/or a question about a certain area in their landscape.

I will share a few with, you now and then, in the hopes that I can help those of you who may have a similar situation.

Okay, let’s first look at this resident’s sunny area…

Wanted to create a Southern European garden theme

As you can see, there is a young citrus tree growing in this corner bed.

The resident, who was from Europe, wanted to create a Southern European garden theme in her backyard.  However, in this area, she disliked the appearance of the bare wall around her citrus tree.  She wanted to have a retaining wall installed and raise the level of the bed and plant an assortment of herbs, which would cover part of the bare expanse of the wall.

The problem, is that you cannot raise the level of soil or you will suffocate the roots of the citrus tree.  Plants need the oxygen that is present in the soil.  Most of the oxygen is found in the upper levels of soil.  Adding more soil would decrease the amount of oxygen where the plant roots currently are located.

Taking out the citrus tree and replanting it into a raised bed was not an option in this case.

So, what would you do in this area?

Recommendation: Add three tall (3 feet or higher), colorful, glazed pots and place them up against the wall – one in the corner and the other two on either side.  Select pots in bright colors such as blue or orange, which will add a punch of color to the landscape AND plant an assortment of herbs in the pots.

Herbs are quite tough and can handle being in containers better then other flowering plants during the summer months and on through winter.

As the citrus tree grows and shades this spot more, the resident can switch out the sun-loving herbs for container plants that enjoy shady conditions.

So, what do you think of this solution? Do you have an area like this where you want to add color up against a bare wall?

I hope you enjoyed my first “AZ Plant Lady House Call”.  I will be posting more in the future in the hopes that I can help you with an issue you may be facing in your own garden.
