Water your palo verde trees (Parkinsonia spp., Zones 9–11). These desert beauties love the summer sun and thrive in the heat, but don’t neglect them when it’s time for a good, deep watering. Be sure to save the pruning for the winter months.
Keep grasshoppers at bay. These pests can be extremely invasive, so keep an eye on your plant leaves. If you find that you have a grasshopper problem, use an organic deterrent to keep them under control. Espoma Organic Insect Soap is a good choice if the grasshoppers have taken over. Also, you can make a natural, homemade garlic spray to deter the grasshoppers. Combine one part crushed garlic to three parts water, and spray the areas where you’re seeing activity.
Replace a tired, sun-loving plant. The amazing texture of the gopher plant (Euphorbia rigida, Zones 7–10), with its silver-green leaves and chartreuse flowers in the spring, makes it a fun choice.
