Answer: In low desert conditions, it's important to make sure that the soil is consistently moist (not wet) so that the plant isn't stressed for water. Use a 2-3 inch layer of mulch to help maintain soil moisture. Water slowly and deeply to a depth of about 12 inches for mature plants. Since your plants are green and healthy, it sounds as if the soil has sufficient nitrogen. You might want to scratch a phosphorous source into the soil to the side of the plants. Bone meal is an organic source of phosphorous. I hope this helps!
