Citrus Trees: Do not fertilize this tree for the first year. After one year, apply ammonium sulfate three to four times per year (Feb., May, and August). Apply in accordance with the manufacturer recommendation. These trees should be deep watered and then allowed to dry out before being watered again. (Once per week is a general guide) Consult nursery professional for best type of citrus fertilizer for your needs.
Queen Palms: Queen Palms, unlike Mexican fan palms, require special care. Queen palms also need to be watered more often than other palms. You’ll need to fertilize your Queen palm with 1/4 cup of ammonium sulfate once per month, palm tree food every 90 days. All palms need some type fertilization care. See a nursery professional for proper fertilizers.
Desert Trees: Desert trees are native to this area and do not require any fertilization. Your drip emitters will be close to the root ball of the tree when first installed and should be pulled away as the tree matures to approximately one half the diameter of the canopy. This will help prevent the tree from blowing over and assist in developing a healthier root system. Once the tree is established you should eliminate the drip system to the tree and water deeply with the hose two (2) times per month.
Non Desert Trees: Non desert trees such as citrus, Ficus, Elms, and palms (just to name a few) prefer additional water. These trees will require more fertilizers and generally do better when planted as a young tree (15 gal. or smaller) vs. a mature specimen, which will have a hard time with acclimation.
Shrub Care: Desert shrubs require no fertilization. Non desert shrubs require fertilization twice per year with ammonium sulfate or a general fertilizer (16-8-4), once in the spring and once in the fall.
Cactus: Cacti need good drainage away from the roots and do not require any fertilizer. Water 2-3 times per month.
Ocotillos: This type of plant requires small amounts of water and takes up to three years to produce any signs of life. Water your ocotillo during dry periods with a garden hose to maintain a healthy look. You can also sprinkle the sides of the Ocotillo to assist in leafing out. Do this in the evening. We also recommend using a root stimulator on your Ocotillo when initially planted for a few months to encourage growth.
For good long and short term care of your landscape you should take the time to see to your trees’ and plants’ needs. Even low maintenance yards need some extra care a few times per year. A good fertilization and
watering schedule will produce an absolutely beautiful yard.
