Ask A Desert Gardener, March 2025
March is a busy month as we prepare our landscapes for the Spring. In addition to applying first fertilizer treatment to the soil, resetting our irrigation systems, and removing winter damages, we may also be adding plants or planning a total overhaul of our landscapes and irrigation systems!
It is important to be knowledgeable about what you want and how to fulfill your goals.
Even though garden stores are carrying particular plants, it does NOT mean that these plants are appropriate or will even survive in your gardens. Numerous annuals, perennials and even succulents cannot survive temperatures falling below the 30s or above 100! Most fruit trees need a minimum of 6 hours of sun, but not direct afternoon sun! All vegetables, fruit trees, and many flowers cannot tolerate rock mulch surrounding their roots and stems in summer. Use organic mulch instead. Remember that Sago are NOT palm trees and Red Yuccas are NOT Yuccas and should not be exposed to long periods of direct summer sun.
No Palm tree is indigenous to Nevada so be sure that the palms you choose can adapt. They require significant amounts of water (NOT drought-tolerant) and are not exposed to very high or low temperatures. In addition, Fan Palms can be severely damaged by Nevada’s winds. Be wary of nurseries encouraging you to plant Queen Palms. Although these trees do well in Southern California, they are severely damaged by our temperatures since they prefer a more tropical climate!
Before modifying your landscapes, make sure that your HOA permits these additions. Do NOT plant cactus, yucca or agave near walkway areas where people or pets might get hurt. Do Not plant “messy” trees such as African Sumac, Mesquite or Pepper Trees near a pool or entrances since they are constantly dropping leaves and foliage.
Plan for the future. Small trees and bushes grow and what looks beautiful this season may grow into overcrowded specimens in the future. Look around your neighborhood and you will see palms growing above rooflines and Cypress Trees penetrating the eaves of houses!
Just remember: Plan before you plant!
