Not so true for some native and drought tolerant plant materials and shrubs. As you probably already know, installing drought tolerant and native plants and shrubs during the hot summer months is not the best idea for the shrubs or for your pocketbook. The hot days and warm nights combine to create a continual evaporational effect to the soil and creates a interesting challenge for the home gardener and professional alike who want only for those shrubs to flourish and display beauty within the landscape. The best time normally to install drought tolerant shrubs and native plant materials is in the fall and spring when the weather conditions are not as extreme and the newly planted shrubs roots can enjoy stretching out underground in the warm through the day and cool in the night soil temps. During the hot summer days evapotranspiration takes place which draws the available water from the soil into the air. Plus, gravity is doing it's thing and drawing water down words away from the root zone of the newly installed plant or shrubs causing extra stress on the establishment of the root system and the proper hydration of the shrubs in order for it to survive.
Native shrubs ( At least those here in Southern California ) get most of their supplemental water during the fall and spring months. By installing native shrubs in the middle of the year you are actually reversing a natural growing process the native shrubs are born to perform. The plant stresses out from not enough water at the root zone because of gravity and evapotranspiration and it also stress out from its roots being saturated with water it "Normally" does not receive during the hot summer months so what do you get ? A HEADACHE and FRUSTRATION.
Some "Sage Watering Advice" from our friends over at Tree of Life Nursery ( www.californianativeplants.com ) will help you during these hot summer days.
* Pre-irrigate the planting hole so there is adequate moisture around the root system.
*Apply 1-2 inches of organic mulch ( No Manure ) around the root zone of the plants but keep the mulch and excess soil well away from the stems and crown.
* Water by hose,drip,or low volume sprinkler in the early morning and avoid watering in the heat of the day or night.
* Water only when the soil in the root zone ( 6-8" down ) begins to dry out.
* For best results, avoid using overhead irrigation for long durations ( Especially in the sun ) because prolonged leaf wetting during the dry season can promote disease.
By understanding the ideal planting times for natives and drought tolerant plants and shrubs plus incorporating thoughtful and effecting watering habits to newly installed and existing plants materials, you will have better success and less stress and money loss from over watering or under watering your landscape kids.
