April Newsletter | Things to do now…
———————————————-

– Now is the last time for pruning most evergreen trees and shrubs.
– This is also the last chance to prune citrus and ficus and other sun-sensitive trees. Be careful. If you wait too long, new foliage will not have time to fill in before sun damage occurs. As a rule, any area of bark exposed to direct sun for 3 or 4 hours needs to be protected with shade cloth or tree wrap to prevent sunscald.
– Thrips begin to appear in Citrus Bloom. Don’t get alarmed at all those thrips crawling in and around your citrus blossoms. The citrus bloom is the most likely place to see thrips. Thrips vary in color from black to pale yellow. Since they pose no particular threat to citrus bloom, attempts to control them during the blooming season should be avoided to protect the honeybees.
– There are two general rules for pruning flowering trees and shrubs: For plants that produce blooms on old wood or last season’s growth, prune as soon as possible after the bloom ends. For flowering plants that produce blooms on new wood or this season’s growth, prune in late winter or early spring.
– Still time for fertilizing all trees, especially citrus deep fertilizing.
– It’s also a good time to apply a 2-3 inch layer of mulch around the base of trees and shrubs. This relatively inexpensive soil amendment does more to improve growing conditions around desert plants than any other treatment including fertilization. It reduces soil temperatures, runoff and evaporation, encourages nitrogen cycling and improves soil microbiology.
– Cut out any cold damage on tender plants as they begin to show new growth. That will be a good indication of where to cut.

Wait until nights are in the 60 degree range to start sowing seed for summer grasses. If there is a winter grass planted over existing Bermuda grass, discourage the winter grass by cutting it short and allowing it to dry out before resuming water to summer lawn grass. Grow Land specializes in winter-to-summer transitions, so call us for pricing!
