Apples that stay on the tree longest are the most heavily infested by codling moths. Apples harvested early are the least infested. Populations of this pest increase with each generation produced.
Plants originally coming from a desert are watered less often than those that don’t come from deserts. This is because desert plants have methods of surviving a longer time between irrigations.
There are three reasons why sago palms are yellowing: their location, needed soil amendments and improper watering.
The SNWA offers a list of water-smart trees that are supposed to use less water than other types. But they still need to be managed.
