Cooler weather is coming and before you know it we will reach regular freezing temperatures. Just because it is time to put the garden hose away does not mean you can stop watering your plants. Although there may be fleeting blooms and leaves your trees, shrubs and perennials still require a sip of water every now and again.
A general rule of thumb would be to water your trees and shrubs about twice a week with the current temperatures we are seeing this late in October. As we progress into November and have colder temperatures that may be bumped down to once a week dependent upon conditions.
