Garden Maintenance
Keep plants watered deeply but frequency may be reduced as temperatures fall.
Reduce frequency of irrigation to succulent trees such as willows in preparation for winter.
Fertilize citrus, fruit trees, roses, and lawns on Labor Day. This month is also good to fertilize warm-season succulents.
As night time temperatures go down seed your cool-season turf grasses.
Keep weeds under control--pull summer-season weeds before seeds are set.
What To Plant
Fall is the best time to plant trees and shrubs as roots grow well in our warm fall soil.
