Watering with a Sprinkler on a Hose in Sandy to Sandy Loam Soils

This is where you take a small hose like the one pictured, attach it to a hose and place it at the base of where you want to water the tree/shrub. For sand to sandy-loam soils, the soil feels coarse and seems that it can never suck up enough water. The following chart based on daytime temperature will help give you a guide on how often and long to run a small sprinkler on a hose. The wind is another factor that can change things.  When in doubt, you need to dig down 8 inches for shrubs/perennials and 12 inches for trees with a shovel, trowel or use a soil probe to make sure you are soaking in deep enough.

-50˚F or less once a month for evergreens; check every two months for deciduous plants during the dormant season and deep soak for one to two hours.
-50 to 70˚F deep soak once every two weeks after leaves emerge for one to two hours.
-70 to 85˚F deep soak once a week for one hour.
-85 to 95˚F deep soak twice a week for two hours.
-Above 95˚F, soak three times a week for two hours.

Add one extra water interval per windy day over 85 degrees F with wind speeds over 20 miles per hour.
