Trees
Watering: Place a hose near the root ball for 25-30 minutes on a slow trickle every other day during normal conditions. Water more often in warmer temperatures and if leaves start to show sign of wilting. Use caution with evergreens (needle and broad leaf) or if you have clay soil, make sure not to over water and drown your tree.
Shrubs
Watering: Soak root ball for 30 seconds to a minute, depending on the size of the plant. Do this every other day during hot, dry conditions. During cool or wet periods use your best judgment on watering.
Perennials
Watering: Water for 15-30 seconds as often as necessary. During hot dry conditions watering may be required twice daily, however during normal conditions once daily is sufficient.
Annuals
Watering: Water for 15-30 seconds as often as is necessary, a sprinkler will also work. During hot dry conditions watering may be required twice daily, however under normal conditions once per day is sufficient.
