Watering is only needed when first installed or during extended periods without rain. Remember plants can go into stress mode after installation. Allow for 4 to 5 weeks for the plant to adjust.
Trees ~Water once a week for 2 to 3 minutes for the first 6 weeks. NO MORE.
Plants ~ Water once a week for 30 to 45 seconds for the first 3 weeks. NO MORE.
Perennials and Annual Flowers ~ Water daily, do not let water puddle, the plant may drown.
An over watered plant will usually die from the top down. A sign of over watering is withering leaves.
