Adjust schedule seasonally to allow for deep, infrequent watering in order to maintain an even moisture level. About 1" of water per week in the summer is a good starting point. When possible add 1 tablespoon of natural apple cider vinegar per gallon of water. Use a siphon attachment and include a light application of seaweed, molasses, and compost tea when possible also. Don't use vinegar with acidic water or soil.
