I've transplanted several shrubs now some are 11 days old now and looking good. My question is this: how long do I need to water them? In other words, right now I'm putting 5 gallons of water on each one every evening, when should I slow this down to every other evening or more? I noticed tonight that the soil around the shrubs atill appeared to have some moisture in it but it's in the 90's every day lately. I don't want to over water them so....any help?
