How much water for new plants
I know this question has a lot of variables but I will get it started. What is the recommended way to irrigate new plants that are surrounded by rock. This is 1.5" limestone over fabric with many barberry's, lily's, hostas and assorted grasses.
Also, what is the required amount of water to get these plants to survive. I am in Minnesota and the plants were installed in Sept and the weather was pretty dry at the time. In the spring what would the best way be to keep these plants healthy.
I know the rock will retain heat and dry the plants if not watered sufficiently. I'm just looking for some expert advice on watering to keep them going.
