Answer: Plants in containers always need more water than the same plants grown in the ground. If you are waiting for cooler weather to plant your perennials in the ground, you can still plant them now and then protect them from hot sunshine for about 10 days while their roots are getting established. Just prop up a screen or screen cloth stretched between a couple of stakes that you drive into the ground. Or, if you want to keep the plants in containers so you can move them around in the garden or use them on a patio, they will be fine in containers but you should check them every day and water as needed. Hope this answers your question!
