It’s best to water your roses early in the morning or in the evening when the temperatures are cooling off. After a day or two of heavy watering, rinse the bushes off with good, clean water.

This will keep the leaves from drying out and will also help keep your plants from getting too much sun. You can also water them at different times of the day. For example, if you want to plant a new rose bush in late summer or early fall, it may be best to wait until the last day of summer before you water it.
