Some plants like morning sun and cooler shade in the afternoon. Others can tolerate warm summer sun all the time.

The best way to solve this issue is to choose the correct shrubs or perennials which stay the desired size in the first place without lots of pruning.

Ok, this can be complicated with mother nature but lets keep it simple. Water the plants well so soil is thoroughly moist. For new plants two or three times a week until established. Trees will be at least once per week. For planters and baskets check the weight of container to determine if watering is necessary.
