Tips For Successfully Growing Shrubs In Hot Climates
- Plant in the very early spring or in the fall to reduce transplant shock.
- Use arborist mulch to hold moisture and cool roots.
- Keep new plants consistently moist throughout their first season in the ground for the best results. Water deeply and less often, preferably during the early morning hours, once plants are established. Use the Finger Test to check soil moisture.
- Prioritize native or regionally adapted plants that already know how to roll with Ma Nature's heatwaves.
- Group by water needs and plant in layers. Groundcovers, shrubs, and trees all work better together.
- Deadhead blooms as needed to encourage more flowering. Here's all about deadheading.
