Tips for Success with Hot-Sun Shrubs
- Water deeply during establishment. Even drought-tolerant shrubs need regular watering in their first year.
- Mulch around the base. A layer of mulch helps retain soil moisture and keeps roots cool.
- Plant in well-drained soil. Most sun-loving shrubs will rot in heavy, wet soil.
- Give them space. Plant shrubs at their mature width to ensure good airflow and prevent overcrowding.
- Prune at the right time. Spring bloomers like lilac and mock orange should be pruned right after flowering. Summer bloomers like butterfly bush and crape myrtle can be pruned in late winter or early spring.
