Ongoing Management
Insect & Disease Control
Garden Phlox can be susceptible to some diseases, including powdery mildew, spider mites, and aphids. Regular monitoring, proper spacing for air circulation, and providing adequate sunlight and water can help prevent and manage these issues.
Fertilization
Feed Phlox in the spring with a balanced, slow-release fertilizer to promote strong growth and plentiful blooms.
Watering
- Garden Phlox performs best with regular watering, especially during dry spells. However, avoid overhead watering to reduce the risk of powdery mildew, a common problem with garden phlox.
- Apply a layer of mulch around the base of the plants to retain soil moisture and suppress weeds.
Pruning / Cutting Back
- Deadhead spent flowers to encourage a second bloom.
- Cut back your Phlox to ground level in late autumn or early spring to help rejuvenate the plant.
Propagation
Divide the plants every 2-3 years in early spring to maintain vigor and control their spread.
