DETAILS

Care Instructions
Garden phlox requires regular watering to keep the soil evenly moist, especially during dry periods. It thrives in full sun but can tolerate partial shade. Moderate temperatures and average humidity levels are ideal for its growth. Regular deadheading of spent flowers can encourage more blooms.
Soil
Phlox paniculata prefers well-draining loamy soil that is rich in organic matter. The soil should be kept evenly moist but not waterlogged. Good drainage is essential to prevent root rot.
Fertilizer
A balanced fertilizer with an N-P-K ratio of 10-10-10 can be applied in early spring and again in mid-summer to promote healthy growth and abundant flowering. Avoid over-fertilizing, as this can lead to excessive foliage growth at the expense of flowers.
Repotting
While garden phlox is typically grown outdoors, if grown in containers, it should be repotted every 2-3 years in early spring. Choose a pot that is slightly larger than the current one and use fresh, well-draining potting mix.
Propagation
Phlox paniculata can be propagated by division in early spring or by taking stem cuttings in late spring to early summer. Ensure that each division has several healthy shoots and roots. Cuttings should be taken from non-flowering stems and rooted in a moist, well-draining medium.
Pruning
Pruning is essential for garden phlox to maintain its shape and encourage more blooms. Deadhead spent flowers regularly and cut back the stems to the ground after the first frost in late fall. In early spring, remove any dead or weak stems to promote healthy new growth.
Toxicity
Phlox paniculata is not known to be toxic to pets or humans. It is generally considered safe to grow in gardens where children and pets are present.
Additional
To prevent powdery mildew, ensure good air circulation around the plants by spacing them adequately and avoiding overhead watering. Mulching around the base of the plants can help retain soil moisture and suppress weeds.
