garden phlox

Garden phlox (Phlox paniculata 'Delta Snow') should be watered consistently, but not excessively. In warm temperatures, it should be watered about once a week, making sure the soil is moist but not soggy. In cooler temperatures, it should be watered less frequently, about once every 2 to 3 weeks. Make sure to water at the base of the plant, taking care not to get the foliage wet which can spread diseases. During the blooming season, watering more frequently will result in more flowers. When the soil is dry to the touch it is time to water.

Garden phlox (Phlox paniculata 'Delta Snow') thrives best when grown in full sunlight throughout the day. To achieve the very best growth and flowering, it requires 6 or more hours of direct sunlight each day. It can also tolerate partial or dappled shade for a few hours during the hottest parts of the day.

Garden phlox (Phlox paniculata 'Delta Snow') should be pruned after the flowers have faded, typically in late summer to early fall (August or September). Prune plants to remove spent flowers, branch ends, and any dead or diseased foliage. Avoid pruning if possible unless absolutely necessary; too much pruning can limit flowering potential and cause damage to the plant. A light trimming to shape the plant and remove any weak or crossed stems will be beneficial to encourage full, bushy growth. If necessary, a radical pruning should be done in early spring, before new growth begins. Be sure to use sharp pruners and sterilize them with alcohol between each cut.
