Garden Phlox is one of the most widely grown perennials in the US.
Their colorful flower heads are found in nearly all sunny perennial gardens and are
considered to be a one of the best plants available for midsummer color. Phlox
begins to bloom just as Summers heat set's in - here in zone 6 this is around the middle
of July. The plants continue to put on their wonderful show of color for about 8 -
10 weeks, depending upon variety. (Laura is a very long blooming variety)
Plants vary in heights ranging from 24 - 48 inches so pay close attention to this when
planning the garden. Butterflies find these plants irresistible as do many night
time pollinators - many species of moths are drawn to the sweet smells of Phlox as
well.
Growing Garden Phlox
Phlox should be grown in full sun to very light shade. Plants prefer a rich, well
drained, soil that has been amended with plenty of organic material. Feed in very
early spring, just as new growth begins with a side dressing of composted manure and
bone meal. Liquid feed in late spring, just as buds are beginning to show with fish
emulsion or compost tea. Mulch plants well to help keep the roots from drying out
but be careful not to mulch to deeply around the crowns as this can lead to crown rot.
In areas with high humidity powdery mildew can become a problem - to help prevent
this fungus do not water plants late in the evening. Plants flower better and longer
when deadheaded. Remove spent flower heads as they fade and cut plants back to the
ground in late fall. Large clumps of Phlox should be divided to keep them healthy -
usually about every 3 - 4 years.
Zones: 4-8
Propagation: Division & stem cuttings
Problems: Powdery mildew can be a problem
Notes: One of the best ways to combat powdery mildew is to spay
plants with a milk mixture. Mix 1 part milk with 4 parts water. Plants that
are stressed due to lack of water are more likely to be infected with powdery mildew -
always water your Phlox during dry spells.
