Ridding Your Phlox of Mildew

Darrin Duling, director of The Native Plant Center:
"Mildew is a common problem with garden variety summer phlox and is best prevented by proper siting: planting in full sun in open areas with good air circulation, with little or no overhead watering is a good first-line defense.. Further to this, select so-called mildew-resistant varieties (note "resistant" vs. "mildew-proof"). Here are a few: 'David' and 'Delta Snow' - white flowers, 'Eva Cullum' - pink, 'Katheriine' - lavender, 'Laura' - light purple w/ white eye, and 'Starfire' - hot pink. These are some of the better-known varieties that are said to resist mildew, but by no means is this a comprehensive list.
~ I recently attended a lecture given by Tony Avent, owner of Plant Delights Nursery in Raleigh, North Carolina, in which Tony extolled the virtues of Phlox 'Minnie Pearl'; a naturally-occuring native phlox hybrid discovered growing wild in Mississippi that has so far shown no mildew problems. As an added plus, this phlox has a dwarf habit - only growing 1' tall, is extremely floriferous with sparkling white flowers, and blooms about a month earlier than other phlox of its kind. Tony also offers many other varieties of phlox that he has found to survive the steamy summers in Raleigh with little or no mildew problems. These, along with many other excellent native plant selections that he has trialed, may be viewed in his catalog posted on the Plant Delights Nursery website."
