Growing and Maintenance Tips

Phlox needs rich, well drained soil that does not dry out to look its best. It is a heavy feeder so a fall mulch with compost is beneficial to keep up the organic level in the soil. The varieties we sell have mildew resistant but do not overcrowd this plant. It needs good air circulation.
