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. This variety has the best mildew resistance to date but all phlox benefit from good air circulation.
