If the phlox you just planted are the tall, sun-loving
paniculata type, you will want to give them enough room between phlox
plants for good air circulation. In zone 5 and other places that tend
to have hot humid periods in the summer, these phlox will often mildew
no matter what you do, but if they're too close to each other, the
mildew problem will be worse.
I have heard that some cultivars like "David" (a white) and
"Miss Lingard" are more mildew resistant. I have a "Starfire" in bloom
now and it's gorgeous with no mildew showing so far...
BTW, I have never had a mildew problem with the small annual
phlox, the open woodland types of phlox like stolonifera or divaricata,
or the alpine types like subulata or bifida.
The only other problem besides mildew is that the tall phloxes
tend to seed about a lot, pretty promiscuously, and the crosses often
become a sort of dull pink, so you might want to weed these out or move
them to a "fill-in" spot or a wild patch...
