During summer, the bloom may start to give some brownish discoloration.
Not to worry, that’s only part of their developmental stage. This means their bloom season is over because they don’t flourish too much during summer. For this reason, don’t place the young plant in a very hot location, their location should be partly sunny.
Apply some mulch and a layer of compost to prevent weeds.Keep the soil of your plant moist especially during the hot periods.You can trim the stem after flowering to encourage a second bloom. You might as well need to cut the plant 2 inches down to encourage the renewal of the young stem.
Growing creeping phlox is pretty beneficial. Their maintenance is not so stressful. They will always come back next spring spreading their blooms outwards every year. Therefore you get to enjoy all year round amazing blooms.
