The Best Time Of
Year To Divide Phlox In
Your Garden
By SAKSHI KHAITAN
Phlox will show several signs when it's time to divide them, including bearing fewer blooms, showing sparse foliage, or growing in a circle with a bald middle patch.
Target dividing the plant during the fall after it has bloomed completely. Alternatively, phlox can also be divided in the spring before it grows new shoots.
It's best to divide phlox when the temperature is cool, as heat can dry up the stressed plant. Ideally, split the plant at least four to six weeks before the season's first frost.
Carry out such propagation every two to four years if the phlox shows strong growth, and include at least three to five shoots with roots intact for successful transplantation.
