Phlox is a perfect perennial plant, perpetually pleasing people. It is easy to improve your Phlox performance.
Tips for getting good Phlox flowers.
- On mature clumps of Phlox thin out any congested, woody stems.
- Thinning out improves subsequent flowers and increases air flow.
- After a good rain, mulch around your Phlox to conserve moisture.
- Phlox responds to the Chelsea chop – cut some of your Phlox back by a half at the end of May. You will then get lush growth and later flowers.
- I feed with a slow release fertilizer like Growmore in early spring.
Mildew Problems
- Phlox are prone to mildew but it won’t kill the plant – Phlox will come back next year.
- Water stress is a main cause of Pholx mildew so water the roots, avoid splashing the leaves and mulch as above.
- Lack of air circulation is another cause of mildew.
- In Autumn tidy up all fallen leaves.
- Mildew attacks young sappy growth so do not over fertilize with nitrogen.
