How to grow garden phlox
Phlox paniculata
When to plant garden phlox
Garden phlox is a clump-forming perennial set out as a plant and propagated by division. Plant in spring once the soil is workable; NC State notes adequate spacing and stem thinning improve air circulation against powdery mildew, and stems are cut to the ground in winter.
Garden Phlox is timed by season rather than your frost dates, so the planting calendar does not generate ZIP-specific dates for it. Check the cited sources below to fine-tune for your area.
