Reviving Leggy Wave Petunias in Hanging Baskets: The 3-Week Pruning Plan

Wave petunia baskets were stunning for 6 weeks, now thinned, leggy (24–30"), still blooming. Alabama heat, afternoon sun, deadheaded, fertilized, watered regularly. Should you cut them back?

Yes — And Here's the Pro Schedule

Wave petunias flower at stem tips. Long stems = bare bases, few flowers. Regular cutting forces branching = more stems = more flowers.

Option A: Gradual Renewal (Recommended)

1. Week 1: Cut ⅓ of stems back by ½–⅔. Water well, then fertilize.
2. Week 2: Cut another ⅓ same way. Water only.
3. Week 3: Cut final ⅓. Water, then fertilize.
4. Ongoing: Mild liquid fertilizer every 2 weeks. Weekly, pinch 3–4 stems by half.

Option B: Hard Reset (Faster but Uglier)

Cut all stems back ⅔ at once. Water + fertilize. Bare for 2–3 weeks, then bushy rebloom.

Bonus: Root the Cuttings

Strip lower leaves, dip in rooting hormone, pot in moist mix. Bright shade until rooted. Free new plants!

Prune now — you'll have full, flower-packed baskets all summer.
