Hey there, fellow crape myrtle lovers! If your Southern Charm beauties put on a spectacular first show in late spring and early summer (which they certainly are here in North Florida), but are now looking a bit tired with heavy seed pods weighing down the branches, you’re not alone. July marks the beginning of “second bloom” season for many of us in zones 8a–9b (and similar), and one simple technique can coax gorgeous new flowers right through fall.
Deadheading — What a Terrible Name! Deadheading isn’t the heavy winter pruning many people confuse it with — it’s a light, targeted midsummer trim that redirects energy from seed production back into fresh growth and blooms. You’re not really removing “dead” growth; you’re preventing those seed pods from fully developing, which encourages the plant to set another round of flowers.
Important Note: Deadheading is not necessary for healthy crape myrtles. Many trees bloom beautifully with just one long flush, especially with proper fertilization. This is especially true for giant varieties where reaching all the spent clusters may be impractical or impossible. It’s simply an optional boost for those who want extended color.
Why Deadhead in July?
Crape myrtles bloom on new, green wood. Once the first flush peaks (often around July 4 in the Deep South), spent flower clusters turn into those hard, glossy round seed pods. These pods are heavy and can cause branches to droop while signaling the plant to slow down flowering.
By removing them when roughly 15–20% of the blooms remain (or when most clusters have faded and pods are forming), you encourage the tree to push out new shoots and buds. With warm weather still ahead, this often leads to a strong second (and sometimes lighter third) flush from late July into October, depending on variety, watering, and feeding.
How to Deadhead Step-by-Step
- Timing — Wait until the majority of the first bloom cycle has faded but before it’s completely done. Mid-to-late July is ideal in Florida and the Southeast for a solid second show. If you’re farther north in zones 6 & 7, give it another month or so.
- Tools — Clean, sharp bypass pruners for small plants or a pole pruner/saw for taller ones. Disinfect between plants if needed.

Technique:
- For dwarf and compact varieties (under 10–12 ft): Simply snip off the spent flower cluster just below the base of the panicle, taking a couple of inches of stem into a healthy outward-facing bud or leaf node. This keeps the plant neat and bushy.
- For mid-size to taller varieties: You can be a bit more aggressive — remove 1–4+ feet off the spent tips depending on overall size and desired shape. This stimulates more branching and flowers without harming the plant’s structure.
- Cut at a 45-degree angle to promote quick healing. Avoid stripping too much foliage, if you can.

Pro Tip: Learn to distinguish between developing flower buds (smaller, tighter clusters that will open into blooms) and mature seed pods (hard, round, glossy, and forming after flowers fade). Don't remove healthy flower buds silly! — you only target the spent clusters that have already bloomed.
Seed Pods:
Buds:
- Clean Up — Remove and discard (or compost away from the plant) the seed pods to reduce any disease carryover.
Important Note: This is not the same as winter structure pruning (late winter/early spring, before new growth). Summer deadheading is lighter and focused only on spent blooms.
Feed Lightly for Best Rebloom
After deadheading (or even if you skip it), the addition of a bloom-booster fertilizer (higher in phosphorus and potassium, lower in nitrogen) will help the plant set another round of flowers. Avoid heavy nitrogen feeds this late in the season, as they push leafy growth at the expense of flowers.
Water deeply after feeding and maintain consistent moisture (but not soggy soil) through the rebloom period. A layer of mulch helps retain moisture and moderate soil temps.
What Happens When I Don't Deadhead?
Nothing....well, that's not entirely true. A whole lot of something happens! Healthy crape myrtles will normally put on a second show without deadheading. And it's nice to let the plants go to seed as part of their yearly reproductive life cycle. Once they have dried this fall, you can harvest the seeds and sprout them next spring. Or better yet, leave them on the plant over winter to provide a significant food source for small birds!
Common Mistakes to Avoid
- Waiting too long (into September) — not enough warm days left for new buds to develop fully.
- Over-pruning or “topping” — this can stress the tree and lead to weak, leggy growth.
- Removing healthy flower buds instead of spent pods.
- Confusing it with dormant pruning — save major shaping for February/March.
