Crape Myrtle Training: From Bush to Tree Form on Long Island

Newly planted crape myrtle on Long Island (zone 7) can be trained into a small tree with proper pruning.

Pruning for Tree Form

• When: Now (after bloom) or late winter.
• Action: Remove lower limbs to desired trunk height.
• Shape: Select 3–5 main trunks; remove competing shoots.
• Maintain: Annual removal of suckers and low branches.

Side-Dressing Explained

Apply composted manure/fertilizer around the plant (not on crown)—like dressing a salad. Feeds roots without burning.

Long Island Success

• Zone 7 supports tree form (like Memphis/Atlanta).
• Full sun, well-drained soil.
• Water first year; then drought tolerant.

With patience, your bush becomes a graceful multi-trunk specimen.
