Crepe Myrtle Winter Care in Northern Ohio: Burlap Not Plastic

Your Virginia-sourced crepe myrtle (Lagerstroemia) in Northern Ohio (Zone 5b-6a) suffered from plastic wrap winter protection — the "greenhouse effect" on sunny winter days cooked buds and cambium, causing dieback. The sprouts from the base are root suckers, not recovery of the original top.

Why Plastic Failed

• Traps solar heat: 20-40°F above ambient on sunny days
• Freeze-thaw cycles: Tissue activates then refreezes — lethal
• No gas exchange: CO2 buildup, O2 depletion
• Moisture trap: Condensation freezes on tissue

Correct Winter Protection

1. Burlap wrap: 2-3 layers, stakes 6" from plant, open top
2. Mulch: 6-8" shredded leaves/bark after ground freezes
3. Anti-desiccant: Wilt-Pruf late Nov (above 40°F)
4. Wind screen: Burlap on NW side if exposed
5. No plastic: Ever. Not even "breathable" plastic.

Current Plant Assessment

• 3' tall with basal sprouts: Original top likely dead
• No flowers: Blooms on new wood; may bloom on suckers if mature
• Decision point: Train best sucker as new trunk, or replace

If Training a Sucker

1. Select strongest, straightest basal shoot
2. Remove all others at ground level
3. Stake loosely; protect as above
4. Fertilize 5-10-10 fall + spring
5. Expect 2-3 years to tree form

Hardier Cultivar Options

If replacing: 'Natchez', 'Muskogee', 'Tuscarora', 'Arapaho' (Zone 6 hardy). Plant in protected microclimate (south wall, courtyard).

Plastic wrap is the #1 crepe myrtle killer in cold climates. Burlap, mulch, and anti-desiccant = survival.
