Royal Poinciana Winter Protection for a 12-ft Tree in Zone 9

Floodlight Strategy for Large Trees

A 12-ft royal poinciana (Delonix regia) is too big for a frame cover. Instead:

• Place 3 floodlights: two on stepladders aimed at crown, one at base aimed up trunk.
• Run when forecast lows hit low 30s.
• Mulch root zone heavily (4–6″) if lows approach high 20s; pull back when warm.

Bloom Timeline

First flowers typically appear at 3–4 years. Each winter survived increases flower count. No need to add extra years for Zone 9 winters.
