Aloe Vera Cold Tolerance and Outdoor Winter Protection in Utah

Freeze Sensitivity

Aloe vera's gel-filled leaves freeze at 32°F, killing the tissue. In St. George, UT, winter lows regularly drop into the teens.

Options for a Large Specimen

1. Best: Remove offsets (pups), pot them, bring indoors.
2. Marginal: Wrap mother plant in heavy frost blanket + incandescent lights (not LED) on freezing nights.
3. Realistic: Accept loss of mother; propagate pups for next year.

Indoor Care for Pups

Bright light, water every 3–4 weeks, cactus mix, no fertilizer in winter.
