When to Bring Tropical Pots Inside in Zone 7b: Frost Threshold

Avocado (2), papaya, bougainvillea in pots, Central AL. Nights 55–65°F until Oct 1. When to move in at night?

Rule

Stay out until night temps dip below 35°F (frost risk). Then: night inside, day outside for sun.

FL growers use frost blankets. You: garage/sunroom at night, patio by day. All four species handle this shuffle.
