Temperatures are forecasted to drop into the 20s tonight. Sensitive plants, such as young citrus trees (planted in the summer or later), citrus in raised planters, and various succulents, may require protection from the cold.
For sensitive plants that you can not move indoors, we recommend plant blankets, which are sold at most hardware stores. Drape the plant from top to bottom, allowing extra material to fall onto the soil. Secure blankets with lawn staples, heavy rocks, or bricks.
