How to Winterize Potted Strawberry Plants

Overview

Although strawberries are tough enough to withstand a mild freeze, they won't withstand long, hard freezes. Because potted strawberries don't have the same protection that ground-grown strawberries do, it's especially important to winterize them before winter sets in. However, strawberries require a cold period, so don't winterize them until the nighttime temperatures are consistently below freezing.

Step 1

Water the potted strawberry plants in late autumn before preparing them for the winter. Remove straggling leaves and cut back any dead foliage.

Step 2

Cover the strawberry pot with bubble wrap and put the pot in a sheltered spot near the wall of your house, or in a garage or shed. Water the soil occasionally so it doesn't dry out completely.

Step 3

Bring the strawberry pot out and remove the mulch and bubble wrap when the temperature reaches about 30 degrees Fahrenheit. Water the strawberries and feed them a dose of fertilizer formulated for tomato plants.

Step 4

Replace the strawberry plants with new plants every 2 to 3 years. Wash the pot and start with fresh potting soil.
