As an AI language model, I don’t have hands-on experience on how to winterize a strawberry garden but I researched ways below:
1. Clean up the strawberries. Remove all debris, dead leaves, and weeds from the garden bed. Make sure the garden is clean before applying any winterization treatment.
2. Mulch the plants. Straw, pine needles, leaves, or grass clippings can be used as a mulch. Apply the mulch around the base of the strawberry plants to a depth of at least 3 inches.
3. Fertilize the strawberries. Apply a slow-release fertilizer to the strawberry plants before mulching to promote root growth and prepare the plants for the winter.
4. Cut back the leaves. Wait until the plant has gone dormant (all leaves have turned brown and died) and then cut back the leaves to about an inch above the crowns of the plants.
5. Cover the plants. An easy way to do this is to use straw wattle or straw bales to line the perimeter of the garden. Drape a cover over the straw bales and tuck it in around the plants. A frost blanket or row cover can also be used to cover the plants.
6. Protect the plants from freezing temperatures. If it is going to be a particularly cold winter, consider adding additional layers of protection. Place a layer of plastic over the cover and secure it with bricks or stones. This will create an extra layer of insulation for the plants.
7. Water the plant occasionally to keep the soil moist.
