When a gardener renovates strawberry plants at the end of the growing season, a strawberry patch receives fresh energy for growing and producing fruit in the next growing season. A gardener should remove old strawberry plants because this will give new plants a chance to grow and develop into main strawberry producers. Weed control and fresh fertilizer application are a part of strawberry renovation as well.
Trim down the foliage of the oldest bearing strawberry plants. Trim off the leaves and upper stems, but do not disturb the crowns of the strawberry plants.
Apply the complete fertilizer to the soil around the strawberry plants. Use 10 to 20 pounds of fertilizer for every 1,000 square feet of strawberry plants. Leave the fertilizer on the top of the soil. Be careful not to sprinkle fertilizer onto any foliage that may exist.
Use the rototiller or the garden spade to cultivate the soil around the strawberry plants. This will remove weeds, narrow the plants and work the fertilizer into the soil. As you work the soil, you may remove older plants in the process and this is expected.
Provide generous amounts of water after cultivating the soil. Saturate the soil down to at least eight inches all around the strawberry plants. Sufficient water at this stage will help the plants begin to grow again, will encourage new strawberry plants to grow and will dissolve the fertilizer into the soil.
Apply the nitrogen fertilizer along the sides of the strawberry plants at the end of the summer. Sprinkle between four and six pounds of fertilizer over the soil for every 1,000 square feet of growing area. Work the fertilizer into the soil and water the strawberry plants generously after fertilizing.
