Growing strawberry plants on a porch is remarkably easy when grown in containers. A perennial plant, strawberries can produce fruit from three to five years until needing to be replaced. There are two main varieties of strawberry plants--summer bearing, which produce one crop from late spring through June, and the ever bearing variety that produces two crops in early and late summer. For container strawberries, the ever bearing variety is the best since it has fewer runners than the summer variety, meaning it does not need to be replaced until it stops producing fruit.
Select a container that is at least 12 inches deep to allow for deep root growth of the strawberry plants. Choose either a ceramic or clay container.
Fill the container with potting soil to within 1 inch of the rim. Pinch off all but the top one or two sets of leaves on the strawberry plants and plant deeply in the container, up to the first set of leaves. Allow four to six plants per 12-inch diameter container, spacing several inches apart.
Place the container in a sunny location on the porch where the plants will receive full sun each day. Some partial afternoon shade is tolerated, but strawberries grow best in full sun all day long.
Water your strawberries well after planting and keep watered on a regular basis to ensure the soil stays moist, but never soggy. Watering two to three times weekly is usually sufficient and more in the summer months if needed when it is warmer.
Feed the strawberry plants with a slow-release high-phosphorus fertilizer, 5-10-5, to ensure an abundance of fruit. Fertilize once a month during early spring through late summer, then stop in the fall and winter.
Cover with netting if needed to keep birds from eating the strawberries. If slugs pose a problem, set out slug bait traps around the bottom of the containers, which can be purchased at your local gardening store.
Bring your container strawberry plants indoors during the winter as temperatures drop to freezing. Keep them in a cool basement or garage and water a couple times weekly just to keep the soil moist. No fertilizer is needed during the winter. Set the plants back outside after the danger of the last frost has passed.
