The compact size and trailing nature of strawberry plants make them convenient and ornamental choices for container planting. Use them around the perimeter of a window box or make homemade strawberry "towers" out of cedar boards, large plastic pipes or clean metal garbage cans. Or, try some of more classic ideas for productive, attractive strawberry pot gardens.
The classic terra cotta strawberry jar remains one of the most productive ways to grow strawberries in a container. The urn-shaped pots generally have cup-like openings on the side, originally designed to catch the "daughter" strawberries emerging from the runners of the mother plants. Use the pots for this purpose or to show off a few plants on your patio. Strawberry jars range from large, waist-high urns with about 20 holes, to smaller tabletop pots that hold five or six plants. For the larger pots, add a tube or pipe down the center for watering.
Whether you use a full-sized whiskey barrel or the type cut in half known as a "half barrel," you'll be able to grow significantly more strawberries than you can with traditional strawberry jars. Naturally, you'll grow about twice as many in a full-size barrel than in the half barrel. Strawberries grow from holes in the side of the barrel and are watered through a pipe placed in the center, which "weeps" moisture and liquid fertilizer through drilled holes.
Hanging Pots, Baskets and Bags
The trailing nature of strawberry runners, combined with the plants' flowers and their vivid fruit, make strawberries naturals for the hanging basket. Many nurseries sell kits containing pots with holes in the side and cords for hanging. A coiled-wire hanging basket lined with sphagnum moss is another option. Cut holes in the liner every 10 inches and insert the plants sideways before adding potting soil. The latest rage in nursery catalogues is hanging grow bags that hold strawberry plants or upside-down tomatoes. Most hanging bags are constructed from heavy-duty plastic, have strong handles and can hold about a dozen strawberry plants.
