A strawberry jar is a pot with planting pockets unevenly spaced around the outside. For gardeners with limited growing space, strawberry jars are a good way to grow a crop of delicious strawberries. Place a strawberry jar on a balcony or patio, and you'll have fresh berries all summer. Strawberry jars are fun to plant, easy to care for, and require no bending, stooping or weeding.
Purchase enough strawberry plants to fill each pocket in the strawberry jar, plus three or four plants for the top of the jar. The best strawberries for jars are everbearing plants such as Quinalt or Ozark Beauty, which will produce berries three times between summer and fall.
Cut a piece of plastic pipe about an inch longer than the height of the strawberry jar. Use a drill to make several holes in the pipe. The pipe will enable you to water the strawberry jar evenly.
Place the plastic pipe vertically in the center of the pot. Hold the pipe in place with one hand while you fill the strawberry jar up to the bottom of the first pocket, using commercial potting soil.
Place a strawberry plant in the pocket, then add enough potting soil to bring the soil level up to the next pocket.
Continue planting and adding soil one pocket at a time. Fill the container to within an inch from the top of the container. Plant three or four strawberry plants in the top of the strawberry jar.
Fertilize the strawberry jar using a balanced, time-release fertilizer. Read the directions on the fertilizer label for specific use and rates of application.
Water the strawberries thoroughly, watering the pockets individually as well as watering through the plastic pipe at the core of the pot. Check the strawberry jar daily, and keep the soil moist. Remember that containers dry out quickly. Water the strawberry jar daily during hot, dry weather.
