Strawberry jars or strawberry pots are large urns with holes in the sides designed for growing strawberries and other plants that tend to droop. Gardeners insert a separate plant into each hole. As the growing season progresses, each plant will grow and hang down over the side of the pot, providing an attractive, leafy display. Ripe strawberries hang outside the terracotta pot, making them easy to pick and keeping them up out of the dirt.
Mix slow-release fertilizer with potting soil. Follow the directions on the fertilizer for the proportions of fertilizer and soil. Stir the mixture completely to thoroughly mix the fertilizer and soil.
Fill the strawberry jar with the potting soil mixture until you reach the bottom of the first row of holes. Place a strawberry plant in each hole, laying the roots onto the soil and leaving the rest of the plant hanging outside of the planter.
Add another layer of potting soil mixture, covering the roots of the first set of plants. Fill the pot until you reach the bottom of the second row of holes.
Place a strawberry plant into each hole with the leaves on the outside of the pot. Add more potting soil mixture to the pot, covering the roots of the plants.
Continue adding potting soil and plants until you reach a level about 3 inches below the top of the pot. Plant four strawberry plants in the top of the strawberry pot and add enough potting soil to cover their roots.
Water the strawberry pot thoroughly until all of the soil is saturated to the bottom of the pot. Place the pot in a location that gets at least 6 hours of sunlight per day.
Water your pot when the soil becomes dry. Turn the pot so that a different side faces the sun every time that you water. This will ensure every plant gets the same amount of sun.
