Select a pot for the strawberry plants that complements the color and style of the bird cage. It needs at least two drainage holes in the bottom. Select an attractive cage with a removable bottom.
Fill the pot with soil-less potting mix and place one or two strawberry plants in the pot. Select healthy strawberry varieties that are known to grow well in your climate. Everbearing and day-neutral types are usually grown in pots because they bear fruit all summer long, starting the first season.
Remove the bottom of the bird cage and set the strawberry pot on it. Reassemble the bird cage and place it in a sunny location. Strawberry plants need at least eight hours of sunlight each day to produce fruit.
Water the strawberry plants to keep the soil evenly moist. During hot weather, this may be every day. Do not water so much that the soil is soggy though, which rots the roots.
Fertilize the strawberry plants every two to three weeks during the growing season with a water-soluble balanced fertilizer, according to package directions. Strawberries in pots need more frequent fertilizing than those in-ground to meet their nutritional needs.
