How to Grow June Bearing Strawberries Indoors

Start June-bearing strawberries in early spring to take advantage of natural sunshine and summer temperatures. Prepare large, flat containers with drainage holes for June-bearing strawberries, which expand with runners or daughter plants. Containers should measure at least 6 inches deep.

Mix a rich, moist potting soil of one part organic compost to one part potting or garden soil. Strawberries require good nutrition and moisture retention, particularly in container situations. Incorporate granular 6-24-24 fertilizer for long-lasting nutrition. Fill the pots and containers to within 1 inch of their brims with this mixture.

Plant June-bearing strawberries just deeply enough to cover their root balls. Plant the seedlings close to the edges of the containers, but maintain 15 to 20 inches of space between multiple plants. If you're using small pots, give each strawberry seedling its own pot. Strawberries don't thrive in deep or shallow plantings, and require efficient drainage for growth.

Put the pots in sites with full sunshine, good air circulation and temperatures of 70 to 80 degrees F. Strawberries need bright sun and warmth for growth and eventual blooming. They won't produce blooms or fruit in shaded locations. Water the strawberries with 2 inches of water every week. Keep the strawberries in rooms with fans or open windows to encourage air circulation for pollination. Don't keep them in heated rooms as the hot air dries soil and foliage.

Feed the June-bearing strawberries with 12-12-12 fertilizer one month after planting to encourage best growth and eventual fruit harvest. Strawberries can't produce fruit without the right nutritional resources.
