Select 3- to 5-gallon pots with drainage holes for individual plantings, or expand to larger containers for row plantings. Give strawberries room for root growth with 6-inch-tall pots. Always use pots and containers with drainage holes, as strawberries rot in standing water.
Fill the pots with a mixture of half organic compost and half garden loam. Strawberries thrive in this rich, crumbly and loose mixture. Turn 6-24-24 granular fertilizer into the soil for best root development. Follow manufacturer directions in regard to fertilizer quantity.
Plant successful day-neutral cultivars such as Tristan and Tribute, or a combination of different cultivars. Plant one seedling per small pot or multiple seedlings at every 15 inches in larger containers. Plant strawberries just deep enough to cover the root balls.
Water the strawberries with 2 inches of water and give them 2 inches of water every week, or whenever the soil starts to go dry. Don't allow strawberries to go dry.
Put the pots in a site with six to eight hours of natural or artificial light every day. Strawberries will grow with partial shade but won't bloom or bear their fruit. Keep the fruit away from any hot air in the house, as this dries the plant foliage. Maintain temperatures of 65 to 75 degrees Fahrenheit for strawberry growth.
Feed the strawberries with 12-12-12 granular fertilizer two to three weeks after planting, when the plants begin to grow. Mix the fertilizer into the soil to the side of each seedling, then water. Follow manufacturer directions in regard to fertilizer quantity.
