If you want to grow fruit indoors, strawberries are your best bet. They’re easy to plant bareroot, take up very little space, and since they are small fruits, they grow quickly to maturity indoors. Plant the right bareroot strawberry plants indoors right now, and you can enjoy fruit in as little as six weeks. Here’s how.
Choose the right bareroot strawberry variety
Day-neutral strawberry plants, which aren’t affected by day-length and tolerate temperatures between 35-89 degrees, are the best strawberries to grow indoors. The most reliable day-neutral strawberry is the Seascape strawberry. The medium-large berries of this plant are super sweet.
Prepare for strawberry planting
In a bucket, moisten well-draining, high-quality potting soil until it is damp. Fill a container that is at least 8 inches deep and 8 inches wide with soil to an inch below the rim.
In the meantime, soak the roots of the strawberry plants in water that contains a small amount of sea kelp or Superthrive for 1-3 hours.

Planting bareroot/dormant crown strawberry plants
Cut the roots of the strawberry plants by ¼ to ½ inch. Cut off any dead stems. Plant 3 to 4 inches apart in the prepared soil, making sure that the crown remains above the soil and the roots are submerged and running straight down into the soil. If you bury the crown, it will rot, and if you have exposed roots when you’re done planting, the strawberry plant will dry out.
Water the plants well after planting with warm water.
Place strawberry plants in a bright location
As fruiting plants, strawberries require a bright location to grow well and produce. Grow them in an unobstructed western, eastern or southern window. If the view is obstructed or if the plants don’t grow well and fail to fruit, put them under full-spectrum lighting.
After 4 weeks of growth.
Pollinate strawberry flowers when they appear
Foliage will appear on the plants within a week and flowers will come in about 3-4 weeks. When they bloom, take an unused child’s paintbrush and spread the bristles around in the flower so that pollen is moved from the stamen to the pistil.) Strawberries are self-fruiting, but they rely on wind or animals to do this outdoors.)
Water strawberries properly
As fruiting plants, strawberries should remain moist but not soggy. Water with warm water when the top inch of soil has dried out.
Fertilize strawberry plants regularly
Strawberries require a constant source of nutrients. Choose an organic strawberry fertilizer that is low on nitrogen and higher on phosphorus and potassium, such as our Super Berry Builder. A good food is designed for acid-loving plants.
After one week of growth.
Check for pests
Any indoor fruit is subject to pests, such as mealybugs and spider mites. Spray mealybugs with isopropyl alcohol and spider mites with neem oil.
