Growing Blueberries Indoors As a Houseplant

You can have good luck growing blueberries indoors, if you select a variety cultivated for this purpose. The Michigan State Experimentation Center cultivated the Top Hat Blueberry for indoor planting. You might also have success with lowbush blueberries, but they need cold weather during dormant season to produce berries.

Top Hat Blueberry

This indoor plant is for growing blueberries in containers. It’s a dwarf plant, which only grows to about 2 feet tall. For success with Top Hat blueberries, place your container in a sunny location in your house. It should get at least six hours of sunlight every day.

The blueberries produced by this bush are larger than the berries you usually see, even though the bush is smaller. One blueberry plant produces several pounds of berries toward the end of the summer. You can place these blueberry bushes outside during the warm weather, but it’s not required.

Sunshine Blue

This semi-dwarf blueberry bush grows to about 3 feet tall, making it a good variety to grow indoors. The blooms are hot pink and produce small, tangy blueberries. The bush is self-pollinating, so you only need one to get berries right at home. You can plant Sunshine Blue outdoors, in containers for patios or indoors in a sunny location.

Lowbush Blueberries

Lowbush blueberries are the low-growing bushes native to northeastern U.S. They require acidic soil with a pH of 4.5 to 5.0 and winter temperatures to produce berries. You can plant them indoors, as long as you put your containers in a cold location after the blueberry season is over for chilling. To produce berries, lowbush blueberries need about 1,000 hours of chilling at Chilling temperatures between 35°F (1.6°C) and 45°F (7.2°).

Caring for Indoor Blueberry Bushes

All blueberry bushes require the same kind of simple maintenance. As long as they have sunshine and water, they’ll stay healthy. Follow these blueberry maintenance tips to keep your bushes thriving:

  • Organic mulch – Spread mulch, pine bark or pine needles around the base of your bush to hold in moisture and add nutrients to the soil
  • Prune – During the dormant season, prune any dead canes from the base of the bush.
  • Water – Blueberries need a lot of water, so keep the soil moist but not saturated.
  • Sunshine – Provide at least six hours of sunlight daily

When it’s time to harvest your berries, pick them once per week. The berry clusters ripen at different times, so make sure they’re completely blue before you pick them. They can stay on the bush up to 10 days once they ripen.
