Mastering Indoor Strawberry Cultivation for a Tasty Yield
Love the taste of juicy, ripe strawberries, but lacking the outdoor space to grow them yourself? Fear not! With the proper conditions and care, you can easily cultivate these scrumptious treats right at home, even indoors.
We spoke to the pros, such as Jennifer Holston, a garden coach and home hydroponics specialist, and Dick Zondag, a master gardener, horticulturist, and owner of Jung Seed Company. They shared their insights and tips on how to grow these delightful berries without an outdoor garden.
Varieties to Try
Before getting started, it's essential to determine which strawberry varieties will thrive in your home environment. Jennifer recommends everbearing strawberries for their consistent yield and smaller, full-flavored berries. Alpine strawberries, in particular, can provide multiple harvests per year and often grow from seeds planted in the same year, like the alpine heirloom pineapple, which produces sweet, yellow berries with a hint of pineapple taste.
Seascape and albion are other great everbearing varieties, which grow larger than alpine strawberries. But planting from seed may take too long for these varieties, so it's recommended to opt for live plants instead.
Day-neutral strawberries are another option, producing fruit throughout the season. If you're hoping to extend your harvest, consider trying day-neutral varieties, such as Albion, Seascape, Evie II, San Andreas, and Ozark Beauty.[1]
When to Plant
Since you're not dependent on outdoor weather conditions, you can begin planting strawberries indoors at any time. However, you may find that live plants are only available or shippable during the growing season in your region. So, consider the best time to order or acquire your plant material based on your region.
Care Requirements
Growing strawberries indoors is similar to growing them outdoors, but with some adjustments to compensate for reduced light conditions and the lack of pollinators.
Temperature
Keep your home temperature between 65 to 75 degrees Fahrenheit (18-24 degrees Celsius) for optimal growth.
Lighting
You'll need to provide artificial lighting to compensate for the reduced natural light. Place your container-grown strawberries near a south-facing window if possible, and consider using supplemental grow lights to achieve at least 12-14 hours of light per day. Holston warns that insufficient lighting is often the leading cause of growth issues, so supplemental lighting is a must.[2]
Water
Water your indoor strawberries regularly, ensuring the soil is moist but not waterlogged. Manager the watering schedule by checking the soil's moisture every few days with your finger and adjusting the frequency as needed.[3]
Soil
Choose a well-draining, loamy soil mix that's rich in nutrients. Look for a potting mix specifically designed for container-grown plants, as they can be more finely-tuned for indoor growth conditions.
Pollination
Since there are no natural pollinators indoors, you'll need to be the one to promote pollination by gently transferring pollen from the male part of a flower to the female part using a small paintbrush.
Propagation
Strawberries can spread quickly by producing runners, which are small, vine-like stems that grow along the base of the plant. You can encourage propagation by directing these runners into new containers filled with a suitable potting mix, allowing them to root and grow into new plants within about a month. Once the new plants become established, you can separate them using a sharp knife to produce separate pots.
Harvesting
One of the benefits of indoor strawberry cultivation is that you won't have to compete with birds or other critters for your fruits. Patiently wait for the berries to turn completely red before harvesting, usually about four weeks after blossoming. Gently pluck or cut the berry from the plant wearing less than half an inch above the fruit to ensure healthy growth.
Frequently Asked Questions
- How many plants do I need?Depending on your needs, anywhere between 5 to 100 plants may be necessary to provide enough fruit for your family. If you're just looking for an occasional treat, less than ten plants should be sufficient.
- What's next?Consider exploring hydroponics to further enhance your indoor strawberry-growing experience. Jennifer Holston recommends using hydroponic systems for easier temperature and nutrient control, promoting faster growth and strawberry harvests.
