Imagine biting into a juicy, sun-ripened strawberry in the dead of winter. Sounds like a dream, right? Well, what if I told you that with a little planning and effort, that dream could become a reality? Let's dive into the wonderful world of winter strawberry growing!
Can You Really Grow Strawberries in Winter? The Truth About Winter Strawberries
Yes, you absolutely can grow strawberries in winter, although it requires a bit more dedication than a typical summer strawberry patch. The key is understanding the specific needs of strawberry plants and providing the right environment for them to thrive even when the weather outside is frightful. Forget those grocery store, pale imitations! Homegrown winter strawberries offer a flavor explosion you won't soon forget.
Understanding Strawberry Varieties and Their Cold Tolerance
Not all strawberries are created equal when it comes to cold hardiness. The success of growing strawberries in winter hinges heavily on selecting the right variety. There are three main types of strawberries:
- June-bearing: These produce one large crop in late spring or early summer. They're generally not ideal for winter growing unless you have a very controlled greenhouse environment.
- Everbearing: Despite the name, everbearing varieties don't produce fruit continuously. They typically have two or three harvests throughout the year – one in spring, another in late summer, and possibly a small one in the fall. They are more suitable than June-bearing varieties for winter production, especially if you provide protection.
- Day-neutral: These varieties are the best choice for winter strawberry growing. They produce fruit consistently throughout the growing season, regardless of day length, as long as temperatures are within a suitable range (ideally between 50°F and 85°F).
Popular day-neutral varieties suitable for winter growing include:
- Albion
- Seascape
- Chandler (often grown as an annual in warmer climates, but can be overwintered with protection)
Choosing the right variety is paramount to your success. Research and select a variety known for its adaptability and consistent fruiting habit.
Preparing Your Strawberries for Winter Growing
Whether you're starting with established strawberry plants or new ones, preparation is crucial for successful winter strawberry production. Here's what you need to consider:
Starting with Established Plants
If you already have strawberry plants in your garden, you can transplant them into containers for indoor growing. Select healthy, vigorous plants and carefully dig them up, ensuring you retain as much of the root system as possible. Plant them in pots with good drainage, using a high-quality potting mix. Ensure the crown of the plant (where the roots meet the stems) is just above the soil line. Water thoroughly after planting.
Starting with New Plants
Bare-root strawberry plants are a cost-effective way to start a winter strawberry garden. Soak the roots in water for about an hour before planting. Plant them in containers as described above, ensuring the crown is properly positioned. You can also start strawberries from seed, but this takes longer and requires more patience. Start seeds indoors 8-10 weeks before you plan to move the plants into their final growing location.
Soil and Container Considerations
Strawberries prefer well-draining, slightly acidic soil (p H 5.5-6.5). Use a quality potting mix that's specifically formulated for containers. Avoid using garden soil, as it can become compacted and poorly drained in pots. The size of your container will depend on the variety of strawberry you choose. Generally, a 6-8 inch pot is sufficient for one plant. Make sure the container has drainage holes to prevent waterlogging.
Creating the Ideal Indoor Environment for Winter Strawberries
Since winter conditions aren't conducive to strawberry growth, you'll need to create an artificial environment that mimics their preferred growing conditions.
Light Requirements
Strawberries need at least 6-8 hours of sunlight per day to produce fruit. In winter, this can be a challenge, especially in northern climates. Supplement natural light with grow lights. LED grow lights are energy-efficient and provide the full spectrum of light that plants need. Position the lights about 6-12 inches above the plants. A timer can automate the light cycle.
Temperature and Humidity
Strawberries thrive in temperatures between 60°F and 80°F. Avoid exposing them to temperatures below 50°F, as this can damage the plants. Keep them away from drafts and cold windows. Maintaining adequate humidity is also important. Indoor air tends to be dry in winter. Increase humidity by using a humidifier, placing the pots on trays filled with pebbles and water, or misting the plants regularly.
Watering and Fertilizing Your Winter Strawberry Plants
Water strawberries regularly, keeping the soil consistently moist but not soggy. Overwatering can lead to root rot. Check the soil moisture by sticking your finger into the top inch of soil. If it feels dry, it's time to water. Use a balanced liquid fertilizer every 2-3 weeks to provide the nutrients the plants need to produce fruit. Follow the instructions on the fertilizer label carefully. During the blooming and fruiting stages, you can switch to a fertilizer higher in phosphorus and potassium to encourage fruit development.
Keeping all your gardening tools organized is key to efficient winter strawberry growing, especially when you're working indoors. A well-organized space makes the process much smoother.

Pollination Strategies for Indoor Strawberries
Indoor strawberries won't be visited by bees or other pollinators, so you'll need to hand-pollinate them. Use a small, soft paintbrush to transfer pollen from one flower to another. Gently brush the inside of each flower with the paintbrush, paying particular attention to the center of the flower (the stigma). Do this every day or every other day when the plants are in bloom. Alternatively, you can use a small fan to circulate air around the plants, which can help to distribute pollen.
Troubleshooting Common Problems
Even with the best care, you may encounter some problems when growing strawberries indoors in winter. Here are some common issues and how to address them:
- Pests: Aphids, spider mites, and whiteflies can be a nuisance. Inspect your plants regularly and treat any infestations promptly. Insecticidal soap or neem oil are effective organic options.
- Diseases: Fungal diseases like powdery mildew can occur in humid conditions. Ensure good air circulation and avoid overhead watering. Treat with a fungicide if necessary.
- Lack of fruit: Insufficient light, improper pollination, or nutrient deficiencies can all contribute to a lack of fruit. Ensure your plants are getting enough light, hand-pollinate regularly, and fertilize appropriately.
- Yellowing leaves: This can indicate overwatering, underwatering, or a nutrient deficiency. Adjust your watering schedule and fertilize as needed.
Harvesting and Enjoying Your Winter Strawberries
Strawberries are ready to harvest when they are fully red and slightly soft to the touch. Gently twist or snip the stem near the berry. Pick the berries regularly to encourage continued production. Enjoy your freshly harvested winter strawberries in salads, desserts, or simply eat them straight from the plant. They'll be a welcome taste of summer in the midst of winter!
