Strawberries are a beloved garden fruit and are fairly easy to grow, but sometimes they can be frustratingly unproductive. Understanding the reasons behind their lack of flowers and fruit can help you address the issues and enjoy a bountiful harvest.

Understanding Strawberry Varieties and Their Fruit Production
There are many different strawberry varieties out on the market and not knowing which variety you’re growing could be cause for your strawberry plant not flowering.
Everbearing vs. June Bearing Varieties
Strawberry plants come in different varieties, primarily everbearing and June bearing. It’s crucial to know which type you have to set realistic expectations for fruiting.
- Everbearing Strawberries: These varieties produce two to three harvests per year, typically in the spring, summer, and fall. They are ideal for gardeners looking for a continuous supply of strawberries.
- June Bearing Strawberries: These produce a single, large crop in late spring to early summer. They tend to have a more intense, flavorful yield, but the fruiting period is shorter.
The Life Cycle of Strawberry Plants
Strawberry plants have a limited lifespan when it comes to peak fruit production. Typically, they produce best in their second and third years. After about four to five years, their productivity declines significantly. New strawberry plants, or those coming out of dormancy, need approximately three to four months to start producing fruit. If your plants are young or just awakening from winter, patience is key.
Nutrient Deficiencies and Soil Health
Whether you take the natural approach to gardening, or you prefer to fertilize with store-bought products, balancing out your strawberry nutrients could be a huge impact on your strawberry plant not flowering.
Feeding the Soil, Not Just the Plant
Strawberries require a balanced diet of nutrients to thrive, and this starts with healthy soil. A regenerative or permaculture approach focuses on feeding soil microbes, which in turn provide nutrients to the plants. Compost is a fantastic way to achieve this, offering a diverse array of nutrients and improving soil structure.

Too Many Nutrients
While nutrient deficiencies can hinder flowering and fruiting, over-fertilizing can also be detrimental. Too much nitrogen, for instance, can lead to lush, leafy growth at the expense of flowers and fruit.
Apply a balanced, homemade compost as a top dressing at the beginning of the year and again in the middle of summer. This ensures your strawberries get the nutrients they need without the risk of over-fertilizing.
Pollination Issues
Strawberries rely on pollinators like bees to transfer pollen from flower to flower, leading to fruit development. Without adequate pollination, flowers may bloom but fail to set fruit.
Creating a Pollinator-Friendly Garden
To attract pollinators, your garden should be a sanctuary for them, starting early in the season. Consider adding bird baths, planting pollinator-friendly plants such as lavender, marigolds, and borage, and avoiding the use of pesticides that can harm these beneficial insects.
Water Management
Strawberry plants have shallow roots that absorb water from the topsoil. Both overwatering and underwatering can affect their ability to flower and fruit.
- Overwatering: Can lead to root rot and other diseases.
- Underwatering: Can cause plants to dry out and stop producing flowers and fruit.
Set up a drip irrigation system to water strawberry plants for 10-15 minutes every 3-4 days, depending on the temperature. Perform a finger test to check soil moisture levels and apply a layer of mulch to help retain moisture.
Temperature Stress
Strawberry plants prefer cooler temperatures and can struggle in extreme heat. In regions with hot summers, such as where I grow in Southwest Missouri, the heat can stunt strawberry plants and inhibit fruit production.
Grow strawberries in a partially shaded area to provide relief from the intense summer heat and prevent stress on the plants.
Overcrowding and Competition
Strawberry plants produce runners that can root and grow into new plants. If left unchecked, these runners can create a dense, overcrowded patch that competes for resources, reducing overall productivity.
In early spring, thin out excess plants by separating or digging them up. Additionally, you can monitor for new runners in summer and fall, and pot them in 4-inch containers to root before relocating them or sharing with friends.
