Did You Know?
1. Did you know that strawberries are not actually berries? They belong to the rose family and are considered aggregate fruits because they develop from a single flower with multiple ovaries.
2. In ancient Roman times, strawberries were believed to have medicinal properties and were used to treat a wide range of ailments, including melancholy, fever, and fainting spells.
3. The first strawberries cultivated in North America were larger and more flavorful than the wild strawberries native to the region. They were known as “scarlet strawberries” and were introduced by French settlers in the 17th century.
4. The size of strawberries can be influenced by factors such as plant variety, weather conditions, and even bee activity. Lack of pollination can result in smaller strawberries, so having a diverse range of pollinators in your garden can help produce larger fruits.
5. To make strawberries appear larger, some commercial growers use the technique of forcing fruit enlargement by exposing the plants to high levels of carbon dioxide. This process, known as carbon dioxide supplementation, is done in greenhouses to create larger strawberries for market.
Factors Affecting Strawberry Size And Yield
When it comes to growing strawberries, achieving large and juicy fruits is a top priority for farmers and gardeners. However, various issues can cause strawberries to be small or deformed, significantly affecting their marketability and yield.
Several factors contribute to the size and quality of strawberries, including:
- Poor pollination: Strawberries have multiple ovules per fruit that need to be pollinated in order for the fruit to develop fully. Therefore, better pollination leads to larger fruit. Pollinators such as honeybees, bumblebees, native bees, and many species of flies play a vital role in strawberry pollination. Ensuring the presence of these pollinators in your strawberry patch can significantly increase fruit size and yield.
- Tarnished plant bug damage: This pest can cause deformities and feeding damage to strawberries, resulting in smaller fruits. Implementing pest control measures, such as regular scouting and appropriate insecticide treatments, can help prevent or reduce the damage caused by these bugs.
- Frost damage: Exposure to freezing temperatures can have a negative impact on strawberry size and quality. To minimize frost damage, it is important to choose appropriate planting dates and provide adequate frost protection, such as row covers or overhead sprinklers, when needed.
- Weed pressure: Competition from weeds can hinder the growth and development of strawberry plants, leading to smaller fruits. Implementing effective weed control strategies, such as mulching and regular cultivation, can help reduce weed pressure and promote better fruit size.
- Old plantings: As strawberry plants age, their productivity tends to decline, resulting in smaller fruits. It is recommended to renovate or replant strawberry beds every few years to maintain optimal plant vigor and maximize fruit size.
- Anthracnose infection: This fungal disease can cause fruit rot and deformities in strawberries, leading to reduced size and quality. Proper sanitation practices and fungicide applications can help prevent and manage anthracnose in strawberry crops.
- Poor nutrient management: Inadequate or imbalanced nutrient levels can affect the size and overall health of strawberry plants. Conducting regular soil testing and providing appropriate fertilization based on the specific nutrient requirements of strawberries can help optimize fruit size and quality.
- Dry soil: Insufficient moisture can hinder strawberry growth and result in smaller fruits. Adequate irrigation and mulching can help maintain proper soil moisture levels and promote better fruit development.
By addressing these factors and implementing appropriate management practices, growers and gardeners can improve the size and quality of their strawberries, ultimately enhancing their marketability and yield.
Importance Of Pollinators In Strawberry Production
Pollinators are essential for the successful production of strawberries. These tiny creatures are responsible for transferring pollen from the male parts of the strawberry plant to the female parts, which leads to fruit development. Without proper pollination, strawberries can be small, misshapen, or fail to develop entirely.
Encouraging a diverse pollinator population in your strawberry patch is crucial. Providing a variety of flowering plants and creating a suitable habitat can attract pollinators such as bees and flies. Additionally, avoiding or reducing the use of harmful insecticides during strawberry bloom can also help protect pollinators and ensure successful pollination. The presence of these pollinators will result in larger, juicier strawberries that are both visually appealing and have enhanced flavor.
Tarnished Plant Bug: A Threat To Strawberry Fruit Size
The tarnished plant bug (TPB) is a common insect pest that can severely impact strawberry fruit size. TPB damage is particularly noticeable at the tip of the berry, where it can cause significant deformation and reduce overall fruit size.
To prevent the negative effects of TPB, it is crucial to scout for TPB activity before bloom and apply appropriate insecticides at regular intervals.
Distinguishing damage caused by TPB from frost damage is important for effective management. Frost damage during bloom can result in deformed fruit with a concentration of seeds on the affected portion. In contrast, TPB damage typically exhibits deformities at the tip, and scouting usually reveals the presence of these pests.
By properly identifying the cause of small strawberries, growers can take appropriate action to mitigate the issue and promote healthy fruit size.
- Scout for TPB activity before bloom
- Apply appropriate insecticides regularly
- Distinguish between TPB damage and frost damage
- Identify the cause of small strawberries
“The tarnished plant bug, or TPB for short, is a common insect pest that can severely impact strawberry fruit size.”
Managing Frost Damage And Weed Pressure In Strawberries
Frost damage during strawberry bloom is a significant factor that can result in small or deformed fruit. The freezing temperatures can cause harm to the delicate blossoms, leading to abnormalities in the fruit and reduced overall yield. To minimize the risk of frost damage, it is highly recommended to implement preventive measures such as using row covers or irrigation techniques that create a protective layer of ice around the plants.
Additionally, weed pressure is another crucial issue that affects strawberry size and yield. Weeds compete with the strawberry plants for essential resources like sunlight, water, and nutrients. It is imperative to maintain good weed control throughout the entire season by regularly removing weeds and implementing appropriate weed management strategies. By doing so, the strawberries can grow without unnecessary competition and reach their full potential in size and quality.
- Implement preventive measures like row covers or irrigation techniques to protect against frost damage.
- Regularly remove weeds and maintain good weed control throughout the entire season.
- Ensure strawberries have access to essential resources (sunlight, water, and nutrients) by managing weed pressure effectively.
Nutrient Management For Larger And Healthier Strawberries
Proper nutrient management is essential for achieving larger and healthier strawberries. Strawberries require a balanced supply of nutrients, including nitrogen, phosphorus, potassium, boron, and calcium, to support their growth and fruit production. Insufficient levels of these nutrients in the soil or the plants’ inability to absorb them can result in small fruit size.
To prevent nutrient deficiencies, it is recommended to conduct soil testing before planting a new strawberry field. This allows growers to determine the nutrient content of the soil and make any necessary adjustments before planting. Additionally, leaf samples should be collected and analyzed each season to monitor nutrient levels throughout the growing period and make appropriate fertilization decisions.
Practicing good renovation, disease management, fertility, and weed management is crucial for maintaining the health and productivity of strawberry beds. It is also advisable to rotate the field into a cover crop or an alternative field crop, such as pumpkins, for at least two seasons before replanting strawberries. This rotation helps break disease and pest cycles and ensures the soil remains fertile and conducive to growing large, robust strawberries.
By understanding the various factors contributing to small strawberries and implementing appropriate management practices, growers can improve fruit size, marketability, and overall yield.
Practical tips:
- Conduct soil testing before planting.
- Collect and analyze leaf samples each season.
- Practice good renovation, disease management, fertility, and weed management.

Frequently Asked Questions
How do you increase the size of strawberries?
To increase the size of strawberries, it is crucial to provide day-neutral varieties with a consistent nitrogen rate throughout the planting year. Applying 1 pound of ammonium nitrate per 100 feet of row once a month from June to September helps maintain steady growth. Additionally, strategic irrigation plays a vital role in enlarging the berries. By providing timely irrigation as the berries develop, strawberry size can be significantly increased, resulting in more bountiful fruits.
What causes strawberries to be small and seedy?
The size and seediness of strawberries can be attributed to inadequate pollination. When strawberries do not receive proper pollination, their seeds fail to trigger the growth of the surrounding berry. As a result, the fruit remains small and seedy, indicating that the flowers were not effectively pollinated, impeding their growth.
What is the best fertilizer for strawberries?
Strawberries thrive on a balanced diet, making a 10-10-10 or 12-12-12 fertilizer an excellent choice. These balanced fertilizers provide essential nutrients in equal proportions, ensuring optimal growth and fruit production.
