Genetic Expression of Strawberry Varieties
The genetic expression of different strawberry varieties plays a significant role in determining the size of the fruits they produce. Various strawberry varieties are available, each with its unique characteristics.
June-bearing strawberries are the most common varieties in grocery stores and farmer’s markets. These strawberries are known for their large berries, making them visually appealing and perfect for various culinary uses.
However, other strawberries, such as heirloom strawberries or “true species” varieties, naturally produce small yet intensely flavorful strawberries through pollination. These include Alpine strawberries and Wild strawberries, which strawberry enthusiasts have enjoyed for generations.
Suppose you’ve noticed small strawberries in your garden that still have a remarkable aroma and flavor without any signs of pests or pathogens. In that case, you may have a healthy “true species” of Fragaria, such as Vesca or Virginiana.
Understanding the genetic expression of different strawberry varieties can help you appreciate the diverse range of fruits they can produce, from large and visually striking berries to small but incredibly delicious ones.
Explore the world of strawberries and consider experimenting with different varieties to discover your favorites. Whether you prefer larger berries that make a statement or smaller strawberries bursting with intense flavor, a strawberry variety suits your preferences and gardening goals.
“Remember, the genetic expression of strawberry varieties is just one factor contributing to the size and flavor of the berries. Other factors, such as growing conditions, care, and environmental factors, also play important roles in the overall quality of your strawberries.” – Tracy Langell, horticulturist and sustainable gardening specialist.
Heat and Drought Stress
Heat and drought stress can significantly impact the size of strawberries. These herbaceous forbs require water for both their growth and maintaining their shape through turgor pressure. When strawberry plants become dehydrated, they wilt, resulting in smaller berries.
Strawberries are temperate plants that thrive in moderate temperatures, making them less tolerant of extreme heat. The stress caused by inadequate mulching and high temperatures can diminish strawberry size.
Inadequate water availability during heat or drought conditions can also contribute to producing small strawberries. Even if they are red, strawberries lacking proper water requirements may lack the flavor and sweetness of larger strawberries.
Therefore, it is crucial to ensure that strawberries receive adequate care and that strawberry plants receive sufficient water, especially during high temperatures and drought stress.
Effects of Heat and Drought Stress on Strawberry Size
Heat stress and drought stress impact strawberries in multiple ways. Firstly, inadequate water availability affects the plant’s ability to uptake nutrients and minerals from the soil.
This nutrient deficiency can hinder the growth and development of the berries, resulting in smaller sizes and suboptimal flavor.
Secondly, high temperatures can alter the physiological processes of strawberry plants, disrupting vital metabolic pathways that contribute to fruit development.
The increased stress brought about by elevated temperatures can also negatively affect the photosynthesis rate, ultimately impacting the size and quality of the strawberries.
To better understand the effects of heat stress, researchers at the University of California, Davis, conducted a study comparing the fruit quality of strawberry plants under different temperature regimes.
They found that strawberries grown at higher temperatures had decreased size, lower sugar content, and diminished flavor than those grown under moderate temperature conditions.
“The study highlights the importance of providing optimal growing conditions for strawberry plants to achieve desirable fruit size and flavor. Heat stress and drought stress can compromise the development and taste of strawberries, emphasizing the need to prioritize appropriate watering practices and temperature control to ensure larger, flavorful berries.”– Tracy Langell, horticulturist and sustainable gardening specialist.
Managing heat and drought stress requires careful attention to watering practices, soil moisture monitoring, and providing shade or cooling methods during extreme heatwaves.
Ideally, you should water your strawberries when the top two inches of soil become dry or if there’s less than an inch of rainfall a week (to learn more about watering strawberries, read here).
Water your strawberries in the morning or early afternoon to allow them to dry before nightfall. Your soil should be consistently moist, but avoid making it boggy.
By understanding and mitigating the impact of heat and drought stress, strawberry growers can improve the size and flavor of their harvest.
Cold Stress
Heat isn’t the only problem. If your environment is too cold, your strawberry plant may start producing small berries. This is particularly true in late spring when frosts and cold snaps can deform the fruit’s shape and produce darker centers.
Insulate your strawberries to preserve them, but remember to uncover them during the day so they can be pollinated.
Inadequate Pollination
Strawberries are delightful fruits known for their juicy and sweet flavor. However, their size can vary depending on the pollination process.
Pollination plays a crucial role in determining strawberries’ maximum size. Inadequate pollination can lead to small strawberries that fail to reach their full potential.
Various factors, such as excessive rain, prolonged periods of high wind, and cold weather, can contribute to poor pollination.
These conditions can hinder the activity of insects and bees, essential strawberry pollinators. The pollination process is compromised without their assistance, resulting in small strawberries.
Creating a pollinator-friendly environment where your strawberry plants can access favorable weather conditions and pollinate is crucial.
Creating an environment that attracts bees and other beneficial insects can help promote proper pollination. Here are some steps you can take:
- Plant flowers that attract pollinators, such as lavender, borage, and bee balm, near your strawberry patch.
- Provide a water source for bees to help keep them hydrated and encourage their presence.
- Avoid using pesticides that are harmful to bees and other pollinators.
Creating a pollinator-friendly environment can increase the chances of adequate pollination, resulting in larger and more luscious strawberries. Proper pollination is essential when you grow strawberries.
Preventing Poor Pollination Due to Rain, Wind, and Cold Weather
Excessive rain, high wind, and cold weather can significantly impact pollination. These factors can discourage insect and bee activity, leading to poor pollination and small strawberries. To mitigate these challenges, consider the following tips:
- Provide shelter for your strawberry plants during heavy rain and wind. Row covers or makeshift structures can protect the plants without obstructing airflow.
- Choose strawberry varieties that are more tolerant of cold weather, especially if you live in a region with chilly springs or early frosts.
- Consider using techniques such as hand pollination or bumblebee hives to supplement natural pollination efforts during unfavorable weather conditions.
Implementing these strategies can minimize the negative impact of rain, wind, and cold weather on pollination, leading to better strawberry size and quality.

Excessive Foliage, Weeds and Overcrowding
Excessive foliage on strawberry plants can significantly impact strawberry size and quality. When the foliage becomes excessive, it can create a dense canopy that inhibits pollination.
Insects, such as bees, may have difficulty locating the flowers, thus reducing the chances of successful pollination. This ultimately leads to smaller strawberries.
Overcrowding of strawberry plants can also contribute to smaller berry size. When there are too many plants in a confined space, they compete for resources like sunlight and nutrients, limiting their growth potential.
Overcrowding can result in poor air circulation, which creates a moist environment that encourages disease development.
Proper weed control and runner management are essential to combat excessive foliage and overcrowding. Weeds can quickly take over and crowd out the strawberry plants, so regular weeding is crucial to minimize competition for resources.
Additionally, managing runners by removing or redirecting them can help maintain an appropriate plant density, allowing each plant to thrive and produce larger strawberries.
Effect of Nitrogen on Foliage Growth
Nitrogen is an essential nutrient for plant growth and development. It plays a vital role in promoting lush foliage growth in strawberry plants.
While foliage is necessary for photosynthesis and overall plant health, excessive nitrogen can lead to an overabundance of foliage and negatively impact fruiting, resulting in smaller fruit.
“Excessive foliage growth, caused by high amounts of nitrogen, can hinder pollination. It becomes more challenging for insects to navigate through the dense foliage and locate the flowers for pollination, resulting in smaller strawberries.” – Tracy Langell, horticulturist and sustainable gardening specialist.
Therefore, it’s crucial to manage nitrogen levels appropriately by using a balanced fertilizer and following recommended application rates.
This helps ensure the optimal balance between foliage growth and fruit development, ultimately leading to larger and more flavorful strawberries.
