Growing your own strawberries is one of the most rewarding experiences for any gardener. There is a significant difference between the flavor of a store-bought berry and one ripened by the sun in your own backyard. Starting a strawberry plant is relatively simple, but it requires attention to detail and proper timing to ensure a bountiful harvest. Whether you have a sprawling garden or a small balcony, strawberries are versatile enough to thrive in many environments.
Choosing the Right Variety
Before you put a single root into the soil, you must decide which type of strawberry fits your needs. There are three main categories of strawberry plants. Each has a different fruiting cycle and growth habit.
June-Bearing Strawberries
Produce one large crop over a period of two to three weeks, typically in June. These are excellent if you want a large volume of berries at once for jam or freezing. They produce many runners and require a bit more space to spread.
Ever-Bearing Strawberries
Produce two to three harvests throughout the summer and fall. They do not produce as many runners as June-bearing types. These are perfect for small gardens where you want a steady supply of fruit over several months.
Day-Neutral Strawberries
Are modern hybrids that produce fruit consistently throughout the growing season as long as temperatures remain between 35°F and 85°F. They produce very few runners and are ideal for containers or raised beds.
Selecting the Best Location
Strawberries are sun-loving plants. To produce sweet, juicy berries, they need at least six to eight hours of direct sunlight every day. If they are planted in the shade, you will get plenty of green leaves but very little fruit.
The soil is the next critical factor. Strawberries prefer well-draining soil with a slightly acidic pH between 5.5 and 6.8. If your soil consists of heavy clay, consider planting in raised beds or containers to improve drainage. Soggy soil often leads to root rot, which can quickly kill a young plant.
Avoid planting strawberries in areas where you have recently grown tomatoes, potatoes, peppers, or eggplants. These plants can carry verticillium wilt, a soil-borne disease that is devastating to strawberries.
Preparing the Soil
Once you have chosen your spot, clear away any weeds or grass. These competitors will steal nutrients and water from your strawberries. Incorporate plenty of organic matter, such as aged compost or well-rotted manure, into the top six inches of soil. This improves the soil structure and provides a slow-release source of nutrients.
If you are planting in containers, use a high-quality potting mix. Avoid using garden soil in pots because it compacts too easily and prevents oxygen from reaching the roots.
Planting Techniques
Most gardeners start strawberries from bare-root plants or small potted transplants. Bare-root plants look like a dried bundle of roots with a tiny bit of green at the top. Before planting these, soak the roots in a bucket of water for about 20 minutes.
The most important rule when planting strawberries is the depth of the crown. The crown is the thick, woody part where the roots meet the leaves. If you plant the crown too deep, it will rot. If you plant it too high, the roots will dry out. Aim to set the plant so the soil level is exactly at the midpoint of the crown.
Space June-bearing plants about 18 inches apart in rows. Ever-bearing and day-neutral varieties can be planted closer together, roughly 10 to 12 inches apart. Spread the roots out in a fan shape as you place them in the hole to encourage outward growth.
Initial Care and Maintenance
After planting, water your strawberries thoroughly. The first few weeks are critical for root establishment. Keep the soil consistently moist but not waterlogged. Adding a layer of straw or pine needle mulch around the plants helps retain moisture, suppresses weeds, and keeps the developing fruit off the dirt.
For June-bearing plants, many experts recommend pinching off all blossoms during the first year. This feels counterintuitive to a new gardener. However, removing the flowers forces the plant to put its energy into building a strong root system and healthy runners. This sacrifice leads to a much larger harvest in the second year. For ever-bearing and day-neutral plants, remove flowers only until early July, then allow them to fruit for the remainder of the season.
Watering and Fertilizing
Strawberries have shallow root systems. They cannot reach deep into the earth for water during dry spells. They generally need about an inch of water per week. During the heat of summer, you may need to water more frequently. Always water at the base of the plant. Wetting the leaves can encourage fungal diseases like powdery mildew or leaf spot.
Fertilize your plants in early spring and again after the final harvest of the season. Use a balanced fertilizer, such as a 10-10-10 formula. Avoid over-fertilizing with nitrogen, as this will result in lush green growth but very few berries.
Managing Runners
As the season progresses, your strawberry plants will send out “runners.” These are long stems that grow along the ground and sprout new baby plants. While this is how strawberries propagate, too many runners can lead to overcrowding. If the plants become too crowded, the berries will be small and air circulation will decrease, leading to disease.
In a “matted row” system, you allow some runners to root within a specific area. In a “hill” system, typically used for ever-bearing types, you cut off all runners to keep the mother plant strong and productive.
Harvesting Your Strawberries
The moment of harvest is the highlight of the process. Strawberries do not continue to ripen after they are picked. Wait until the berry is fully red from the tip to the shoulder. Pick them in the morning when the fruit is still cool. Instead of pulling the berry, which can damage the delicate plant, use your fingernails or shears to snip the stem just above the fruit.
Winter Protection
In colder climates, strawberry plants need protection during the winter. Once the ground has frozen and the plants are dormant, cover them with three to four inches of clean straw. This prevents “frost heaving,” where the freezing and thawing of the soil pushes the plants out of the ground. In the spring, when you see new green growth beginning to emerge, rake the straw away and move it to the aisles between rows.
Frequently Asked Questions
-
Can I grow strawberries in pots? Yes, strawberries are excellent for containers. Use a pot with good drainage and a high-quality potting mix. Day-neutral varieties are usually the best choice for small containers or hanging baskets.
-
How long does it take for a strawberry plant to produce fruit? Most June-bearing plants provide a full harvest in their second year. Ever-bearing and day-neutral varieties can produce a small crop in their first year, especially if you stop removing blossoms by mid-summer.
-
Why are my strawberries small and sour? Small berries often result from a lack of water or poor soil nutrients. Sour berries are usually the result of picking the fruit before it is fully ripe or a lack of sufficient sunlight during the ripening process.
-
Do strawberry plants come back every year? Strawberries are perennials, meaning they will return for several years. However, their productivity usually declines after three to five years. Most gardeners replace their plants or start new ones from runners every few seasons to keep the harvest high.
-
What is eating my strawberries? Birds, slugs, and squirrels are the most common culprits. You can protect your crop by using bird netting or elevated containers. For slugs, organic baits or copper tape around the edges of raised beds can be effective.
