Growing your own strawberries is one of the most rewarding projects a gardener can undertake. There is a significant difference in flavor between a store-bought berry and one ripened by the sun in your own backyard. Strawberries are hardy, versatile, and relatively easy to maintain once you establish the patch. This guide provides a comprehensive roadmap for successfully planting and nurturing strawberries in your home garden.
Choosing the Right Strawberry Variety
Before you dig your first hole, you must select the variety that best fits your needs. Not all strawberries are the same. They are generally categorized into three main types based on their fruiting habits.
June-bearing varieties produce one large crop per year, usually over a period of two to three weeks in early summer. These are ideal if you want a large harvest all at once for making jams or freezing. Popular varieties include ‘Allstar’ and ‘Jewel’.
Ever-bearing varieties produce two to three flushes of fruit during the growing season. You will typically see a harvest in the spring, a smaller one in summer, and another in the fall. They are great for consistent snacking throughout the warmer months. ‘Fort Laramie’ is a well-known ever-bearing choice.
Day-neutral varieties are the most modern hybrids. They are insensitive to day length and will produce fruit continuously throughout the summer as long as temperatures remain between 35°F and 85°F. ‘Albion’ and ‘Seascape’ are excellent day-neutral options for home gardens.
Selecting the Perfect Planting Site
Strawberries are sun-loving plants. To ensure high yields and sweet fruit, choose a location that receives at least six to eight hours of direct sunlight every day. Sunlight is the primary driver of sugar production in the berries.
Drainage is the second most important factor. Strawberries have relatively shallow root systems and are prone to root rot if they sit in waterlogged soil. If your garden has heavy clay or stays damp after rain, consider planting in raised beds. Raised beds allow you to control the soil quality and ensure proper drainage.
Avoid planting strawberries in areas where you have recently grown tomatoes, peppers, potatoes, or eggplants. These plants can carry verticillium wilt, a soil-borne fungus that can devastate a new strawberry patch.
Preparing the Soil
Strawberries thrive in slightly acidic soil with a pH between 5.5 and 6.8. You can test your soil with a simple home kit. If your soil is too alkaline, you can add elemental sulfur to lower the pH. If it is too acidic, garden lime will help raise it.
Enrich the soil with organic matter several weeks before planting. Work in two to three inches of well-composted manure or garden compost. This improves soil structure and provides a slow-release source of nutrients. Strawberries are heavy feeders, so starting with nutrient-rich soil is essential for a healthy crop.
When and How to Plant
The best time to plant strawberries is in the early spring as soon as the soil can be worked. This gives the plants time to establish their root systems before the heat of summer arrives. In warmer climates, some gardeners plant in the fall to allow for a spring harvest.
When you are ready to plant, follow these steps for the best results:
- Dig the hole: Make sure the hole is deep and wide enough to accommodate the entire root system without crowding.
- Check the depth: This is the most critical part of strawberry planting. You must set the plant so that the “crown” is exactly at the soil surface. The crown is the thick woody part where the leaves emerge. If you bury the crown, the plant will rot. If the crown is too high, the roots will dry out.
- Spread the roots: Fan the roots out downward in the hole rather than leaving them in a tight ball.
- Firm the soil: Fill the hole with soil and press down firmly with your hands to remove air pockets.
- Water immediately: Give the new plants a generous soak to help settle the soil around the roots.
Spacing and Planting Systems
How you space your plants depends on the variety you chose.
For June-bearing strawberries, the matted row system is common. Space plants about 18 inches apart in rows that are 3 to 4 feet apart. These plants will produce “runners,” which are long stems that grow along the ground and sprout new baby plants. You allow these runners to fill in the space to create a thick mat of berries.
For ever-bearing and day-neutral types, the hill system is often preferred. Space plants 12 inches apart in double or triple rows. In this system, you remove all runners. This forces the plant to put all its energy into producing fruit rather than new plants.
Ongoing Care and Maintenance
Once planted, strawberries require consistent attention to produce the best fruit.
- Watering: Strawberries need about one inch of water per week. This is especially important during the fruiting season and when the runners are developing. Always water at the base of the plant to keep the leaves and fruit dry. This helps prevent fungal diseases like powdery mildew or fruit rot.
- Mulching: Apply a layer of clean straw or pine needles around the plants. This serves multiple purposes. It keeps the fruit off the soil, which prevents rot and keeps the berries clean. It also suppresses weeds and helps the soil retain moisture.
- Fertilizing: Apply a balanced fertilizer in early spring and again after the final harvest of the season. Avoid over-fertilizing with nitrogen during the fruiting period, as this can lead to excessive leaf growth and soft, flavorless berries.
- Weeding: Keep the patch free of weeds. Because strawberries are shallow-rooted, weeds can easily steal the nutrients and moisture your berries need. Hand-pulling is the safest method to avoid damaging the strawberry roots.
Harvesting Your Strawberries
Strawberries are usually ready for harvest four to six weeks after blossoming. Only pick berries that are fully red. Unlike some fruits, strawberries do not continue to ripen or get sweeter once they are picked.
Harvest in the cool of the morning if possible. This helps the berries stay firm and last longer. Always leave the green cap and a small bit of the stem attached to the berry to prevent the fruit from bruising or drying out.
Frequently Asked Questions
- How many strawberry plants should I plant per person? For a fresh supply of berries throughout the season, aim for about 5 to 10 plants per person in your household. If you plan on canning or making jam, you may want to plant 20 to 25 plants per person.
- Do I need to replace my strawberry plants every year? No, strawberries are perennials. However, their productivity usually declines after three or four years. Most gardeners rotate their patch or replace plants every three years to keep the harvest high.
- Should I cut off the flowers in the first year? For June-bearing plants, it is recommended to pinch off all flowers during the first growing season. This encourages the plant to focus on root and runner development, leading to a much larger harvest the following year. For ever-bearing types, remove flowers only until early July.
- What is eating holes in my strawberries? Slugs and snails are the most common culprits. They love the moist environment under the leaves. Using straw mulch helps, but you may also need to use organic slug bait or copper tape if the infestation is heavy. Birds can also be a problem; bird netting is the most effective way to protect your ripening fruit.
- Can I grow strawberries in containers? Yes, strawberries are excellent candidates for containers, hanging baskets, or “strawberry pots.” Ensure the container has plenty of drainage holes and use a high-quality potting mix. Since containers dry out faster than the ground, you will need to water them more frequently.
