Growing strawberries in Michigan is a rewarding endeavor for any home gardener. The Great Lakes State offers a climate that, while challenging in winter, is ideal for producing sweet and juicy berries during the spring and summer months. Michigan’s sandy-loam soils and distinct seasons provide the perfect environment for several high-performing strawberry varieties. Whether you are a beginner or an experienced gardener, following a few specific steps will ensure a bountiful harvest.
Selecting the Right Varieties for Michigan
The first step in a successful strawberry patch is choosing the right cultivar. In Michigan, gardeners generally choose between two main types of strawberries: June-bearing and everbearing (including day-neutral) varieties.
June-bearing strawberries are the most popular choice for Michigan gardens. These plants produce one large crop over a period of two to three weeks, typically in June. They are known for having the largest fruit and the best flavor for preserves and freezing. Recommended June-bearing varieties for Michigan include:
- Earliglow: Known for its exceptional flavor and early ripening.
- Honeoye: A very hardy variety that produces large, firm berries.
- Jewel: Excellent for fresh eating and resistant to many common diseases.
- Allstar: A mid-to-late season berry that is highly resistant to verticillium wilt.
Everbearing and day-neutral varieties produce fruit throughout the growing season. While the berries are often smaller than June-bearing types, they provide a consistent supply of fresh fruit from June until the first hard frost. Popular choices include Albion, Seascape, and Tribute. These are ideal for small spaces or container gardening.
Site Selection and Soil Preparation
Strawberries require full sun to thrive. You should select a site that receives at least six to eight hours of direct sunlight daily. Good air circulation is also vital to prevent fungal diseases, but the site should have some protection from harsh winds.
Soil quality is the foundation of a healthy strawberry plant. Strawberries prefer well-drained soil rich in organic matter. Sandy or gravelly loam is ideal. If your garden has heavy clay soil, consider planting in raised beds to improve drainage. The optimal soil pH for strawberries is between 5.5 and 6.8. You can test your soil through a local MSU Extension office to determine if you need to add sulfur to lower the pH or lime to raise it.
Avoid planting strawberries in areas where you have recently grown tomatoes, potatoes, peppers, or eggplants. These crops can leave behind verticillium wilt, a soil-borne fungus that can devastate strawberry plants.
Planting and Spacing
In Michigan, the best time to plant strawberries is in early spring, as soon as the soil can be worked. This is usually in late March or April. Planting early allows the roots to establish themselves before the heat of summer arrives.
When planting, pay close attention to the depth. The crown of the plant—the point where the roots meet the leaves—should be level with the soil surface. If you bury the crown, it will rot. If you leave the roots exposed, the plant will dry out and die.
The matted row system is the most common planting method for June-bearing varieties. Space your plants 18 to 24 inches apart in rows that are 3 to 4 feet apart. This allows the plants to send out “runners” (horizontal stems) that will fill in the gaps and create a thick mat of plants. For everbearing types, the hill system is often preferred, where plants are spaced 12 inches apart and all runners are removed to focus energy on fruit production.
Essential Care and Maintenance
Proper maintenance is the difference between a few berries and a massive harvest. During the first growing season for June-bearing plants, you should pinch off all flowers. This might be difficult for a gardener to do, but it is necessary. Removing the flowers prevents the plant from fruiting early, forcing it to put all its energy into developing a strong root system and runners for the following year.
Watering is critical, especially during fruit development. Strawberries need about one inch of water per week. In sandy Michigan soils, you may need to water every two to three days during dry spells. Always try to water at the base of the plant to keep the foliage dry, which helps prevent leaf spot and fruit rot.
Fertilize your plants in early spring when growth begins. A balanced fertilizer like 10-10-10 is generally sufficient. For June-bearing types, fertilize again in July after the harvest is complete. This helps the plants “renovate” and prepare for next year’s buds.
Protecting Your Plants Through Michigan Winters
Winter protection is mandatory in Michigan. Temperatures below 20 degrees Fahrenheit can damage or kill the flower buds and crowns. Once the ground has frozen—usually in late November or early December—apply a 3-to-4-inch layer of clean straw over the plants.
Do not use leaves or grass clippings, as these tend to mat down and can smother the plants. In early spring, when you see the first signs of new green growth or yellow leaves under the mulch, rake the straw off the plants and into the rows. Leaving the straw in the aisles helps keep the berries clean and suppresses weeds during the growing season.
FAQs About Growing Strawberries in Michigan
When is the best time to plant strawberries in Michigan? The ideal time is early spring, typically late March or April, as soon as the soil is no longer muddy and can be easily worked.
How many strawberry plants do I need for a family of four? For a steady supply of fresh berries and enough for some light jam-making, aim for about 25 to 30 plants per person, or roughly 100 to 120 plants total.
Why should I remove the flowers during the first year? Removing flowers on June-bearing plants during the first year allows the plant to focus on root and runner development. This leads to a much larger and healthier crop in the second and third years.
What is the best mulch for Michigan strawberries? Clean wheat or oat straw is the best mulch. It provides excellent insulation in the winter and helps keep fruit off the damp soil in the summer.
How long will a strawberry patch last? A well-maintained strawberry patch typically remains productive for three to four years. After this time, the plants often become crowded and disease-prone, and it is best to start a new patch in a different location.
