When to Plant Strawberries in Delaware (2026 Guide)
Strawberries are a delightful perennial that can provide fresh fruit for several years when properly cared for. In Delaware, frost dates dictate the best times for planting to ensure a successful harvest. For those in Zone 6b, the last spring frost falls on April 9, while in Zone 6a, it occurs on April 18. Understanding these dates is crucial to planning your strawberry garden effectively.
Planting strawberries can be a rewarding endeavor. They thrive in regions with a frost-free season, approximately 204 days in Zone 6b and 189 days in Zone 6a. During this time, strawberries can produce a bountiful crop, especially if you choose the right variety. June-bearing, everbearing, and day-neutral types each have unique benefits, with day-neutral varieties providing continuous harvests throughout the growing season.
To achieve the best results, strawberry crowns should be planted at the soil level to avoid rot or drying out. Proper mulching and renovation will help these plants thrive year after year. With attention to planting windows and care, gardeners in Delaware can enjoy a rich supply of sweet strawberries right from their backyards.

Common Mistakes Growing Strawberries in Delaware
- One of the most frequent mistakes Delaware gardeners make is planting strawberry crowns too deep. The crown should be at soil level; burying it can cause rot, while exposure can lead to drying out.
- Many new strawberry growers in Delaware overlook the importance of managing runners in their beds. Allowing too many runners to grow the first year can hinder root development and reduce overall yield.
- Delaware's humidity can lead to complications like gray mold. It's essential to give strawberries adequate spacing for air circulation and avoid overcrowding with larger plants that can trap moisture.
- Some gardeners mistakenly plant strawberries in areas with poor drainage. Given Delaware's occasional heavy rainfall, this can lead to root rot and disease, undermining plant health.
- Ignoring the renovation process of June-bearing strawberries can hurt future yields. Properly mowing and caring for plants after harvest is vital for preparing them for the next growing season.
Frequently Asked Questions
What if I'm in a colder pocket of Delaware?
If you're in a colder area, consider starting your bare-root crowns a bit later in the transplant window to avoid frost damage. Observing local frost dates closely is crucial.
Can I still plant strawberries in May?
Planting in May is not ideal due to the increased risk of pests and diseases. It's best to stick to the March or September transplant windows for optimum results.
Can I plant strawberries in partial shade?
While strawberries can tolerate some shade, they thrive best in full sun. Aim for at least six hours of sunlight daily for a successful harvest.
Is it worth it to plant strawberries from seed?
Technically, strawberries can be grown from seed but it’s generally not practical for home gardeners. It's more efficient to buy bare-root crowns or plugs from a nursery.
When should I renovate my June-bearing strawberry beds?
Renovation should occur immediately after harvest. This involves mowing the plants back to 2-3 inches, thinning runners, and applying fertilizer to help them grow back stronger.
