Growing Strawberries in Zone 4B

Strawberries are the most popular home fruit crop for good reason — fresh-picked berries are incomparably sweeter than anything from a store.

Zone 4B has a short growing season — start seeds indoors when possible and use season-extending techniques like cold frames and row covers.

Top Growing Tips

• Plant bare-root crowns in early spring (2-4 weeks before last frost) or in fall in zones 6+
• Keep the crown (where roots meet leaves) at soil level — too deep rots, too shallow dries out
• June-bearing types give one big harvest; everbearing produce all season
• Remove blossoms the first year to build root strength and get bigger harvests in year 2+
• Renovate beds every 3-4 years by thinning runners to maintain vigor
• Mulch with straw in fall (zones 5 and colder) to protect crowns from freeze-thaw cycles

Companion Planting

Good companions: spinach, lettuce, thyme, sage, borage (said to improve flavor)

Avoid planting near: brassicas, fennel, kale (can harbor pests that transfer)

Harvest Timeline

Harvest when fully red with no white shoulders; check plants every 1-2 days at peak
