Should You Trim Strawberry Plants This Fall? Expert Insights on Winter Care

As fall approaches, strawberry plants can start to look untidy. After a fruitful summer filled with blooms and berries, your strawberry patch might be cluttered with old leaves and an abundance of runners.

Whether your strawberries thrive in the ground, raised beds, or containers, the urge to grab the shears for a tidy-up can be strong. However, is it truly advisable to trim back strawberry plants in the fall?

While autumn presents a suitable opportunity to propagate new plants by removing runners, cutting back strawberries too much can jeopardize their health and impair future yields.

Is Trimming Strawberry Plants Necessary for Winter?

To determine the best approach, we consulted several experts on what to trim and what to leave alone on established strawberry plants during fall. While early to mid-fall might be the right time to plant strawberries, it's crucial not to prune new plants before winter.

Should You Cut Back Strawberries in Fall?

Strawberries are resilient in U.S. hardiness zones 6 and higher, but they may still need some protection, such as horticultural fleece or a layer of straw mulch, especially in colder climates. A key risk of excessive fall pruning is exposing the crown of the plants to cold and frost during winter. This is particularly concerning in colder hardiness zones.

'We strongly advise against pruning these plants just before winter,' cautions Lotte Berendsen, a certified botanist associated with the PlantIn app. 'If frost occurs soon after pruning, the cold can severely damage the plant tissue.

'Moreover, healthy leaves serve as a protective layer for fresh growth in early spring.'

There are various types of strawberry plants, including summer-fruiting and fall-bearing varieties. Summer-fruiting types should be trimmed down to about three inches high post-harvest in late summer, whereas fall-bearing varieties benefit from light trimming after cropping.

'For fall-bearing strawberries, prune only to eliminate dead or diseased leaves around September or October to prevent diseases,' recommends Lotte Berendsen. 'Avoid cutting these plants down to the crown; doing so risks losing future fruits.'

Pruning summer-fruiting strawberries in the fall can be a critical mistake, as it jeopardizes the next year's crop and exposes the tender crown to freezing temperatures. Trimming fall-fruiting varieties too early deprives them of the chance to produce late-season fruit.

Leaving the foliage intact over winter can shield the strawberry crown from freezing and rot. In fact, a heavy fall trim of any strawberry type heightens the likelihood of damage from harsh winter weather, even with mulch in place. It's best to retain all healthy, green leaves while focusing on removing only the dead, brown ones.

Gently trimming dead or diseased leaves in fall can help manage fungal and bacterial strawberry diseases and ensures the plants are primed for vigorous growth in the spring. Lindsey Chastain, CEO of Waddle and Cluck, adds that removing such foliage also helps deter strawberry pests. She notes: 'Eliminating dead leaves minimizes habitats where pests may settle for the winter.'

Any trimming of strawberry plants in fall should be done with caution to prevent damage to the central crown. A pair of sharp, clean pruning shears is ideal for targeting and removing infected or dead leaves, which should then be discarded away from the strawberry bed. Diseased leaves should be bagged and disposed of instead of composted.

FAQs

Should Everbearing Strawberries Be Cut Back in Fall?

Everbearing strawberries yield crops in late spring and again in late summer or early fall. The best time to prune them is in spring, so trimming them in fall is not advisable.

Any mulching to prepare strawberry plants for winter should occur before the first ground frosts. Lindsey Chastain recommends avoiding dense materials that may retain excess moisture around the crowns. Straw or pine needles are better options than compost or leaf mulch.
