How to Grow and Maintain Your Grass in Winter

by Joshua Pearson October 15, 2025

When temperatures drop and the dark, rainy weather starts, it’s easy to assume your lawn can be left alone until spring. But with the right care, you can help your grass stay green, strong, and ready to bounce back as soon as warmer weather returns. After all, winter lawn care is about protection and preparation, not perfection by any means.

In this guide, we’ll cover how to grow grass during winter, how to keep your existing lawn healthy, and the products that can make a big difference through the coldest months.

Can Grass Grow in Winter?

Grass growth naturally slows as temperatures drop below around 8°C. In most of the UK, that means your lawn will go almost dormant between November and February. However, it doesn’t stop completely. Roots continue to develop slowly underground, which means your grass still benefits from nutrients and gentle care where possible.

With milder winters becoming more common, overseeding in late autumn or early winter can still be effective if conditions are mild and the ground isn’t frozen. Using high-quality lawn seed with fast-germinating varieties such as perennial ryegrass can help fill bare patches even in cooler weather.

Preparing Your Lawn Before Winter

The best winter lawn is one that’s been well-prepared in autumn. Taking a few steps before the cold sets in can make a huge difference.

Scarify and aerate to remove moss and thatch and allow air to reach the roots.
Apply autumn or winter fertiliser to strengthen the root system. Choose a low-nitrogen formula from our fertiliser range to avoid excessive leaf growth.
Mow for the last time on a high setting, leaving the grass around 4–5 cm long.
Clear fallen leaves regularly to prevent rot and disease.

Healthy roots are what keep grass strong through cold, wet months. By supporting them before frost hits, you set your lawn up for early spring recovery and a great start to the year.

How to Care for Your Lawn During Winter

Once winter arrives, grass care becomes about protection rather than active growth.

1. Avoid Walking on Frozen or Wet Grass

When frost or snow covers your lawn, walking on it can damage the blades and compact the soil. Try to keep traffic to a minimum, especially on frequently used paths. If compaction does occur, aerate again in early spring if you remember to.

2. Keep It Clear

Remove debris, fallen leaves, and garden furniture where possible. Anything left sitting on the grass can smother it and cause yellow patches. We've all been there.

3. Watch Drainage

Winter rain can lead to waterlogging, especially on clay or compacted soils. If puddles form regularly, improve drainage by lightly spiking the area with a garden fork or aerator. For larger lawns, overseeding in spring with deep-rooting grass from our lawn seed collection can help prevent this long term too.

4. Feed When Needed

Even though growth slows, your lawn still benefits from nutrients. Apply a slow-release winter feed such as those available in our fertiliser collection to keep roots healthy without forcing leaf growth.

5. Manage Moss and Weeds

Cool, damp conditions are perfect for moss and winter weeds. Avoid using harsh weedkillers during cold spells, but you can rake moss out gently and apply a moss control product once temperatures rise slightly. Regular maintenance now saves more intensive repair later.

Overseeding and Growing Grass in Winter

While traditional sowing is best done in spring or autumn, mild winters can still allow limited grass growth if the ground is warm enough. Choose a cold-tolerant grass seed blend containing fescues or perennial ryegrass for the best results.

Tips for winter sowing:

Wait for a mild spell with daytime temperatures above 8–10°C.
Avoid frosty or waterlogged soil.
Keep birds off new seed with fine mesh or fleece.
Use a multi-purpose lawn seed mix designed for fast establishment.
Water lightly only if the weather is dry for several days.

For lawns used by pets or animals, cold-tolerant options from our equine grass seed and paddock seed ranges are also suitable.

Repairing Winter Damage

If your lawn develops thin or muddy patches during winter, don’t worry. These can be repaired easily once temperatures rise.

In early spring, lightly rake to remove dead grass.
Overseed bare areas with lawn and meadow seed.
Topdress with compost or fine soil to help seed-to-soil contact.
Feed and water once growth resumes.

Keeping some spare seed stored indoors means you can repair any damage quickly as soon as conditions improve.

Sustainable Winter Lawn Care

Winter lawn care doesn’t have to rely on chemicals or constant mowing. Natural, eco-friendly solutions such as green manures and wildflower seed mixes can help improve soil structure and biodiversity. Adding wildflower areas around the edges of your lawn supports pollinators and reduces maintenance at the same time.

You can also find practical tools, bird feed, and outdoor supplies to support your garden through the colder months in our home and garden and wild bird collections.

Summary

While grass won’t grow quickly in winter, it can still be maintained and protected with the right approach. Prepare your lawn in autumn, feed it lightly through the colder months, and avoid walking on frozen grass. By early spring, you’ll have a greener, stronger lawn that recovers faster and looks healthier for the year ahead.
