Putting Your Garden to Bed for Winter

As the days shorten and temperatures drop, your garden needs care to rest, recover, and thrive next spring. With the right preparation, you can protect your lawn, plants, and outdoor spaces from harsh winter conditions.

Weather-Dependent Timing

Avoid putting your garden to bed too early; you want plants to flourish as long as possible. However, preparation should begin before freezing temperatures or other adverse weather arrive. Grass growth slows below 5°C, signalling that your lawn is entering dormancy and it’s time for essential winter prep.

Month Indicators

Look for signs of seasonal change, such as the shifting colours of trees and leaves. September is a good time to evaluate your garden, with most preparation tasks starting in October and November.

Mow for Autumn and Winter

Give your lawn its final cut of the year. Set your mower to 35–45mm (1.5–2 inches) to protect grass from frost while still allowing photosynthesis.

If a mild spell occurs, you can give it a gentle cut, but only when frost-free and dry.

Aerate Your Lawn

Pierce small holes into the soil using a garden fork or aerator tool to improve air circulation, nutrient absorption, and water drainage. This prevents compaction and strengthens roots for winter.

Get Year-Round Support

If you want to keep things simple and give your lawn the care and nutrients it needs at the right time every season, explore the Your A1 Lawn Subscription Pack. It's delivered every three months with the ideal lawncare products for each season, complete with a handy how-to guide and expert support for any questions you have.

Fertilise for Winter Strength

Apply a nutrient-rich fertiliser to boost root strength and improve resilience.

We would recommend A1 Lawn Ultimate Autumn Winter Fertiliser or Amvista G9 Autumn Winter Fertiliser, formulated with potassium and iron to strengthen and green up your lawn for the colder months.

Apply from September onwards, avoiding frosty days.

Repair Bare Patches

Overseed thinning or bare areas with winter grass seed.

We would recommend A1 Lawn Winter Repair Grass Seed which germinates in temperatures as low as 3°C and is durable for high foot traffic.

Moss Control

Due to the increase in moisture in your lawn, you may find a build-up of moss that you would like to control. Our lawn moss control range works to eliminate moss while keeping your soil and grass strong and green.

Trim Surrounding Plants

Prune nearby shrubs and trees to allow sunlight to reach the lawn during dim winter days. Trim perennials to soil level to protect roots and encourage spring growth.

Clear Dead or Dying Plants

Remove plant debris to prevent pests and disease. Healthy plant matter can be composted; diseased material should be discarded.

Tidy Up Leaves and Garden Debris

Rake fallen leaves, twigs, and debris to prevent fungal growth.

Dampened leaves can be bagged to create leaf mould for compost or mulch.

Sow Wildflowers

Autumn is ideal for sowing wildflower seeds, especially varieties that require frost for germination. These often flower earlier in spring.

Keep Hard Surfaces Clean

Slippery moss and algae can pose hazards during frost. Regular cleaning prevents stains and slip risks.

We would recommend AlgoClear Pro, AlgoClear Home & Garden and softwashing bundles.

Mulch Your Beds

Apply a layer of organic matter (wood chips, bark, ash) to insulate soil, retain moisture, and protect roots.

Control Weeds

Even in winter, weeds can take hold. Apply weed suppressants or a selective lawn weedkiller such as Kurtail Lawn.
