What to Do in the Garden Each Autumn Month

Introduction

Autumn in the UK brings shorter days, cooler nights, and the start of the gardening year’s winding down. But while the summer flowers fade and vegetable beds empty, there’s still plenty to do. Each autumn month — September, October, and November — has its own unique jobs that will keep your garden productive, tidy, and prepared for winter.

This guide breaks down what to do in the garden each autumn month, helping you stay organised, protect your plants, and prepare for spring success.

September: Harvest, Plant, and Prepare

September is the start of autumn, but the garden is still vibrant. It’s a month of harvesting, planting new crops, and tidying up beds.

Vegetable Garden

• Harvest maincrop potatoes before frost damages them.
• Pick pumpkins, squashes, and late courgettes.
• Gather carrots, beetroot, and parsnips.
• Plant autumn onion sets and garlic cloves.
• Sow broad beans and peas for an early spring crop.
• Sow quick crops like rocket, spinach, and lamb’s lettuce.

Flower Garden

• Plant spring-flowering bulbs: daffodils, crocuses, hyacinths.
• Divide overcrowded perennials such as daylilies and hostas.
• Deadhead dahlias and roses to extend their blooms.

Lawn Care

• Rake early fallen leaves.
• Aerate compacted lawns.
• Apply autumn lawn feed (low nitrogen, high potassium).

Wildlife

• Leave some seed heads for birds.
• Keep birdbaths filled with clean water.

October: Planting and Protecting

By October, temperatures cool and days shorten, making it the perfect time to plant hardy crops and prepare your garden for winter.

Vegetable Garden

• Continue planting garlic and onion sets.
• Sow hardy broad beans and peas under cloches.
• Clear spent summer crops and compost healthy waste.
• Cover bare beds with mulch or green manure.

Flower Garden

• Plant tulip bulbs (ideally later in November).
• Lift and store tender dahlias, gladioli, and cannas.
• Cut back faded perennials, but leave some seed heads for wildlife.
• Plant bare-root shrubs, roses, and trees.

Lawn Care

• Keep raking fallen leaves to prevent smothering grass.
• Scarify lawns to remove moss and thatch.

Wildlife

• Clean and top up bird feeders.
• Build a hedgehog house or create a log pile.

November: Finishing Touches and Protection

November marks the transition into winter. Frosts arrive, most planting is complete, and it’s time to protect and maintain your garden.

Vegetable Garden

• Finish planting garlic and onions in milder regions.
• Mulch carrots and parsnips to keep them in the ground longer.
• Empty compost bins and spread well-rotted compost on beds.
• Cover soil with fleece, mulch, or cardboard to suppress weeds.

Flower Garden

• Plant tulips now to prevent fungal disease (tulip fire).
• Mulch roses and tender perennials.
• Prune climbing roses and tie in loose stems.
• Move pots to sheltered spots or insulate them with bubble wrap.

Lawn Care

• Rake final leaf fall and store leaves in bags for leaf mould.
• Avoid walking on frosty or waterlogged lawns.

Wildlife

• Provide extra bird food as natural supplies dwindle.
• Break ice on birdbaths in frosty weather.
• Leave leaf piles for hedgehogs, frogs, and insects.

Extra Autumn Jobs for All Months

• Clean greenhouses and insulate with bubble wrap.
• Wash pots, trays, and tools with disinfectant.
• Repair sheds, fences, and raised beds before winter storms.
• Plan your crop rotation and order seeds for spring.

Each autumn month brings its own set of gardening tasks, from September’s harvesting and planting, to October’s preparation and protection, and finally November’s finishing touches before winter.
