Autumn Allotment Guide: From Harvest to Winter Prep

Introduction

Autumn is one of the most rewarding and busiest times of year on the allotment. As summer crops finish and the days grow shorter, your plot enters a new phase of activity. Harvesting, clearing, planting, and protecting are all vital to keep your allotment productive and healthy through the colder months.

This autumn allotment guide takes you step by step from harvest to winter prep, ensuring you make the most of the season while setting yourself up for success in spring.

Why Autumn Matters on the Allotment

• Maximises your harvest of late crops like pumpkins, parsnips, and apples.
• Prepares soil for winter and restores nutrients for next year.
• Extends the growing season with overwintering crops.
• Protects plants from frost, pests, and harsh weather.
• Saves time in spring by completing groundwork early.

Step 1: Harvest the Last of Your Crops

Autumn is a season of abundance, but it’s important to harvest before frost damages your crops.

• Potatoes: Lift maincrop potatoes before frost blackens the foliage. Store in hessian sacks in a dark shed.
• Pumpkins & Squashes: Harvest when skins are hard and stems woody. Cure in the sun or indoors for storage.
• Root Vegetables: Carrots, beetroot, and parsnips can stay in the ground but benefit from mulch or fleece.
• Fruit: Pick apples, pears, and plums before they fall and bruise. Store in trays in a cool place.

✅ Surplus harvests can be preserved through freezing, pickling, or chutney-making.

Step 2: Clear Away Spent Crops

Old plants can harbour pests and diseases if left over winter.

• Remove blighted potato and tomato plants (do not compost).
• Chop healthy spent crops into small pieces for the compost heap.
• Pull up old bean and pea plants but leave roots in the soil — they add nitrogen.
• Weed thoroughly to reduce spring problems.

✅ A clean plot now means healthier crops next year.

Step 3: Improve Soil Health

Autumn is the best time to give back to your soil.

• Spread well-rotted manure or compost over empty beds.
• Sow green manures such as rye, clover, or field beans to add nutrients and protect structure.
• Mulch with straw, bark, or leaf mould to insulate soil and suppress weeds.

✅ Healthy soil in autumn = strong crops in spring.

Step 4: Plant Autumn and Winter Crops

Keep your allotment productive by planting hardy vegetables.

• Garlic: Plant cloves 15cm apart in October–November.
• Onions & Shallots: Plant autumn onion sets for an early summer harvest.
• Broad Beans: Sow Aquadulce Claudia in October–November for a head start.
• Peas: Try hardy varieties like Meteor.
• Winter Salads: Sow spinach, lamb’s lettuce, or rocket under cloches.

✅ These crops overwinter and give you an early harvest next year.

Step 5: Protect Tender Plants

Not all plants will survive the UK winter without help.

• Lift and store dahlia tubers and gladioli in frost-free conditions.
• Move pots of tender herbs like basil indoors.
• Use fleece, cloches, or polytunnels to extend the season for salads and beans.

---

Step 6: Prepare Fruit Areas

Fruit trees and bushes need attention in autumn.

• Plant new bare-root fruit trees (apple, pear, plum, cherry) and bushes (currants, raspberries, gooseberries).
• Prune summer raspberries by cutting old canes to the ground.
• Remove weeds around fruit beds and mulch heavily with compost.
• Protect young trees with tree guards against frost and rabbits.

Step 7: Maintain Perennial Beds

Perennial crops return year after year with the right care.

• Cut back rhubarb leaves after the first frost.
• Mulch crowns of rhubarb and asparagus.
• Weed thoroughly to reduce spring competition.

---

Step 8: Tidy Paths, Sheds, and Structures

Autumn is the time to repair and prepare allotment infrastructure.

• Fix broken fences, raised beds, and trellises.
• Lay woodchip or gravel paths to keep mud down.
• Clear sheds, sharpen tools, and store hoses.
• Wash greenhouse glass to maximise winter light.

---

Step 9: Care for Compost and Leaves

Autumn produces plenty of organic matter.

• Add vegetable peelings, old crops, and grass cuttings to compost.
• Balance “greens” (nitrogen-rich) with “browns” (cardboard, straw, leaves).
• Collect fallen leaves separately in sacks to make leaf mould.
• Turn compost heaps to speed decomposition.

---

Step 10: Support Wildlife on Your Allotment

Encouraging wildlife makes your allotment healthier and more balanced.

• Provide food for birds with feeders and fat balls.
• Add water sources like shallow dishes or birdbaths.
• Leave log piles for hedgehogs and insects.
• Avoid clearing everything — leave some wild areas.

---

Step 11: Plan for Next Year

Autumn is a season of reflection and preparation.

• Review this year’s successes and challenges.
• Rotate crops to prevent soil-borne diseases.
• Order seeds early for the best choice.
• Sketch layouts and plan allotment improvements.
