The jobs you do now — from tidying and planting to protecting and preparing — will not only keep your garden looking good through winter but also ensure a strong start in spring.

This autumn gardening checklist covers everything you need to do before winter arrives, helping you care for your vegetables, flowers, lawn, and wildlife while keeping your garden in top condition.

Autumn Gardening Checklist

1. Harvest the Last of Your Crops

• Lift maincrop potatoes before frost damages them.
• Harvest pumpkins, squashes, and late courgettes.
• Pick apples, pears, and plums.
• Gather carrots, parsnips, and beetroot for winter storage.

✅ Store potatoes in sacks, squashes in a cool place, and surplus fruit in a dark, ventilated shed.

---

2. Plant Garlic and Onions

• Plant garlic cloves in October–November for a summer harvest.
• Plant autumn onion sets (e.g., Radar, Shakespeare, Electric).
• Ensure free-draining soil and add compost before planting.

✅ Autumn planting gives earlier, stronger crops the following year.

---

3. Sow Autumn Crops

• Broad beans and peas for early spring harvests.
• Winter salads like lamb’s lettuce, rocket, and mizuna.
• Spinach and chard for hardy, leafy greens.

✅ Cover with fleece or cloches to protect young seedlings.

---

4. Plant Spring Bulbs

• Daffodils, crocuses, and hyacinths by October.
• Tulips in November to prevent disease.
• Layer bulbs in pots for long-lasting displays.

✅ Plant at three times the bulb’s depth for best results.

---

5. Tidy and Prune Flower Beds

• Cut back faded perennials (leave some seed heads for wildlife).
• Prune roses lightly to prevent wind rock.
• Divide and replant overcrowded perennials like hostas and daylilies.

✅ Clearing beds now reduces pests and diseases next spring.

---

6. Improve Soil Health

• Dig in well-rotted manure or compost to boost nutrients.
• Sow green manures (clover, field beans) to cover bare soil.
• Mulch borders with bark or compost to retain moisture and insulate roots.

✅ Healthy soil now = stronger plants next year.

---

7. Look After Your Lawn

• Rake up fallen leaves to prevent smothering grass.
• Aerate compacted areas with a garden fork.
• Reseed bare patches with autumn grass seed.
• Apply autumn lawn feed (high potassium, low nitrogen).

✅ Prepares grass for winter and stronger growth in spring.

---

8. Care for Trees, Shrubs, and Hedges

• Plant new trees and shrubs while soil is warm and moist.
• Wrap young or tender plants in fleece for frost protection.
• Prune hedges lightly before winter winds.

✅ Autumn planting helps roots establish before spring.

---

9. Protect Tender Plants

• Bring pots of geraniums, citrus, and tender herbs indoors.
• Use fleece, cloches, or cold frames for borderline-hardy crops.
• Mulch around the base of borderline-hardy perennials.

✅ Prevents frost damage and overwinter losses.

---

10. Prepare Greenhouses and Sheds

• Clear out old plants and compost.
• Wash greenhouse glass to maximise light.
• Insulate with bubble wrap for winter.
• Clean and oil garden tools.
• Store hoses and watering cans to prevent frost damage.

✅ A tidy shed and clean greenhouse save time in spring.

---

11. Build and Repair Garden Structures

• Fix broken fences, trellises, or raised beds before winter storms.
• Start new garden projects such as compost bins or cold frames.

✅ Autumn is a practical time for DIY jobs with cooler weather.

---

12. Support Garden Wildlife

• Add bird feeders with sunflower seeds, peanuts, and fat balls.
• Provide water in birdbaths, breaking ice in frosts.
• Leave piles of logs and leaves for hedgehogs and insects.
• Avoid cutting everything back — some seed heads feed birds.

✅ A wildlife-friendly garden reduces pests and encourages pollinators.
