October Garden Jobs UK
Matt W | Greenhouse Installer & Gardener
October is the busiest month in the UK gardening calendar. Plant spring bulbs before month end. Harvest apples, pears and root vegetables. Prepare your greenhouse for winter growing. Expect first frosts from mid-October in most regions. This guide covers 25+ jobs across flowers, vegetables, fruit, lawn and greenhouse, with timings based on real UK growing conditions.
Key Takeaways
- Plant tulips, daffodils and crocuses before the end of October.
- Harvest and store apples, pears and root vegetables now.
- Clean greenhouse glass inside and out to maximise winter light.
- Move tender plants indoors before temperatures drop below 10 degrees.
- Plant garlic cloves 15 cm apart for next year's harvest.
Installer's Note
We fit greenhouses year-round, and October is when we see the most damage from neglected prep. Loose panes, cracked seals and blocked gutters all get worse once winter storms arrive. Spend an afternoon checking your greenhouse structure now and you avoid emergency repairs in January. We replaced three shattered panes last December that would have survived if the owner had re-sealed them in October.
October is a beautiful month of autumnal colours and first frosts. Crisp, blue-sky days are perfect for tidying up and cutting back in the garden. The jobs you complete now decide how well your garden survives winter. They also determine how strongly it comes back in spring.
Flowers and borders
October is your final opportunity for spring bulb planting and essential border preparation. These tasks set up next year's displays.
Bulbs, bedding and border prep
- Plant spring bulbs - tulips, daffodils, crocuses and fritillaries in well-draining soil.
- Plant winter bedding - wallflowers, pansies and winter-flowering heathers.
- Lift tender bulbs - dahlia tubers, begonia tubers and gladioli corms for winter storage.
- Divide perennials - astilbe, day lilies and hardy geraniums whilst soil is warm.
- Take hardwood cuttings - roses, forsythia and weigela from deciduous shrubs.
- Mulch borders - 5-7 cm layer of compost around plants for winter protection.
- Protect tender plants - wrap tree ferns and cordylines with fleece. Read our overwintering plants guide for full details.
Bulb planting tip: Plant bulbs three times their own depth. Add grit to heavy soils for drainage.
Dividing perennials: I divide perennials every 3-4 years using two forks back-to-back. Each division needs strong roots and growing shoots for best results.
In the vegetable garden
October harvesting and winter preparation are the main tasks in the veg patch. Here is what needs doing now.
Harvesting and storage
- Harvest main crops - potatoes, carrots and beetroot before soil waterlogging.
- Lift and store - onions, garlic and pumpkins before first frost.
- Finish picking beans - save some pods for next year's seed.
- Clear finished crops - remove old plant debris to prevent disease.
Planting and sowing
- Plant garlic cloves - 15 cm apart, tips 5 cm below surface in a sunny spot.
- Sow broad beans - hardy varieties for an early crop next year.
- Plant spring cabbages - in a prepared bed with firm soil.
- Sow green manure - winter rye on empty beds prevents nutrient loss.
Storage tip: Only store perfect vegetables. Use damaged ones immediately or preserve them.
Green manure benefits: Fixes nitrogen, prevents erosion and improves soil structure when dug in during spring.
In the fruit garden
October is peak harvest time for tree fruits and an essential maintenance period for soft fruits.
Tree fruits
- Harvest apples and pears - test ripeness by gentle lifting.
- Wrap grease bands - around trunks to trap winter moth females.
- Remove diseased fruit - from trees and ground to prevent reinfection.
- Apply winter wash - to kill overwintering pests on bark.
Apple storage: Only store unblemished fruit in cool, dark conditions. Check regularly and use damaged ones first.
Ripeness test: I test apple ripeness by cupping fruit in my palm. Ripe apples lift away easily without tugging.
Soft fruits
- Prune summer raspberries - cut old canes to ground and tie in new ones.
- Cut autumn raspberry canes - to ground level after final harvest.
- Clean strawberry beds - remove old straw and dead foliage.
- Divide rhubarb - lift and split congested crowns.
House plants
As daylight reduces and temperatures drop, house plants need adjusted care. Some outdoor plants need moving indoors.
Moving plants indoors
- Bring tender plants inside - before temperatures consistently drop below 10 degrees C.
- Check for pests - inspect thoroughly before bringing indoors.
- Quarantine new arrivals - keep separate for two weeks.
- Clean large leaves - wipe dust from plants that were outside.
Indoor care adjustments
- Reduce watering frequency - plants need less as growth slows.
- Move to brighter spots - maximise available light.
- Stop feeding - most plants enter a dormant period.
- Take cuttings - propagate from healthy growth before dormancy.
Light tip: Clean windows and rotate plants weekly for even light exposure.
Watering check: Test soil moisture with the finger test. Water only when the top inch feels dry.
In the greenhouse
October greenhouse preparation maximises winter growing potential and ensures proper plant protection. Winter greenhouse growing extends your season by months.
Cleaning and maintenance
- Wash glass thoroughly - inside and out to maximise light transmission.
- Disinfect surfaces - benches, pots and tools to kill disease spores. Our guide to controlling grey mould in the greenhouse explains why this matters.
- Check glazing - replace broken panes and seal gaps.
- Service heating - test systems before cold weather arrives.
Winter preparation
- Install insulation - bubble wrap on north walls reduces heat loss by 40%. See our greenhouse insulation guide for step-by-step instructions.
- Set up heating - greenhouse heaters sized for your space.
- Sow winter crops - lettuce, spinach and rocket for fresh winter salads.
- Plant amaryllis bulbs - for Christmas flowers.
Insulation tip: Leave ventilation gaps. Completely sealing your greenhouse creates condensation problems.
Heating efficiency: Wooden greenhouses provide better insulation than aluminium structures.
Matt's Tip: October Greenhouse Priorities
Do not skip the glass clean. Dirty glass cuts light levels by 30-40% and your winter crops will suffer. I use a long-handled brush with warm soapy water on the outside, then a squeegee on the inside. It takes about an hour for a 6x8 greenhouse. That single hour gives your winter salads the light they need. Otherwise they just sit there looking pale.

Looking after your lawn
October lawn care focuses on winter preparation and taking advantage of mild conditions for final maintenance.
Essential lawn tasks
- Final mowing - when growth stops, usually mid-October.
- Raise cutting height - to 2.5-3 cm to avoid scalping.
- Clear fallen leaves - weekly raking prevents fungal diseases.
- Aerate compacted areas - use a garden fork to improve drainage.
- Overseed thin patches - grass seed establishes well in October.
- Apply autumn feed - low-nitrogen fertiliser for winter strength.
New lawn projects
- Lay turf - autumn conditions are ideal for establishment.
- Plant bulbs in grass - crocuses and daffodils for spring display.
- Install lawn edging - makes future maintenance easier.
- Repair damaged edges - cut out and re-turf worn areas.
Leaf management: Compost leaves separately or use as mulch. Do not mix with grass clippings.
Mowing tip: Continue weekly cuts until growth stops completely after several days below 5 degrees C.
Other garden jobs
October's general maintenance tasks prepare your garden infrastructure for winter weather and create safe, tidy outdoor spaces.
Infrastructure and safety
- Clean paths and patios - remove slippery algae and leaves.
- Drain water systems - hoses, pipes and irrigation to prevent freezing.
- Check garden structures - fences, trellises and supports before storms. Our greenhouse wind damage guide covers what to look for.
- Test garden lighting - ensure safe access during dark months.
Tool and equipment care
- Clean and oil tools - prevent rust during winter storage.
- Service mowers - clean, sharpen and store properly.
- Organise sheds - protect valuable equipment from damp.
- Check shed security - repair locks and weatherproof roofing.
Wildlife and environment
- Set up bird feeding stations - winter food sources become scarce.
- Create wildlife habitats - leave some leaf piles for beneficial insects.
- Install bird baths - provide unfrozen water sources.
- Build compost systems - process autumn debris into soil improver.
Pest management: October slug and snail hunts reduce next year's population significantly.
Winter preparation
- Well-maintained equipment lasts decades longer than neglected tools.
- Schedule storm checks after high winds to catch damage early.
- Top up grit supplies for icy paths and drives.
October preparation makes the difference between a spring bounce-back and weeks of recovery work. Finish the frost-sensitive jobs first, then work through the rest at your own pace. Already thinking ahead? Our December gardening jobs UK guide picks up where November leaves off.
Frequently asked questions
What garden jobs should I prioritise in October?
Plant spring bulbs and harvest tender crops before first frost. Tulips, daffodils and crocuses need to go in before month end. Clear fallen leaves from lawns weekly to prevent fungal disease. Move tender plants to frost-free locations. These tasks have strict deadlines before winter weather arrives.
What allotment jobs are essential in October?
Harvest remaining crops, clear spent plants and sow green manure. Lift potatoes, carrots and apples. Plant garlic and broad beans for next year. Cover empty beds with winter rye to prevent nutrient loss. Clean and organise tool storage areas before the wet weather sets in.
What vegetables can I sow in October in the UK?
Sow broad beans, winter lettuce, rocket and lamb's lettuce outdoors. Overwintering peas, winter purslane and corn salad also establish well this month. Plant garlic cloves, onion sets and spring cabbage plants. Green manure crops like winter rye work well on empty beds.
What needs pruning in October UK?
Prune summer-fruiting raspberry canes and reduce shrub rose height. Cut old raspberry canes to ground level and tie in new growth. Reduce roses by a third to prevent wind rock damage. Cut back finished herbaceous perennials. Avoid pruning spring-flowering shrubs as you will remove next year's buds.
When should I start protecting plants from frost?
Begin frost protection in early October before the first frost arrives. Move tender plants to sheltered spots and have fleece ready. UK October frosts can arrive unexpectedly, especially inland. Preparation always beats reaction when it comes to frost damage.
Should I continue mowing my lawn in October?
Yes, continue mowing while grass is still growing. Growth typically stops by mid-October in most UK regions. Raise the cutting height to 2.5-3 cm and reduce frequency as growth slows. Stop completely when grass stops growing after several consecutive days below 5 degrees C.
What is the latest I can plant spring bulbs?
Plant most spring bulbs by the end of October for best results. Tulips can go in until early November, but earlier planting gives better root establishment. Daffodils and crocuses should ideally be in the ground by mid-October. Plant at three times the bulb's own depth.
How do I prepare my greenhouse for winter?
Clean all glass inside and out, then check glazing for damage. Install bubble wrap insulation on north-facing walls. Test heating systems before cold weather arrives. Move tender plants inside gradually over a week to reduce transplant shock. Ensure good ventilation whilst maintaining warmth.
Can I still harvest vegetables in October?
October is peak harvest time for most UK fruit and vegetable gardens. Apples, pears, late potatoes, carrots, beetroot, pumpkins and winter squashes are all ready now. Many root vegetables can stay in the ground until needed, but harvest before soil becomes waterlogged.
What pest control should I do in October?
Focus on slug and snail control with regular evening hunts. Removing them now reduces next year's population significantly. Clear plant debris that harbours pests. Apply grease bands to fruit trees to trap winter moth females. Check plants for overwintering pest eggs and destroy them.
