As the vibrant colours of summer fade and a crisp chill fills the air, it’s a sure sign that autumn has arrived in Devon. While the cooler days and falling leaves might tempt you indoors, this season is a crucial time for your garden.
Autumn isn’t about winding down; it’s about preparing your outdoor space for the colder months ahead and laying the groundwork for a spectacular spring bloom.
This is the perfect time to tidy, prune, and plant for the future. By tackling these essential autumn gardening jobs now, you protect your garden from common issues like fungal diseases and frost damage, ensuring it remains healthy and resilient.
As Devon-based experts, we at Halcyon Landscapes have helped countless homeowners across Seaton and East Devon get their gardens winter-ready. This guide shares our top tips for autumn gardening, helping you create a space that thrives year-round. In this article, you’ll find practical autumn gardening tips, designed to help you maintain and prepare your garden effectively during the season.
1) Clearing and Tidying Your Garden
One of the most satisfying autumn gardening jobs is a thorough clear-up. Fallen leaves, spent annuals, and other plant debris can smother your lawn and create a damp environment perfect for pests and diseases to thrive. A good tidy-up now will save you a lot of trouble next year.
Key autumn gardening tasks include:
- Rake Fallen Leaves: Regularly clear leaves from your lawn, paths, and borders. A blanket of wet leaves can suffocate grass, encourage moss, and make paths slippery and hazardous. Don’t throw them away; add them to your compost heap to create a nutrient-rich “leaf mould” that your soil will love.
- Clear Out Borders and Beds: Remove spent annuals and any diseased foliage from your perennial plants. This prevents diseases from overwintering in the soil and reinfecting your garden in the spring. After clearing, cover any bare soil with mulch or green manure to prevent weed growth and improve soil health.
- Tidy Up Containers: Empty your summer pots and containers. Clean them thoroughly with hot, soapy water to kill any lingering pests or diseases before storing them for winter.
- Cut Back Perennials: Cut back collapsed stems on perennials to tidy borders and reduce overwintering pests, helping prepare your plants for better growth next season.
2) Pruning and Cutting Back for Spring Growth
Autumn pruning is essential for maintaining the health, shape, and vigour of many plants. Removing dead, damaged, or diseased wood helps to prevent the spread of fungal infections and encourages strong, healthy growth when spring arrives.
In addition, removing dead or unsightly top growth as part of your autumn gardening and grounds maintenance promotes healthy development and prepares plants for winter. However, it’s important to know which plants to prune and how.
What to Prune in Autumn
In Devon, many popular garden plants benefit from an autumn trim. Here are a few examples:
- Roses: Once your roses have finished flowering, it’s a good time to give them a light prune. Remove any dead, diseased, or crossing canes to improve air circulation. This helps prevent black spot and other fungal issues. You can also shorten the main stems by about a third to prevent them from being rocked by strong winter winds, which can loosen the roots.
- Hydrangeas: For many hydrangea varieties, it’s best to leave the faded flower heads on over winter. They provide a beautiful architectural element in the frosty garden and offer some protection to the new buds forming below. Simply cut back any dead or weak stems to the base.
- Lavender: Give English lavender a light trim after it has finished flowering to maintain its compact shape and prevent it from becoming woody and leggy. Be careful not to cut back into the old, bare wood, as it may not regrow from there.
- Perennials: Many herbaceous perennials can be cut back to just above ground level once their foliage starts to die back. This tidies up your borders and removes hiding spots for slugs and snails. However, consider leaving the seed heads on plants like Echinacea and Rudbeckia to provide food for birds and add visual interest to the winter garden.
3) Autumn Lawn Care
Your lawn has likely worked hard over the summer, so giving it some TLC as part of your autumn gardening can go a long way. A little effort now will help it withstand the wet and cold of a Devon winter and ensure it emerges lush and green in the spring.
Late autumn is when grass growth slows, making it an ideal time for final mowing and leaf clearance. Due to climate change, milder winters may mean you need to mow your lawn later into the season than usual.
Proper autumn gardening for the lawn also helps suppress weed growth, leading to a healthier lawn next year.
- Raking: As mentioned, regularly rake leaves off the grass to prevent it from being smothered. A lawn that can’t breathe is more susceptible to moss and fungal diseases like red thread.
- Aeration: If your lawn feels compacted, especially in high-traffic areas, aerating it will do wonders. You can use a garden fork to spike the lawn at regular intervals. This simple action allows air, water, and nutrients to penetrate the soil and reach the grass roots, promoting stronger growth.
- Feeding: Apply an autumn lawn feed. Unlike spring fertilisers, which encourage leafy growth, autumn feeds are rich in potassium and phosphates. These nutrients strengthen the roots and improve the lawn’s resilience to frost and disease, preparing it for the rigours of winter.
- Overseeding: If your lawn has any thin or bare patches, now is an ideal time to overseed. The soil is still warm enough for germination, and there’s plenty of moisture. Before overseeding, remove thatch by scarifying or raking to improve seed-to-soil contact and promote healthy germination. Simply rake the area to loosen the soil, scatter the seeds, and water them in.
4) Planting for a Spectacular Spring
Your autumn gardening routine is also a great time to begin planting for spring. The soil is still warm from the summer sun but moist from autumn rains, creating perfect conditions for roots to establish before winter sets in.
Using well-draining soil is essential when planting bulbs and vegetables to prevent waterlogging and promote healthy growth.
Planting as part of your autumn gardening encourages good root growth, ensuring healthy establishment and vigorous plants in the following year. This gives plants a fantastic head start for the following year.
Bulbs, Hedges, and Shrubs
- Plant Spring Bulbs: For a burst of colour next spring, plant bulbs like daffodils, tulips, crocuses, and alliums now. Some bulbs planted at this time will flower in late spring, extending your display. Plant them at two to three times their own depth in well-drained soil. You can plant them in drifts in your borders for a natural look or pack them into containers for a vibrant patio display. For starting bulbs or seedlings indoors, use small pots to protect delicate young plants before transferring them outside.
- Establish Hedges and Trees: Autumn is the ideal time to plant new hedges, trees, and shrubs. Planting now allows them to develop a strong root system over the winter, meaning they’ll be ready to burst into growth come spring and will be more resilient to any dry spells next summer.
- Consider Coastal Conditions: For those of us with gardens along the beautiful Devon coast, it’s wise to choose planting spots that offer some shelter from salt-laden winds. Planting behind a wall, fence, or an established hedge can make all the difference for more delicate plants.
5) Protecting Your Garden from the Cold
As winter approaches, protecting your garden from frost and wind is a key part of your autumn gardening. Take steps to prevent wind damage to both plants and garden structures, as strong autumn winds can cause significant harm.
- Mulch Your Borders: Practice mulching by applying a generous layer of mulch, such as compost, leaf mould, or well-rotted manure, around the base of your plants. Mulching provides winter protection by insulating roots from frost, conserving moisture, suppressing weeds, and improving soil health.
- Protect Tender and Precious Plants: Move any tender plants in pots, like citrus trees or pelargoniums, into a greenhouse, conservatory, or a sheltered spot by the house. For tender or precious plants in your borders, cover them with horticultural fleece or a cloche on nights when frost is forecast. Safeguarding precious plants from autumn weather extremes, such as heavy rain, strong winds, and frost, is essential to prevent loss or damage.
- Use a Cold Frame: Consider using a cold frame to provide a controlled, unheated environment for starting seedlings or hardening off plants in late autumn or early spring. A cold frame can help protect young or sensitive plants from harsh weather conditions.
- Winterise Ponds and Water Features: Clean out any fallen leaves from ponds to prevent the water from becoming foul. If you have fish, you may need a pond heater or a floating ball to stop the surface from freezing over completely, which ensures oxygen can still reach the water. Drain and store water features or protect them from freezing damage.
- Check Garden Structures: Inspect fences, trellises, and arches for any signs of rot or damage. A winter storm can easily bring down a weakened structure, so make any necessary repairs now.
6) Plan and Prepare for Next Year
Autumn gardening is also a time for reflection and planning. With the garden’s structure laid bare, it’s easier to see what worked well this year and what didn’t. Use this opportunity to walk around your garden with a notebook. Make a note of any problem areas, such as poor drainage, pest hotspots, or patches of poor soil. Think about the planting combinations you loved and those that didn’t quite hit the mark.
This is the perfect moment to dream up new projects for next year. Perhaps you’re considering a new patio for outdoor dining, a redesigned planting scheme focused on achieving colourful blooms for visual appeal and wildlife support, or a complete garden makeover.
Planning now means you can get everything in place to start work in the spring. For larger projects, booking professional help in advance is a smart move.
Autumn gardening, such as composting leaves and reusing gardening supplies, helps recycle nutrients and support next year’s plants. By reusing garden materials and focusing on nutrient retention, you set the stage for healthy growth of the year’s plants in the upcoming season.
Conclusion
Putting in the effort now during these mellow autumn months is one of the most rewarding things you can do for your garden. By following these autumn gardening jobs, you’ll not only keep your space tidy and healthy through winter but also set the stage for a garden that bursts with life and colour next spring.

Frequently Asked Questions
When is the best time to plant spring bulbs in Devon?
The ideal time to plant spring-flowering bulbs in Devon is from September to November. The soil is still warm enough for the bulbs to establish roots before the ground freezes. Planting daffodils and crocuses earlier in autumn is best, while tulips can be planted as late as November, which can help prevent the fungal disease tulip fire.
Should I prune all shrubs in autumn?
No, not all shrubs should be pruned in autumn. While it’s a good time to prune many summer-flowering shrubs like roses and lavender, you should avoid pruning spring-flowering shrubs such as forsythia, lilac, and magnolias.
These plants form their flower buds on old wood during late summer and autumn, so pruning them now would mean cutting off next year’s flowers. It’s best to prune these immediately after they have finished flowering in the spring.
How do I protect coastal gardens from frost and wind?
Coastal gardens in Devon face the unique challenge of salt-laden winds, which can be very damaging to plants. Creating windbreaks using salt-tolerant hedging (like Escallonia or Griselinia) or sturdy fencing is highly effective.
For individual plants, applying a thick layer of mulch around the base insulates the roots from frost. You can also wrap more delicate specimens in horticultural fleece to protect them from both windburn and frost. Choosing hardy, salt-tolerant plants from the outset will give your garden the best chance of thriving.
