Autumn Tasks at the Allotment: Preparing for the Cosy Season

As summer gracefully fades away and the days grow shorter, it's time for gardeners to embrace the enchantment of autumn. At the allotment, this season brings a unique blend of tasks and rewards. The vibrant hues of changing leaves, the crispness in the air, and the promise of hearty harvests make it a magical time. In this guide, we'll delve into the essential autumn tasks that will ensure your allotment thrives and provides abundant produce for the coming months.

1. Harvesting the Last of Summer's Allotment Bounty


Before diving into autumn-specific tasks, make sure to gather the last remnants of your summer crops. Tomatoes, cucumbers, zucchinis, and peppers are often still producing in early autumn. Don't let any go to waste; they're perfect for fresh meals, canning, or freezing.

2. Clearing Out Spent Crops

Once you've harvested the last of your summer crops, it's time to clear out any spent plants. Remove diseased or pest-ridden foliage to prevent the spread of problems into the next growing season. Compost healthy plant material to enrich your soil.

3. Soil Maintenance and Improvement

Healthy soil is the foundation of a thriving allotment. Autumn is an ideal time to amend your soil:

  • Composting: Collect fallen leaves, kitchen scraps, and garden waste to create nutrient-rich compost. The decomposition process will continue over the winter, providing you with black gold for spring.

  • Cover Crops: Sow cover crops like clover, winter rye, or hairy vetch to protect the soil from erosion, suppress weeds, and improve its structure. These green manures also fix nitrogen, enriching the soil.

  • Mulching: Apply a layer of organic mulch, such as straw or well-rotted compost, to protect the soil from erosion and temperature fluctuations. Mulch will break down over time, further enriching the soil.


4. Tending to Perennials and Herbs

Perennial crops like asparagus, rhubarb, and certain herbs require attention in autumn:

  • Pruning: Trim back perennial herbs like mint and oregano to prevent them from taking over the plot. Cut asparagus ferns down to ground level after they've turned brown.

  • Dividing: If your perennials have become overcrowded, consider dividing them. This promotes healthier growth and can yield new plants to share or trade with fellow allotment holders.

5. Planting for Autumn and Beyond

Don't think that planting season is over with the arrival of autumn. Many vegetables thrive in cooler weather and can provide fresh produce well into the winter months:

  • Garlic: Plant garlic cloves in the autumn for a bountiful summer harvest. Ensure well-drained soil and mulch to protect from frost.

  • Onions and Shallots: Like garlic, onions and shallots can be planted in autumn for a summer harvest. Space them well and keep the area weed-free.

  • Overwintering Vegetables: Consider planting hardy vegetables like kale, spinach, and winter lettuce that can endure colder temperatures. Use row covers or cloches to protect them from harsh frosts.

6. Tackling Weeds

Autumn is an excellent time to wage war on persistent weeds:

  • Weed Removal: Remove any weeds that have sprung up during the growing season. Eliminate them before they have a chance to drop seeds and multiply.

  • Mulch: As mentioned earlier, mulch serves as a barrier against weeds by smothering them and preventing them from germinating.

7. Pest and Disease Prevention

Autumn is a crucial time to prevent pests and diseases from overwintering in your allotment:

  • Cleaning Tools: Sterilize your gardening tools to prevent the spread of disease. Clean and sharpen pruners, hoes, and shears.

  • Remove Diseased Plants: Any plants that showed signs of disease during the growing season should be removed and disposed of properly, not composted.

8. Composting Leaves and Garden Debris

Autumn provides an abundance of fallen leaves and garden debris, which can be turned into valuable compost:

  • Leaf Mould: Collect fallen leaves and create leaf mould by allowing them to decompose over time. Leaf mould is an excellent soil conditioner.

9. Organising and Planning

As you wrap up the growing season, take some time to organise your allotment:

  • Record-Keeping: Reflect on the season, noting what worked and what didn't. Keep a gardening journal to plan for the following year.

  • Tool Maintenance: Clean and store your gardening tools properly. This prevents rust and extends their lifespan.

  • Crop Rotation: Consider crop rotation to prevent soil depletion and reduce the risk of pests and diseases.

10. Enjoy the Fruits of Your Labour

Autumn is also a time for celebration. Harvest festivals, gatherings with fellow gardeners, and tasting the first bites of your autumn-grown produce can be immensely rewarding. Take a moment to savor the beauty and tranquillity of your allotment as it transitions into its winter slumber. In conclusion, autumn at the allotment is a time of transition and preparation. By completing these essential tasks, you'll set the stage for a successful growing season next year while enjoying the serene beauty and delicious harvests that autumn has to offer. Embrace the rhythm of the seasons, and your allotment will continue to flourish year after year. Happy gardening! 🌱🍁
