September is a pivotal month for gardening in the UK as it marks the transition from summer to autumn. There’s a variety of tasks you can engage in to ensure your garden thrives in this transitional period and sets the stage for the seasons to come. Here’s a comprehensive guide to what you should be doing in your garden during September:
Lawn Care:
- Aeration: September is an excellent time to aerate your lawn. Use a garden fork or specialized aerating tools to alleviate compaction and enhance soil drainage.
- Overseeding: Fill in bare patches by overseeding your lawn. The cooler temperatures and potential rainfall will aid germination.
Planting and Transplanting:
- Bulbs: Plant spring-flowering bulbs such as daffodils, tulips, and crocuses for a burst of colour next year.
- Perennials: Early September is suitable for planting new perennials, giving them time to establish their root systems before winter.
- More:
- Turnip, spinach, winter lettuce, and Asian vegetables.
- Overwintering onion sets
- Spring cabbages
Harvesting Fruits and Vegetables:
Many crops are ready for harvesting in September. This includes apples, pears, plums, raspberries, and late-season vegetables like carrots, beets, and winter squashes.

Pruning:
- Summer-Flowering Shrubs: After their flowering period, prune shrubs like lavender and cistus to maintain shape and promote growth.
- Roses: Deadhead spent blooms and lightly prune roses to encourage further flowering before winter.
Dividing and Propagating:
- Perennials: Divide overcrowded perennials like hostas and irises. This rejuvenates the plants and provides an opportunity to expand your garden.
- Cuttings: Take semi-hardwood cuttings of favorite shrubs for propagation.
Preparation for Winter:
- Mulching: Apply a layer of mulch around the base of plants to protect their roots from freezing temperatures and reduce weed growth.
- Tender Plants: If you have tender plants that won’t survive the winter outdoors, start preparing them for indoor conditions by gradually acclimating them to lower light and humidity.
Composting:
- Fall Cleanup: As you tidy your garden for winter, add plant debris, leaves, and other organic matter to your compost pile.
- Compost Application: Spread mature compost on flower beds and borders to enrich the soil for the next growing season.
