September is the bridge between summer and autumn. The days may still feel warm, but cooler nights and shorter daylight hours signal big changes in the garden. Now’s the time to tidy, plant, and prepare for the colder months ahead while enjoying the last bursts of summer colour.
Here’s your essential September garden checklist:
1. Lawn Care
- Scarify to remove moss and thatch.
- Aerate compacted areas with a garden fork or aerator.
- Overseed bare patches for a thicker lawn next year.
- Apply an autumn lawn feed (low nitrogen, higher potassium).
2. Plant for the Future
- Plant spring-flowering bulbs like daffodils, crocus, and alliums.
- Sow hardy annuals such as sweet peas for early blooms next year.
- Pot up containers with pansies, violas, and cyclamen for winter colour.
3. Vegetable Plot
- Harvest beans, courgettes, and tomatoes.
- Plant garlic and overwintering onions.
- Sow spinach, winter lettuce, and oriental greens.
4. Pruning & Tidying
- Deadhead dahlias and roses to prolong flowering.
- Cut back perennials that are past their best.
- Trim hedges — but check for nesting birds first.
5. Support Wildlife
- Leave seed heads for birds.
- Top up bird feeders and water bowls.
- Create a log pile or compost heap for hibernating creatures.
🌿 Final Thought: A little time spent now keeps your garden colourful this autumn and thriving into spring.
