September

September is a lovely in-between month – you can still enjoy late-summer colour, but it’s also the perfect time to start preparing for autumn. With cooler nights and (often) a bit more rain, many garden jobs become easier again – especially lawn repairs, planting, and getting the veg patch ready for the next season.

September jobs in the garden

• Garden protection & weather prep

  Temperatures can dip at night, so keep an eye on tender plants and bring delicate pots into shelter if needed. September is also a great time to tidy and refresh containers, and start thinking about early autumn planting.

• Lawn care

  This is one of the best months for lawns. The soil is still warm, but the weather is cooler – ideal for overseeding, repairing bare patches, and applying an autumn lawn feed. Keep mowing as needed, but you can start raising the cutting height as growth slows.

• Veg patch & seed prep

  Keep harvesting, clear spent crops, and improve soil by adding compost or well-rotted manure. September is also the month to start planning autumn/winter beds and sowing or planting crops for the cooler months (depending on space and weather).

• Trees & shrubs

  Early autumn is a great time to plant, move or divide some garden plants while the ground is still warm. Keep climbers tied in, and tidy summer-flowering shrubs where needed. Collect seeds from favourite flowers if you’d like to grow them again next year.

• Wildlife

  As natural food sources change, keep water available and consider leaving a few seed heads and berries for birds. September is also a good time to add pollinator-friendly autumn plants to support wildlife into the cooler months.

September garden FAQs

Is September a good time to fix the lawn?

Yes – it’s one of the best. Warm soil helps seeds germinate, and cooler weather reduces stress on new grass.

Can I still plant in September?

Definitely. Many shrubs and perennials establish really well in early autumn, giving them a head start before next spring.

Should I start feeding the birds again in September?

If you’ve eased off over summer, September is a good time to start topping feeders up again, especially as the weather cools.

What should I do with my veg patch now?

Keep harvesting, remove spent crops, and improve the soil with compost. It’s a great time to plan what you’ll grow next year too.

When do I start thinking about spring bulbs?

September is when many people begin planning and buying bulbs, even if planting happens a little later – it’s a good time to choose what you want for spring colour.
