As custodians of such amazing gardens it makes sense to share with you some of our top tips on what to do in the garden this September.

While we’re all enjoying the last of the summer sun and warm air, it’s time to start turning our attention to the tasks that will need doing in the garden this September.

At Antony Woodland Garden we are starting to tidy and maintain our plants, shrubs and trees ready for the autumn and winter months ahead. 

Top tips on what to do in the garden this September:

  • What to do in the garden in SpetemberPlant spring-flowering bulbs now, such as daffodils, crocus and hyacinths, for glorious colour in your garden next spring.
  • Deadhead annuals and perennials to extend their performance including hanging-basket and container plants as they will often keep going until the first frosts.
  • Divide your herbaceous perennials. This will keep your plants healthy and vigorous year after year and multiply your stock.
  • Plant out and transplant biennials.
  • Net ponds now before the autumn leaves start to fall to reduce the amount of debris entering the water.
  • Clean out cold frames and greenhouses to get ready for your autumn sowing and growing.
  • Spread newly dug potatoes out to dry for a few hours before storing them in a cool, dark place. Store them in paper or hessian sacks, as this will allow the crop to breathe while it’s in storage.
  • If you are laying turf or a lawn from seed autumn is the best time for lawn establishment.
  • Raise the height of your mower blades as the growth of your grass slows down.
  • Create compost bins (pallets are great for this) in preparation for all the fallen leaves and dead plant material which you’ll be collecting over the coming months.
  • Collect seeds from summer flowering perennials – Hollyhocks, Digitalis and Poppies are great examples of plants that produce fantastic seed heads that can be collected and sown for flowers the next year.
  • Move any house plants back indoors to avoid the dropping temperatures.
  • Plant autumn onion sets, shallots and garlic for an early crop next year.
