Sarah's Top Tips for September

Sarah’s Top Tips for your September Garden

We have a very exciting month ahead of us here at Singleton’s as we plan our re-opening of the Potting Shed! We are really looking forward to seeing you all again after such a strange summer! All of our Winter Hanging Basket plants are getting big so get ready to place your orders through our website when it goes live at the end of the month.

September is the month for tidying up and preparing the soil for next year’s crops and flower beds before the autumn settles in.

Let’s get the hard jobs out of the way first!

  • Mulch bare areas with a low nutrient mulch such as leaf mould or semi-rotted straw.
  • Green manures are an excellent way of re-introducing nitrogen into the soil. Winter varieties such as Vetch or Rye are frost hardy and long-lasting and can be easily dug over next spring but should be sown before the first frosts to give them a head start.
  • Remove compost that has collected at the bottom of your compost bins and bag it up for next spring. Empty your bin as much as possible to make room for autumn leaves.

Lawn and hedge care

  • Rake out thatch from your lawn and methodically aerate the lawn by sticking a garden fork into the surface and wiggling it about a bit. This is quite a time-consuming process so you may want to do a little bit at a time or you can only focus on the areas that are more compacted.
  • Brush a well-draining lawn dressing into the aeration holes using a stiff broom. If possible, choose a product that is low on nitrogen as this would promote leafy new growth when the turf should be focussing on root development. A high potassium feed is best for disease prevention.
  • Lift up the blades on your lawn mower and mow less often.
  • When trimming your hedges, leave some of the clippings tucked underneath for small creatures such as frogs and hedgehogs to hibernate in.


  • Use your garden rake to remove any free-floating pond weed and dead foliage before insects and amphibians start to hibernate. Make a small pile to the end of the pond for little creatures to crawl back into the water.
  • This is also a great time to build a new pond! Soils will be softened from recent rains but not too wet. Most aquatic plants respond better to being planted in the spring when the freezing temperatures are behind them.

Garden and Allotment

  • Trim off and plant up stray strawberry runners for next year. Cutting runners off the mother plant allows it to focus on conserving energy for the winter.
  • Keep dead-heading your Dahlias, rose and perennials to extend the season! Cut back other perennials as they begin to fade and compost the dead materials.
  • Plant spring bulbs such as daffodils, crocuses, bluebells soon but leave Tulips until November as the colder weather reduces the risk of disease setting in.

Our winter bulbs are trickling in and we have a new bulb gift range in store which are perfect for giving to friends and family after a long lockdown 🤗
