The Gardener’s Calendar in September

“Departing summer hath assumed
An aspect tenderly illumed,
The gentlest look of spring;
That calls from yonder leafy shade
Unfaded, yet prepared to fade,
A timely carolling.”
–  William Wordsworth, September

Easing now towards Autumn the heat gives way to a gentle warmth on the back of gardeners enjoying the last summer flush. Temperatures are lower, nights are much cooler and you’ll start to see plants beginning to fade. With the soil recovering it’s moisture levels now is an excellent time to start planning, and planting, for next spring. Daffodils, Narcissus or perhaps for something a little earlier how about some Autumn flowering Crocus. It’s a busy time for farmers and it’s a busy time for gardeners and we have lots to help you get the best out of you garden all year round at Bumbles Plant Centre

Things to do in September:

  1. Sow new lawns, aerate lawns, feed and weed and re-sow bare patches of grass.
  2. During late hot spells keep moisture levels up around late flowering perennials such as Dahlias.
  3. Plant evergreen hedging towards the end of the month.
  4. Plant out young plants into the border, they’ll have time to settle before the winter.
  5. Bring tender pot plants in if you gave them a summer outside
  6. Plant out primulas raised from seed
  7. Dead-head, tie in shoots on climbers, trimming as necessary to keep them looking tidy.
  8. Divide and transplant rock plants that have spread too much.
  9. Plant out your spring bulbs in situ now and they’ll settle in well for a Spring show.
