September Gardening Tips: Turning Over a New Leaf

Come September, you’ll notice a real shift in the garden. After one of the driest, warmest summers, this month brings a welcome change. The garden has weathered a lot, but with cooler temperatures and shorter days, we’re finally seeing some respite. Any rain by now should have softened the soil, which, still warm, makes it a good time for planting and establishing new plants, while seedheads, berries and early autumn colour provide new interest.

Use the September cooldown to prepare for autumn and winter. A few jobs will set you up nicely.


Q&S’s Garden Notes – September

7 tasks this month:

  1. Tidy up hedges: Give shaggy hedges a prune now to keep them looking sharp right through to spring.
  2. Plant while soil is warm: It’s a good time to establish new shrubs and perennials this month, while there’s usually more natural moisture around.
  3. Get bulbs in: Plant spring-flowering bulbs like daffodils, crocuses and alliums now for a colourful start to next year.
  4. Don’t stop watering: Newly planted plants and containers still need water in dry spells - preferably with collected rain or grey water - don’t assume cooler weather means plants no longer need water.
  5. Leave some seedheads: They’re a valuable food source and habitat for wildlife through autumn.
  6. Divide overcrowded perennials: It’ll rejuvenate established plants and give you new plants for other areas of the garden.
  7. Resist being too tidy: Stems, seedheads and leaf litter offer valuable shelter and food for insects – a little wildness goes a long way.

Our gardening teams are working in commercial gardens and multi-use settings every day, tending gardens, parks and green spaces across the South East, and we’ve got lots of tips and insights to share.
