September is one of those pivotal months, the change in the seasons means saying goodbye to summer and getting ready to welcome autumn.
I like a lingering goodbye to summer, leaving herbaceous plants and annuals for as long as possible until they’re just past their best, then adding them to the compost bin to rot down and be used in the garden next year. As long as hedges are trimmed and the lawn cut and edged, the garden can be left in a naturalistic state without looking abandoned.
Meanwhile preparation for later in the year carries on:
- Start planting spring flowering bulbs this month [daffodils, hyacinths, crocus etc] this month, but leave tulip planting until November.
- Sow annuals seeds now to flower next year, you’ll get bigger plants earlier.
- Plants stop making flowers when they produce seeds, so keep dead-heading them and they’ll continue flowering for a bit longer.
- Trim conifer hedges in early September so that any new growth has time to toughen up before the first frosts arrive.
The soil is warm and welcoming in late September to early autumn, so it’s the ideal time for planting shrubs and trees if you need more colour and shape or have glaring gaps in your garden.
Happy gardening, Jill
