Our September gardening tips and jobs take into account the start of meteorological autumn;  the soil is still warm, and perhaps a little more moist, making it a good time to plant some Spring flowering bulbs. Day lengths start to markedly shorten this month, so growth rates slow, and time in the garden becomes a little more limited.

  • Heathers.

Top gardening tips and jobs for September:

Divide herbaceous perennials.
Not only does this multiply your plants, but it also encourages vigorous plants that do well year after year. Plant divided plants as soon as possible and water them in well. You can either replant them in the same position or move them to a new part of the garden. It’s a great opportunity to mix in some compost or other soil improver before replanting.

Pick autumn raspberries.

Collect and sow seed from perennials and hardy annuals.

Dig up remaining potatoes before slug damage spoils them.

Net ponds before leaf fall gets underway.
We sell netting by the metre or pre-packed.

Keep up with watering of new plants, using rain or grey water if possible.

Start to reduce the frequency of houseplant watering and feeding.

Clean out cold frames and greenhouses so that they are ready for use in the autumn.

Cover leafy vegetable crops with bird-proof netting.

Plant spring flowering bulbs.
You’ll find a good choice inside our shop. Narcissi and daffodils make better plants if planted really early because they start to form new roots straight away. Tulips can be bought now but are best planted a little later in November or December – if planted too early they can be affected by fungal diseases.
