September – what to do in your garden
Generally a cooler, gustier month than August and the days are noticeably shorter. While there’s not as much to do in the ornamental garden at this time of the year, if you have a fruit or vegetable patch, you’ll be busy reaping the rewards of harvest. It’s also time to get out and start planting spring-flowering bulbs for next year and you can collect seeds for next summer’s colour too. Make the most of the remaining warmth while you can!
- Divide herbaceous perennials
- 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
- Keep up with watering of new plants, using rain or grey water if possible
- Start to reduce the frequency of houseplant watering
- 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
