September is more of a cooler, gustier month than August and you can start to notice days becoming shorter. While there's not as much to do in the ornamental garden at this time of the year, but you will be reaping the rewards of harvest from any fruit or vegtable patched you may be maintaining.
Top tips to remember this autumn:
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
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!
