Our full guide to all of the jobs to do in the garden in SeptemberWhat to do in the garden in September
September is a glorious month in the garden and a time for harvesting. While the weather can fluctuate in temperature, it's possible to experience chilly mornings or some late summer sun, so it's better to prepare for anything!
On less than lovely days, you could spend some time organising the shed or greenhouse in preparation for overwintering tender plants, so roll your sleeves up and give it a good scrub ready for the months ahead.
As summer bedding and hardy perennials die back this month, remove all dead growth and check for signs of disease. If you find any diseased foliage, we recommend burning it to prevent it from spreading further and add the non-diseased plant material to your compost heap, if you have one!
If you'd like more blooms in spring, it's time to finish planting spring bulbs, but wait to plant tulip bulbs until November.
For the full list of jobs to do in the garden this month, take a look below.
