Gardening in September

Raspberries

Late summer progresses into autumn

September is 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!

Top gardening jobs this month

Divide herbaceous perennials

Dividing perennials regularly will ensure healthy, vigorous plants that will continue to perform year after year. It also offers the opportunity to multiply your plants

Pick autumn raspberries

Harvest regularly, to get fruits at the peak of ripeness, when richly coloured, plump and easy to pull off. Pick on a dry day, so the berries aren’t wet.

Collect and sow seed from perennials and hardy annuals

Growing plants from seed is generally straightforward and inexpensive. It is an opportunity to increase the number of plants in your garden for free.Grow plants for seed
