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!
