Although autumn unmistakably arrives this month, the huge availability of tender perennials means we can all ensure our gardens remain colourful for a few more weeks.
Dahlias really come into their own, along with salvias, cannas and other exotics. Crocosmias, perennial asters and Japanese anemones are easy choices for colour in the border.
The weather in early September can often be warm and sunny, but by the end of the month it is often unsettled with rain and strong winds. Frost may strike, so gardeners need to be prepared to move tender plants to their winter quarters. Cacti and houseplants should be brought inside at the beginning of the month.
