September in the Garden – The Start of Autumn
Summer is drawing to a close and Autumn is just around the corner – what a perfect time to think about planting – the soil is warm and the Autumn rains will get plants established before the Winter sets in. It’s also a good time to take stock of your garden and think about any changes or plans you want to make.
Keeping colour in borders for as long as possible is top of the ‘to do’ list for September, so you may like to consider incorporating late Summer or Autumn flowering plants such the Aster. The name Aster comes from the ancient Greek word for ‘star’, although they are often referred to as Michaelmas daisies because of their typical flowering period in the Autumn. Asters come in blue, purple, red, pink and white each with a yellow centre. There are numerous varieties of Aster, from dwarfs that measure less than a foot to tall versions that can reach up to eight feet. All varieties make for good cut flowers and are easy plants for beginners to try in the garden. They thrive well in drained, fertile soil that retains moisture and prefer full sun or partial shade.
It’s also the time of year that nurseries and garden centres have great offers on big bags of mixed Daffodil bulbs, in all shapes and sizes. They can grow pretty much anywhere, even through the lawn. The easiest way to work out how deep to plant your bulb is to dig down approximately three times the depth of the bulb – but be warned, if you plant Daffodils too close to the surface they often won’t flower. You can plant Daffodils, and Crocuses, from September to October – as many as you can get into the ground or in containers. Once planted you need do nothing else to them other than wait for a stunning show in the Spring. If you’re planting in lawns, cut out three sides of a square and lift back the turf, put in a few bulbs and then firm the turf back again.
As it’s bulb season, you could also plant hyacinth bulbs in pots, by mid-September, so that you have a glorious Christmas display – creating a scented centrepiece or gift for gardening friends and family. Once the hyacinths are planted in a pot, put in a dark cool place (a garage or shed) for 10-12 weeks and then bring out into the light so flowering can start.

• Look after your lawn – weed it and seed it
