It marked the boundary between summer and autumn, the end of the summer bedding and the start of winter bedding plants, as well as the busiest time of year for planting trees and shrubs.
The main growing season is coming to a close, but your garden still needs you.
Summer bedding plants will likely last for another few weeks, so there is no rush to throw them away.
In general, summer bedding will last until the first frost and you can choose to leave them until this time or start to replace them now.
When it comes to winter bedding, there is not the same number of options as summer.
The colder temperatures mean that many plants cannot flower or the flowers do not last as they are hit by cold winds and freezing nights.
Winter pansies, violas, primrose, and certain cyclamen will be quite happy in the exposed cold and although you may lose the odd open flower during the cold, they will re-grow.
Autumn Chrysanthemums are a great option and will flower profusely well into autumn.
Part of being a gardener involves thinking ahead and planning for these months of the year where bright colour is not as easy to come by.
Flowering bulbs can provide an easy and relatively cheap answer to many of your problems.
Bulbs, or corms as they are also known, need to be planted months before they flower, so autumn flowering bulbs are planted in spring and spring flowering bulbs are planted in the autumn.
Mail order bulbs, and mail order plants in general, should be avoided as living plants cannot be transplanted in this method without suffering some side effects.
Spring flowering bulbs are available to buy in garden centres now and I would recommend you buy them as soon as possible.
Because they are grown specifically for sale there are produced in fixed numbers.
That means once a garden centre sells out of a variety we often cannot buy more.
Trust me, after a cold, hard winter I guarantee your mood will improve when you see the first daffodil or snowdrop poke its wee head through the soil and you know spring is on the way.
