Get ready for some vivid garden colour next season – 2018 has been named the Year of the Marigold.

Fleuroselect, the international organisation for the ornamental plants industry, promotes a flower and vegetable every year – it’s basically a huge marketing exercise.

JOBS FOR THE WEEKEND

Turn compost heaps and tuck them up for winter.

Tree peonies and camellias will benefit from bonemeal and a top dressing with compost.

Cut back and remove dying foliage from pond edges, and net pond if you haven’t already done so.

Apply grease bands to fruit trees and their stakes.

Stack shredded leaves before using them as mulch – root veg patches love this!

Remove mulch from around soft fruit bushes to expose pests. Burn debris.

Remove saucers from under container plants to prevent frost damage.

Harvest orchard fruit - store only those in perfect condition.

When you are tidying borders, don’t cut back any more tender plants. Mulch them deeply to protect them against a hard winter.

Plant new rhubarb crowns.

Plant herbaceous perennials and clematis and autumn-flowering cyclamen will establish well if planted now while they are in flower.

Prepare bean trenches for next spring, with veg waste and cardboard/newspapers.

Remove leaves from gunneras and use them to cover the crown to protect from frost.

Cover parsley with cloches so that it crops through winter.

If you’ve got tender plants, bring them indoors before they get killed by the frost. Choose a light, frost-free place such as a greenhouse or coldframe. Keep them on the dry side during the winter, so they don’t put on much growth.

If you haven’t done so already, lift all your maincrop potatoes on a dry day and store in bags in a cool dark place. Don’t leave them any longer or the slugs will find them.

Leave bean plant roots in the soil – they add nitrogen and can be dug in later.

Cut back old wood on blackcurrants and gooseberries, and remove any wispy growth.

Once all the fruit has been picked, let the birds into your fruit cage to pick off any pests.

Plant daffodil and crocus bulbs. Tulips can wait until next month.
