Seasonal Calendar

Knowing what grows well in your garden and when is really important. With 12 months a year and lots of fruit and veg on offer, remembering what, when and where can be tricky. That's why we've put together this seasonal calendar. You can check what you could be growing this month, and what you should be planning later in the year.

Gardening in December

Gardening in December

We’ve put together a detailed list of jobs that can be done whilst you’re gardening in December:

 

Vegetable Garden

Time for winter preparation. Clear away the remains of old crops to tidy up the garden and prepare the area for next year. Add the material you gather to your compost heap. Spread a layer of compost over the cleared soil and fork it into the surface.

Bedding Plants

Plant pots of Cyclamen in several shades of red or pink to create a bright, beautiful festive display.

Bulbs

Plant bulbs in pots for spring bloom and brighten up the last few days of winter.

Climbing plants

Cut back summer-flowering Clematis to a pair of strong buds to be sure of good growth in the summer. On grapevines prune side shoots and cut back developing main stems by half their new growth to maintain a good shape.

Containers

Line wire baskets and fill them with bulbs for spring flowering. Insulate your pots with bubble wrap. Move any tender plants into a sheltered place, like a porch or greenhouse to help get them through the worst of the winter weather.

Fruit

Protect your fruit trees from winter moth grubs by applying a grease band to your trees now to stop an infestation next year. Prune out dead or diseased gooseberry stems, and any crossing in the centre. Shorten new growth by half to maintain an acceptable size.

Hedges

Continue to plant bare-root deciduous (seasonal leaf) hedging plants and trees.

Houseplants

Try using Poinsettia inside for a festive feel (they’re available in Homebase stores).

Perennials (winter surviving plants)

Add Hellebores to your shadier borders for beautiful winter flowers between January and late March (you can buy them from stores in mid-November). Be on the lookout for any pests on plants over winter. Small infestations of Whitefly, Red Spider Mite and Greenfly can soon spread.

Roses

Cut back tall stems on bush roses by half to help guard against wind damage, and shorten all the branches on standard roses. Plant bare-root plants as long as it’s not frosty.

Shrubs

Re-firm the soil around cuttings if the ground has been lifted by frost. Continue to take shrub cuttings (good ones to take are Forsythia and Buddleia). If a shrub has outgrown its space in the border, there’s still time to move it to a better location while it’s dormant.

Trees

Young trees may need pruning at this time of year to ensure they maintain shape and size. Remove any weeds from around the bases of young trees, as they compete with the plant for moisture and nutrients.

Vegetables

Sow early broad beans. Prepare your soil beds for next year.
