December

Let's face it - most people don't venture out into the garden this month unless it's to cut evergreens for Christmas decorations or to put out bird food. December weather is often cold, wet and windy. There may even be snow. Winter jasmine is a star performer, covering its green shoots with starry yellow flowers, however dismal the weather.  Hopefully you can still enjoy your garden from the warmth of your living room.

ESSENTIAL JOBS CHECKLIST FOR DECEMBER

Last Chance To…Do your Christmas shopping!

Flower Garden
If you're feeling energetic get out and do a bit of digging. Start a programme of conditioning and improving your soil. To do this successfully you need first to find out what sort of soil you've got, whether it's acid, neutral or alkaline, whether it's sandy, peaty, stony, loamy or sticky with clay. If you're new to gardening ask your neighbours. Buy a soil testing kit - this will measure the acidity of your soil. Any soil will benefit from having organic matter added so while you're digging add plenty of  Farm Manure.  As long as the weather remains dry you can continue planting evergreens.
Curl up in front of the fire with lots of colourful catalogues to give you lots of ideas for next year.
Clear up any fallen leaves and cut back perennials if you haven't already done so.

Roses
Bare-rooted roses can be planted this month. 

In the Greenhouse
Potted azaleas need to be watered with rainwater. Feed them weekly with Liquid Ericaceous Feed and stand them on damp gravel. When they form buds you can take them into the house if your prefer but continue to treat them in the same way. They do prefer to be kept on the cool side.
Save energy and keep your greenhouse warm by lining it with bubble pack
You may think pests are dead or hibernating but unfortunately whitefly and greenfly find greenhouse very congenial all the year round. Be on the lookout for them and spray as necessary.

Lawn
Clean your lawn mower and think about getting it serviced. When spring comes you'll be glad you did.

Containers
Trees and shrubs can be planted in containers in fine weather. For permanent plantings like these choose John Innes No. 3 or John Innes Ericaceous Compost.

Vegetable Garden
Clear away the remains of old crops and put them on your compost heap. Remember to add Garotta biological compost maker every 15 cm (6 inches).

Herb Garden
Protect bay in very cold weather or if it's in a container move it to a sheltered spot.

Fruit Garden
Take hardwood cuttings of currants and gooseberries. The cuttings should be about 25-30 cm (10-12 inches) long and should be buried in a trench in the open ground to about half their length.

Water Features
Keep an area in pools and ponds ice-free to stop the build-up of gases that could harm wildlife. Never smash the ice. Melt it by standing a pan of boiling water on it.

Alpines
Now's the time of year to sow those seeds that require exposure to the frost to promote germination. Use small pots of John Innes seed compost with added grit where required and cover the seeds with Silvaperl Grit Sand. Stand the pots out of the sun.
