In the Vegetable and Fruit Garden
Check your winter protection structures are still securely in place.
Prune open-grown apples and pears (but not those trained against walls).
Harvest leeks, parsnips, winter cabbage, sprouts and remaining root crops. Prune currants and gooseberries.
Plant new fruit bushes and trees - as long as the soil isn't frozen or very wet.
Apply fatty acid-based winter washes to dormant fruit trees, to control over wintering pest problems, such as aphids, apple suckers and scale insects. You will need to access all the nooks and crannies where they hide.
If you have not done so already, now is the time to dig over and incorporate soil improvers into vacant areas of the vegetable plot. You can cover these areas with thick polythene to keep the soil dry and make it easier to work in the spring - particularly useful for heavy clay soils. Clear polythene will increase the soil temperature, enabling earlier sowings in spring. Black polythene will suppress weeds. Clear late-season debris off the vegetable plots, and dispose of it as advised below.
Bulbs and Herbaceous Plants
Slugs can still pose a threat, and slug controls are necessary now, as always.
On the Lawn
Continue to remove fallen leaves from lawns before they block out light and moisture to the grass. Repair damaged lawn edges or patches with turves cut from other areas of the garden. Avoid walking on lawns on frosty mornings. It can damage the grass and often leads to brown footprint-shaped marks. Watch your lawn for signs of water-logging, as the weather gets wetter. You may be able to remedy this with some maintenance - either now, next spring, or the following autumn.
The Shrub Border
Prune Acers, Birches and Vines before Christmas to avoid bleeding.
Check tree stakes and ties, adjust and/or replace where necessary. Take hard wood cuttings.
Digging-over in winter exposes soil pests to frost and bird predators.
Frost will help improve soil structure.
In the Glasshouse and Conservatory
Check that glasshouse heaters are working. Reduce watering of houseplants. Keep an eye out for over wintering pests such as whitefly or red spider mite and treat accordingly.
Ponds
Prevent ponds and stand pipes from freezing. Regularly shake off leaves from nets over ponds to prevent them from building up. Rake out fallen leaves from un-netted ponds before they sink.
Roses
Plant roses, but avoid areas where roses were previously grown as this can lead to problems with replant diseases.
The Compost Heap
Compost all green waste.
Recycle
Paper (wrapping Paper), Cardboard (Christmas cards, Gift boxes etc), Glass Bottles and Jars, Plastic.
There are many recycling points throughout Glasgow where clothes, shoes, furniture, rubble, electrical goods etc can be disposed of without charge.
Use recycled products/materials where possible.
Collect rainwater and investigate ways to recycle water for irrigation.
Be water wise, especially in during long dry spells.
Others
Deciduous trees and shrubs can still be planted and transplanted.
Take hardwood cuttings.
Keep mice away from stored produce.
Clean and store bamboo canes in the shed (or other dry place) to ensure they're still in good condition for next year. Broken ones can be shortened, where possible, for re-use.
