What to do during January in your garden and greenhouse.
Your monthly gardening checklists
Flowers
- Plant bare-root roses, shrubs, hedging and ornamental trees, as long as the ground isn't frozen
- Take root cuttings of fleshy-rooted perennials such as oriental poppies, acanthus and verbascums
- Establish new colonies of snowdrops and hellebores by buying plants in flower, so you can choose the prettiest blooms
- Clear away soggy, collapsed stems of perennials and compost them
- Take hardwood cuttings from deciduous shrubs, such as forsythia, willow and viburnum
- Remove and bin hellebore foliage marked with black blotches, to limit the spread of leaf spot disease
- Press mistletoe berries into the bark of apple trees to establish your own mistletoe plants
- Check that small alpines don't become smothered by fallen leaves and other wind-blown debris
- Deadhead winter pansies and other bedding regularly, and remove any foliage affected by downy mildew
- Move dormant plants that are in the wrong place to more suitable sites
- Check for rot on stored bulbs and tubers, and ensure dahlia and canna tubers haven't totally dried out

Plant snowdrops

Fruit and veg
- Winter-prune apple and pear trees to remove any dead, damaged, congested and diseased branches
- Sort out your seeds, throwing away empty or out-of-date packets and noting down any to buy for the coming season
- Plan this year's crop rotation to ensure you grow each type of crop in a different bed to previous years
- Prune gooseberries and redcurrants, cutting sideshoots back to three buds from their base
- Clear old crops and weeds from the veg plot, then dig over the soil, mixing in compost as you go
- Regularly inspect stored crops, discarding any showing signs of rot or deterioration
- Plant bare-root fruit bushes and trees into enriched soil, as long as the ground isn't frozen
- Ensure netting is in place over brassicas, such as kale, Brussels sprouts and cabbages, to protect from pigeons
- Cover rhubarb plants with a bucket or terracotta pot to force an early crop of tender long stems
- Feed spring cabbages with high-nitrogen feed to encourage leafy growth
- Prune blackcurrants, if you haven't done so already, removing about a quarter of the old stems
- Order seed potatoes, onions, shallots and garlic bulbs for planting in spring
