1Increase your bulb collection
Divide and/or plant bulbs-in-the-green, such as snowdrops (Galanthus) and winter aconites (Eranthis hyemalis).
2Start dahlias into growth
Dahlia tubers stored over winter (or bought this year) can be started into growth. Place them in a light, warm place to sprout before planting. They will need misting with a spray bottle to stop them drying out.
3Prepare alpines for spring
Top dress spring-flowering alpines with grit or gravel to show off the plants and to help prevent stem rots. Remove dead leaves from around the basal rosettes of alpine plants to prevent rotting.
4Improve shape of Mahonias
Cut out the top rosette of leaves from the leggy stems of Mahonia x media cultivars to encourage branching.
5Veg to sow now
In cold frames, greenhouses or polytunnels, sow beetroot, broad beans, summer and autumn cabbage, carrots, kale, leeks, lettuce and spring onions. These can all be sown in trays or plugs to be planted out towards the end of March.
