Start sowing hardy annuals
Sow hardy annual flowers where they are to bloom if your soil is workable, such as Calendula, Nasturtium and Nigella. You can also sow them in modules if you have space in an unheated greenhouse to give them a faster start.
Protect sweet peas
Check autumn-sown sweet peas and apply mouse and slug controls if necessary.
Give hedges, trees and shrubs a boost
Feed trees, shrubs and hedges with a balanced fertiliser (such as Growmore or blood, fish and bone), sprinkling it over the root area before hoeing into the soil surface.
Seasonal pruning advice
Delay pruning spring-flowering shrubs until after they have flowered. Don’t prune slightly tender evergreen shrubs (such as Choisya, until April), but do tackle hardy types. Remove reverted green shoots on variegated evergreens.
Renovate some climbers
Overgrown climbers can be renovated. Deciduous varieties will be at bud burst now, so you can tell which growth is dead and alive – suitable for Lonicera (honeysuckle), Hedera (ivy) and rambling roses.
