March
Frosts can still be a hazard, so keep vulnerable plants protected at night if frost is forecast. March winds are also notorious for their ferocity so check exposed plants are well supported.
Now is the time for a thorough spring clean; weed and dig over your borders incorporating as much organic matter as you can - those chilly winds will really help to dry out the soil. Mulch bare soil once you have done the work and remove moss and weeds from paths, terraces and driveways. They may be boring tasks but if you don’t get on top of the garden now (especially the weeds!) it will be a nightmare for the rest of the season.
Make new beds and borders – mark the shape with sand trickled from a bottle, remove the top layer of growing vegetation and dig the ground over, incorporating as much organic matter as possible. If you are making a bed in the lawn, remove the turf – if you dig it in the buried grass will regrow and regrow and regrow and................
Clean and repair your garden tools, book the lawn mower in for a service and check garden furniture for any rot. When it is warm enough, treat sheds, fences and trellis with wood preservative; brushes and rollers are fine for most things, however a sprayer is well worth buying for tricky projects such as woven panels!
TREES, SHRUBS, CLIMBERS
Plant container-grown roses, shrubs and climbers (remember to plant climbers about 10” away from walls so they are not in a rain shadow) and give overgrown climbers a tidying haircut. Remember, this is absolutely the last chance for planting bare-rooted roses – when the buds have broken it is too late.
Prune modern bush and shrub roses, colourfully stemmed dogwoods and willows and Buddleja and ornamental elders.
Move evergreen shrubs.

LAWNS
If it is very wet keep off the lawn as much as possible – damage to waterlogged lawns is easily inflicted and irritatingly hard to rectify. When the weather improves and the lawn has had a chance to dry out, give it a first cut with the blades on the highest setting – don’t be tempted if conditions are wet! Reseed bare patches, neaten the edges with a half moon cutter or spade and remove molehills and wormcasts. If you are planning a new lawn, start preparing the ground for seeding or laying turf. Ask for advice in your local garden centre if you are unsure as to how to begin.
BULBS, FLOWERS AND CONTAINERS
Protect new spring shoots from slugs....
Plant summer flowering bulbs and snowdrops and winter aconites ‘in the green’ – ie when the plant has finished flowering but the foliage is still present and green. Neither takes kindly to being planted as dry bulbs. Add some compost to the soil, a sprinkling of bonemeal and plant them slightly deeper than they were in the pot.
Lift and divide overgrown clumps of perennials and split polyanthus plants once they have finished flowering.
Sow hardy annuals in drifts – clashing colours just don’t matter in a garden, but remember to plant taller plants behind shorter ones.
Sow sweet peas outdoors (soak the seeds overnight to improve germination) and plant out those raised under cover.
Brighten up your pots and containers with tete-a-tete, pansies, violas, primroses, cyclamen and spring heathers. A stunning combination is tete-a-tete surrounded by pink and yellow primroses and variegated ivy - or try pansies densely packed for a striking display of colour. Plant flowering spring bulbs and primroses in empty gaps....a bit of a cheat, but who cares!
Remove the top layer of soil from pot-grown shrubs and replace with fresh potting compost that contains a slow-release fertiliser.
If the weather really does turn dry, remember pots and containers will need watering, especially if they are near a wall and in a sheltered position. Take care not to overwater.
