Months

It's Spring so soon you will be able to see your garden coming to life. We have already left the winter months behind but March can still bring some cold days so remember to look after the plants that need protection from cold.


Flowers
  • Start pruning hardy late flowering shrubs.
  • Late summer flowering clematis (flowering from July onwards) need heavy pruning this month; they can be cut back to 3 ft above ground.
  • Sprinkle granular fertiliser round roses, shrubs and along the base of hedges.
  • Early flowering clematis (before June) will need to have all the dead foliage removed and be trimmed back to a healthy set of buds.
  • Now is a good time to prune and tidy up wisterias; if left they can get out of hand and may result in fewer flowers.
  • To prevent hellebore leaf spot spreading you should cut away old foliage on Christmas roses.
  • Plant summer flowering bulbs.
  • Check your flower beds for plants that may have lifted in the frost.
  • Sprinkle fertiliser over flower beds and around shrubs and roses.
Greenhouse
  • If you find seeds and plants being eaten we suggest you put a mouse trap in your greenhouse.
  • Clean the leaves of your evergreen houseplants, simply wipe them with a damp cloth.
  • To prevent grey mould infections forming pick faded or yellowing leaves from your plants.
Fruit & Veg
  • Fruit trees and fruit canes can now be cut back.
  • While pruning check all tree stakes and ties as winter winds may have loosened them.
  • Carefully dig away grass or plants growing close to the stems of fruit trees to reduce competition.
  • Plant out onion sets in rows, spacing them about 10-15cm apart .
  • Feed cabbages and other brassicas with or an nitrogen-rich fertiliser such as chicken manure.
  • You can now sow seeds of the following crops outside or under cloches: carrots, leeks, beetroot, cauliflower, turnip, cabbage, brussels sprouts, spinach, peas, and lettuce.
  • Dig out problem weeds and emerging annual weeds.
Around the Garden
  • Move plants from greenhouse to cold frame, to acclimatise to cooler temperatures before planting out
  • Treat emerging shoots of perennial weeds.
  • Replenish gravel and grit mulches around alpine plants.
  • Apply residual path weedkillers to paved and gravel areas.
  • Build new compost bins to recycle garden waste.
  • You may have lost 1 or 2 plants to severe frost so now is the time to remove anything that is not looking its best and replace it with something new.
  • Tidy up the garden shed and inspect all chemical bottles for signs of leakage - they may have frozen at some stage and upon thawing the bottle can often crack.
