March

  • Prune back autumn flowering clematis and lift and divide overgrown clumps of perennials.
  • Take the old flower heads off winter flowering heathers and trim the plants to shape.
  • Deadhead daffodils then let the foliage die down naturally so it feeds the bulb and produces an even better display next year.
  • Finish pruning roses and feed rose bushes.
  • Steep freshly-cut nettles in water for a few weeks and decant the rich brown liquid for a potent, nitrogen-rich plant food.
  • Protect new spring shoots from slugs.
  • Plant shallots, onion sets and early potatoes - Plant onion sets around 10cm apart, sinking the sets just below the soil’s surface.
  • Weeds are set to make a come-back. Now is the time to deal with them before they get out of hand - Start hoeing weekly to catch annual weeds the moment they appear so they never get big enough to bother you or your plants.
  • Start using ponds and fountains etc again and remove pond heaters.
  • On warm days, open the greenhouse or conservatory doors and vents and keep a look out for fungal diseases.
  • On dry days, start mowing the lawn again but keep blades on highest setting.
  • Plant summer-flowering bulbs.
  • Mulch Raspberry canes with compost or manure.
  • Now is your last chance to plant bare-root fruit bushes and trees.
  • In warmer areas, spray Peaches and Nectarines to help control Peach leaf curl.
  • Sow seeds of beetroot, leek, lettuce and summer cabbage in a heated Greenhouse.
