April Gardening Tips

April Gardening Tips
  • Hoe annual weeds that have risen and appeared in vegetable patches or perennial beds
  • Divide perennials and move into flowering positions
  • Trim lawn edges with a half-moon edging tool, this will keep the edges of lawns defined and tidy
  • Trim Lavender to keep it compact and bushy, using a good pair of sharp secateurs will ensure you keep a defined shape
  • Plant Tomato plants under cover now
  • Plant new season Roses and spray mature roses for aphids
  • Tie in climbers so that they do not get tangled as they grow
  • Sow Sweet Peas, Nasturtiums, Ipomea and Thunbergia for Summer colour
  • Protect Apricot, Nectarine and Peach flowers from frost
  • Mulch borders with bark chippings
  • Plant Alpines now
  • Apply slug pellets to borders, especially Hosta beds to prevent the new growth from being eaten
  • Sow seed Potatoes, Onion Sets, Garlic, Horseradish and Jerusalem Artichokes
  • Top dress borders with Fish, Blood and Bone fertiliser or pelleted poultry manure

Look out for Lily Beetle this time of year. They are bright red in colour and they devour the foliage on Lilies and Fritillaries weakening the plants.

To prevent damage spray with a good systemic insecticide, always reading the instructions for use on the label.

These beetles can be very clever as they fall to the ground and lay upside down on the soil, becoming camouflaged before continuing their damage. Therefore always ensure you return to the plant and re-check for their presence.
