March…in your garden

Well here we are again – the months are flying by here at Thorngrove and I’m back again with some gardening tips for March!

  • Did you start chitting your potatoes last month? Now is the time to get your first earlies planted either in the garden or if you don’t have space grow some in a potato sack or large pot. They really are worth the effort – there’s nothing like digging up your own potato!
  • Protect new spring shoots from slugs especially things like lupins and delphiniums – we have pest control products available.
  • Plant your onions and shallots – also available here!
  • You can now plant your dahlias gladiolas and lilies.
  • Weed and top dress your containers top up with fresh compost .
  • Lift and divide overgrown perennials like Leucanthemums Alstroemerias  (day lilies) etc
  • Mow lawns on dry days if needed, if you have moss problems apply moss killer mid March then scarify early April. When the moss has died, if its only a small area you can use a metal lawn rake. If it’s a large area use a motorised scarifier.
  • If  you have a pond with fish in it you can start to feed them because the weathers warming up so the fish are starting to come up to the surface again.
  • Prune your Bush and climbing roses.

Sowing and planting

  • Hardy annuals Can be sown in pots or modules to give you colour in the garden. In mild areas you can sow directly outside marking out irregularly shaped seed beds and broadcasting drifts of different seeds to give you a more natural look.
  • Sweet peas can be sown outside or purchase sweet pea plants from us at Thorngrove and plant out, making sure you protect them from slugs and snails.
  • Its also a good time to plant herbaceous perennials – here at Thorngrove we have a large selection to choose from.
  • Cut back ornamental grasses and other perennials left for winter interest if you have not already done so, even if they look good you need to do it to make way for the new growth!
  • Perennials putting on lots of new growth may need supporting – this will probably be towards the end of the month.
  • Check whether containers need watering, even at this time of the year they can dry out especially if they are protected by the eaves of the house.
  • Also watch out for Aphids as they can soon multiply during mild spells.

Enjoy yourselves out there, and if you need any further advice about your garden space, just stop by for a chat!
