What To Do In the Garden This Weekend - March 5th

Published on March 5th 2020

Weeds can quickly get out of hand if you don't keep on top of them. Before things get hectic in the garden, it's good to have a bit of a blitz! This week I'm also recommending that you look after early flowering bulbs so that next year they will be even better.


  • Get on top of weeds now as they are about to make a serious growth spurt! Remove by hand or, if weeds are deep-rooted perennials, you may want to spray with an appropriate weed killer.

Cultural tips

  • Top dress alpine plants with horticultural grit. This ensures fast drainage around the base of the plant and mimics natural conditions.
  • Use branched pea sticks or buy plant supports and place them around perennials that will later need support. It's much easier to do this before new soft growth begins.

  • If you have access to hazel trees then this is the time to get bean poles. You'll need to ask the owner's permission if they're not yours!

  • Increase the frequency of houseplant feeding to fortnightly. Use a high potash feed (Miracle-Gro or Phostrogen) on plants grown for their flowers and a high nitrogen feed (Baby Bio) for plants grown for their attractive leaves.

  • Lift clumps of crowded snowdrops as soon as the flowers fade. Carefully divide them and avoid breaking their delicate roots as you do so. Replant immediately. Leave the seed heads on them as, with luck, these will produce new plants too.

  • When they finish flowering, remove daffodil flower heads to stop them from wasting energy on seed production. Do not cut off the leaves until they turn yellow and don't even think of tying them into knots! Use a liquid with tomato fertiliser to help next year's flowers to form. Check for snail damage too.

Pest and Diseases

  • Yellow lower leaves on brassicas should be removed regularly. Sprouts, cabbage, kale and purple sprouting may be suffering from downy mildew and can infect new crops. There is currently no good chemical control for downy mildew.

  • Protect young seedlings and newly emerging soft shoots from slugs and snails. In particular check Delphinium, Hosta, Gypsophila and lupins.
