March In The Garden


This is the time to spread mulches of bark or compost over flower beds, check borders for weeds and tackle any problem areas before they have chance to get established. The really nice thing about tackling those gardening jobs is the smug sense of achievement when your garden looks tidy and ready for the growing season. So what other things can you do this month?

Flower Garden

Flower Garden

  • Prune rose bushes
  • Trim winter-flowering heathers to neaten the plants and remove faded flowers
  • Cut down old growth on penstemons, leaving new shoots around the base
  • Lift and divide congested clumps of snowdrops.
  • March is also a good time to buy new snowdrops ‘in the green’
  • Prune winter jasmine after flowering to control growth
  • Prepare the soil for sowing hardy annuals in April
  • Plant out gladioli, lilies and other summer bulbs
  • Start spraying outdoor peach and nectarine leaves to prevent peach-leaf curl
  • Prick out seedlings from previous plantings
  • Choose new herbaceous plants
  • Lift and divide established plants
  • Sow half-hardy annuals and alpines under cover
  • Plant gladiolus and other corms
  • Take cuttings of chrysanthemums, fuchsias, pelargoniums and dahlias under glass

  • Plant first early potatoes in mild areas where the soil is workable
  • Spring prune fruit trees like Peaches and Nectarines
  • Sow some Sweet Peas to grow alongside your Runner Beans
  • Plant more onion sets and also some more shallots
  • Spread some wood ash or high potash nutrient on raspberries and strawberries.
  • Sow Lettuce, Parsley, Coriander, Basil, Red Cabbage and Cauliflower in the cold-frame
  • Sow some Tomatoes, Chilli Pepper, Aubergine and Bell Pepper in a heated propagator
  • Sow Radish, New Zealand Spinach, early Carrots directly in the ground in milder areas.
  • Sow Peas in guttering at two-week intervals – place in cold frame or under fleece.

If you don’t have a cold frame, try sowing peas in lengths of guttering and then tucking them up with a double layer of fleece. That way they have a better chance of germination and also when it comes to planting them out on the plot all you do is water them, then slide the whole thing out into a trench. Very easy!
This video shows you how to plant Peas after using a piece of guttering to get them off to a faster start. If you suffer from mice eating direct sown pea seeds in your garden this should stop this happening.


General advice

  • Spread mulches of bark or compost over flower beds
  • Check borders for weeds and tackle any problem areas before they have chance to get established
  • Cut back any overgrown ivy
  • Build a compost heap, or buy a new bin to allow you to recycle more kitchen and garden waste

Keep your eye on the weather. There’s little point in sowing or planting when cold weather is forecast.
