March Newsletter – Suttons Gardening Grow How


All Nature seems at work.  Slugs leave their lair. The bees are stirring, birds are on the wing, And Winter slumbering in the open air, wears on his smiling face a dream of spring.”


~ Samuel Taylor Coleridge

As we move into March, it is the month where spring is finally among us. Although wrapping up in your favourite jumper and going on a windy walk has its perks, we are seeing a glimpse of summer on the horizon which we have all been waiting for. According to the Met Office, the 1st March heralds the start of spring whereas astronomically it doesn’t arrive until the Spring Equinix, which this year falls on 20th March. So perhaps we are being a bit optimistic. The Spring Equinox is when the day and the night are of equal length but when we sun we see the sun!

So, we can start getting excited from 1st March onwards but not until after the Spring Equinox will the days lengthen and the nights shorten, giving us all more time to spend in our gardens. We tend to think it’s the increased daylight that makes our plants spurt into growth but in fact, it is the shorter nights.

Of course, spring is not just the name of the season, it is also an active verb. With lighter mornings we can spring earlier from our beds and start to make our gardens look wonderful, with the promise of summer ahead.

This month is the beginning of the peak gardening season. Sowing flower seed should be at its height now, plus it is also the start of the main sowing season for vegetables outdoors. Early flowering bulbs will require some attention this month. As long as weather conditions allow preparation for lawns can begin. Gardens could very well need a general tidy-up at this time and keep a lookout for any weeds that are beginning to appear.

In this month’s March newsletter, we are going to be taking you through handy March garden tips, seeds to sow including flowers and veg, this month’s offers, gifts for Mothers Day and much more.

Every month we like to give you the best tips in the garden there is. In this month’s March newsletter, it looks like there’s plenty to all over the garden including mowing the lawn and preparing your summer flowering bulbs!

  1. As your long-awaited daffodils start to fade, strengthen the bulbs for next year by snapping off the deadheads. Don’t be tempted to remove the leaves, untidy as they may look, they really do need to be left to die down naturally if you want a good display next year.
  2. As spring bulbs come to an end now is the time to plant summer flowering ones, including lilies, anemones, dahlias, begonias and gladioli. Wait until the soil begins to warm and choose a sunny spot in free-draining soil. Summer bulbs will also do well grown in pots. Remember to plant at 2 to 3 times the depth of the bulb.
  3. Sow tomato seed this month and you’ll be picking the fruits by the end of June. Early varieties of tomatoes will develop well on plants when grown under glass in a heated greenhouse. For quick germination, it is best to sow the seed in a heated propagator or you could use a windowsill. It is best to sow outdoor varieties later in the month and the plants are potted on as they grow, ready for planting out in early June.
  4. Shallot sets can be planted this month, spacing at 15cm (6″) intervals in rows 30cm (12″) apart, and once conditions have warmed up, generally towards the end of March, onion sets may also be planted.
  5. Cut down any perennials left from last year so that new growth can form. Now is the time to put supports in place for the plants to grow up and through.
  6. Sow, sow, sow! March is prime seed sowing time so make sure you’ve got the seeds you want, plenty of seed trays and compost and then get started. Hardy annuals can be sown directly where you want them to flower.
  7. Lawn mowing starts this month, depending on the weather! Set the blades nice and high and remember to skirt around any clumps of bulbs. Neatening the edges of the lawn will give the garden an instant lift.
  8. The deadheads on hydrangeas will have provided the plant with winter protection but can now be removed. Using sharp secateurs, cut the stem back to the first strong, healthy pair of buds down from the dead flower.
  9. Plants growing in containers will need regular watering from this month onwards and some will need repotting. If the plant is too large to repot simply carefully remove some of the top compost and replace it with fresh.
  10. Seed potatoes should be set out in trays which are placed in a bright but cool, frost-free situation so that the shoots will form. Plantings of early varieties can be made during March, however, main crop varieties are best planted in April.
