1. Prepare the Soil

Remove all the weeds and indulge in a wee bit of forking to maintain a tidy and uniform surface.

Also, it would be a good idea to add a few centimeters of compost layer or well-rotted manure over your topsoil to prepare it for the upcoming growing season.

Cover the newly prepared soil with multiple sheets of black plastic to keep it warmer and drier in preparation for the planting of summer-special seeds. It is one of the most important Things to do in March in the Garden.

2. Grow Typical Summer Vegetables

As long as the soil isn’t too waterlogged and soggy, early sowing may be done by slightly warming the soil. Using cloches for seed sowing ensures better seed germination results.

  • The warm and dry soil characteristic of mid-March is suitable for sowing beetroot, artichoke, brussels sprouts, carrot, cabbage, lettuce, parsley, spinach, radish, and broad bean. Additionally, you can also carry out the sowing of cucumber, aubergine, and other tender vegetables in a heated greenhouse.
  • To ensure a generous supply of parsley in the later months of the year, consider sowing the seeds in pots. Chives, on the other hand, are best grown individually.
  • Also, it’s advisable to sow outdoor varieties at the end of March, as they can grow better by taking advantage of the warmer conditions and becoming ready for planting out in June.
  • However, you don’t have to wait that long to grow seed potatoes. Just set them out in trays and place them in a cool, frost-free environment to enable the formation of new shoots.
  • If you have a soft spot for celery, sow the seeds in pots and place them in the greenhouse so that you have plants ready for outdoor growth by summer.

3. Don’t Forget to Prune!

March heralds the end of the dormant winter season. This makes it an ideal time for pruning all your trees and shrubs, with one exception–pines. Allow their new growth to expand and flourish until the young needles turn half of the full size before pruning. It is one of the most important Things to do in March in the Garden.

  • However, spring flowering shrubs, including lilac and forsythia, can be pruned now unless you don’t want to lose the flower buds on the delicate stems you are removing. If overgrown, these shrubs may be rejuvenated by cutting all the stems to the ground level to stimulate nascent ones to emerge. It’s important for you to perform the process now and don’t delay it until the flowering is done.
  • Elm, birch, maple, and black walnut tend to ooze sap when pruned in late February due to the effect of water pressure on the bottom layer of moist soil. While this won’t harm the plant per se, you can consider pruning these trees in the second week of March.
  • If it’s the beginning of the growing season in your zone, it’s the time to prune your evergreen herbs as well. Check out our herb pruning guide to learn more.

4. Plant Fruit Trees and Shrubs

As the pruning of established shrubs and trees should have been done by now, it’s a fairly accurate time for planting fruits and shrubs.

  • Plant apple and cherry trees in a sunny yet sheltered spot, and carry out late plantings of soft, succulent fruits such as raspberry, gooseberry, and strawberry.
  • Cut canes of raspberry to ground level to stimulate new canes, which will eventually go on to fruit in fall (autumn). Also, ensure to feed your blueberry shoots with ericaceous plant fertilizer.
  • Mulch rhubarbs with a thick layer of manure to keep them healthy and reduce moisture loss from the soil.
  • It’s also a good time to plant fresh rhubarb crowns, though you should ensure not to cover them up with manure. With that being said, it’s recommended to cover the crowns with used-up buckets to exclude any light and trigger the development of long, tender rhubarb stalks.

5. Plant Bulbs

This is the time when early flowering bulbs like caladiums, dahlias, crocus, and hyacinths should be taken out of storage to leave the foliage to break dormancy naturally. It is one of the most important Things to do in March in the Garden.

  • Plant tender bulbs of begonia tubers in a pot containing moist compost, covering only the top. These pots should be ideally kept in well-lit spots and occasionally watered whenever the growing medium dries out. As soon as the shoots elongate, they should be potted individually.
  • You can also start potting up stored geraniums. The warm, sunny days help stimulate new growth and lead to fuller plants by the time summer arrives.

6. Install Rain Barrels/Water Butts

You can also consider installing compact little water butts/rain barrels in your garden for collecting the rainfall.

In addition to helping the environment, rainwater is great for watering ericaceous plants like Camellias, blueberries, and rhododendrons.

One thing to make sure of while installing this is that it’s positioned below the downpipe in a bid to take maximum advantage of the rainfall.

7. Eliminate Garden Pests

Eliminating hibernating pests in the early days of March can save you a world of trouble in the upcoming months of summer. It should top your list of Things to do in March in the Garden.

  • Examine the crowns of your perennial plants, and you will find slugs, snails, bugs, and aphid colonies cowering in the closed spaces, sheltering for the winter.
  • In case you still haven’t cleared up the former year’s pots of summer bedding, then you better do this now and watch out for the weevil larvae, which tend to thrive on compost and feed on roots. Destroy any you come across, and gear up to kill off vine weevils this year with chemical drenches or parasitic nematodes.

8. Move Deciduous Shrubs to Right Spot

If you have a poorly placed deciduous shrub or two, now is the best time to move them while they are still dormant. To prevent the roots from drying out, choose a still day.

  • When digging them up, take a wide berth all around the shrub and try taking as much of the root as possible for faster establishment in the new location.
  • Also, ensure planting the shrubs at the same level as they were previously in the soil. And don’t forget to water them generously afterward!

9. Groom Your Lawn

Nothing spoils the beauty of a well-maintained garden bed more than a worn-out lawn lying alongside. Lawns suffer from the build-up of moss, debris, and plant decay in the dreary days of winter, so March is probably the best time to tackle it. It is one of the most important Things to do in March in the Garden.

  • You can start by hauling out all the dead grass, moss, and clutter that has accumulated. If allowed to remain, they can quickly condense to form an impenetrable waterproof layer over the topsoil.
  • Additionally, ensure to dig out the roots of perennial weeds by using a weedkiller. If the lawn is already established, proceed to make the first cut of the season; but before proceeding, ensure the grass is not too wet.

10. Pay a Final Tribute to Winter

Get your cool-season favorites into the garden now. If you wait, the weather will get warm to grow them. Have homemade windbreaks or row covers handy to protect them on windy days and chilly nights.

  • Early on, sow the plantings of turnips, beets, mustard, broccoli, and spinach. Then in mid-to-late March, plant peppers, cucumbers, tomatoes, corn, and squashes. Nurture young plants with organic fertilizer. Also, pull away from the mulch from shrubs, trees, and perennials to allow the soil to become warm around them.
  • At the end of the month, plant seasonal ornamentals, including daisies, marigolds, carnations, and petunias.
