Gardening Tips for March, Ideas, and Techniques

Introduction to gardening tips for March: March is an interesting month in the garden. While it is important not to rush into gardening and endanger the tender seeds or seedlings, it is also important not to miss these first days of hot temperatures, fertile soil, and abundant rains.

Although the exact dates of garden work will depend on where your garden is and what its needs are, all gardeners should consider these works throughout March. Spring usually falls by the middle of March and often sunny days provide an opportunity for an increasing range of gardening works. March month is the perfect time to prepare for seedbeds, sow seeds, cut winter bushes, and generally clean around the garden.

Flower gardening in March 

  • Pick any developing seed heads on Daffodils and other spring bulbs, but leave foliage to die back naturally. 
  • Finish the pruning of Roses earlier in the month. 
  • Cut Dogwoods, Willow, Cotinus, and Paulownia to the base to promote strong new growth. 
  • Start sowing hardy annuals outside including California Poppies, Nasturtiums, and Opium poppies Clean the Alpines when they start to bloom, remove the dead leaves, then mix with the grit to keep the leaves away from the humid soil.  
  • Keep Lillies and other summer flowering bulbs in pots and borders. 
  • Clean the borders, remove established and new growing weeds, then mix generously with garden manure. 
  • Sow native wildflower seeds in trays or modules, to prepare plants for your garden. 
  • Check tender new shoots for the Aphids, and remove the infestations before it gets out of hand. 
  • Continue dead-heading spring flowers and any remaining winter beds so they don’t set the seeds. 
  • Scatter the manure around flower beds and roses, shrubs, and hedges. 
  • Hardy annuals can be sown in pots or modules to provide color in the annual garden. In mild areas, you can sow directly out. Marking irregular-shaped seeds and broadcasting flows of different seeds look more natural.
  • Sweet Peas can be sown outdoors this month. Keep these in a sunny position, maybe on a shelf in the greenhouse that gets plenty of light. 
  • The middle of March month is a perfect time to plant herbaceous perennials, together with Geranium, Astrantia, and Oriental poppies.
  • Propagate dahlias more from the tuber. 
  • The perennials who are showing new shots from the crown can be propagated through Basal stem cuttings. 
  • Plant summer flowering bulbs. Prepare the soil first, ensuring that drainage is enough to prevent the bulbs from rotting. Anemone coronaria tuber sits in need of particularly well-drained soil.
  • Perennials like Delphinium and annuals can be grown to create a useful and beautiful display.
  • Continue to protect new growth from slugs and snails on Lilies, Delphiniums, Hostas, and any other infected plants.
  • The Aphids can grow faster during mild spells. Remove early diseases by hand to prevent the problem from getting out of hand. Protect sweet pea plants in particular, as they can find sweet peas viruses, spread by Aphids and other juice-sucking insects.
  • Keep an eye on the spot of Downy Mildew and black leaf on winter pansies. Take away any affected leaves and destroy badly affected plants.

Fruit gardening in March

  • To stimulate the new canes, cut the Raspberry canes of autumn to the ground, which will bear fruit in the autumn. Cut summer-flourishing Raspberry canes tips that have moved on from the top of their support, cut just above a bud.
  • Protect Apricots, Peaches, and Nectarines flowers from frost with screen or horticultural fleece.
  • Mulch fruit trees with well-rotted manure or garden manure. Be careful not to have a mound mulch around the trunk of the trees.
  • Cover the strawberries with a cloche to encourage them to take fruit before that. 
  • Mulch Rhubarb with a thick layer of well rotten compost to retain it healthy and reduce moisture loss through the soil. Be careful not to cover the crown, because it is where progress takes place.
  • Now plant Strawberries in banked rows in beds, or plant in containers.
  • Encourage the long, stalks of the Rhubarb to grow by covering your crowns with old buckets to emit any light.
  • Slowly remove the mulch from the Strawberry as the weather heats up.
  • Continue cutting apple trees. Burn or destroy all pruning to minimize the occurrence of insects or diseases.
  • Continue cutting grapes. Bleeding does not hurt the vines. Tie the vines to the trellis before the buds swell to prevent the injury of the bud and the damage to the crop.
  • When buds start to open, the Aphids start to come out on fruit trees.
  • Now apply dormant oil sprays. Choose a dry day when cold temperatures are not expected.
  • Spray Peach trees with fungicides to control the disease of peach leaf-curl.

Greenhouse care in March 

  • Take down bubble insulation in the greenhouse once temperatures rise, to go into more light. 
  • Sow the vibrant annual climbers like the Spanish Flag and the Black-eyed Susan. 
  • Buy good-value young bedding plants to grow on a larger size under glass, or sow your own in a hot propagator. 
  • Sow dwarf French beans in a large pot for an early internal crop in June. 
  • The plant produced Freesia bulbs in rich, loam-based compost pots for aromatic flowers indoors this summer.

  • Open greenhouse vents on sunny days to stop moisture build-up. 
  • Sow the Coleus on hot windows to enjoy your vibrant leaves in a tropical style display inside or outside the house.

  • Monitor plants at least every few days, to see if they need water. 
  • Open doors and vents at greenhouses to increase ventilation on hot, sunny days.
  • Vine weevil larvae can be a serious worm of containerized plants, and become active this month.

  • Brush the fallen manure and debris, and pick up dead leaves from the plants. This will help to stop the spread of pests and diseases.
  • Stem and root rot can affect young plants grown from seeds and cutting, especially those grown under glass.

General plant maintenance in March 

  • It is a good time to plan for the garden. Walk around the garden, looking for potential problems and things you want to prepare or change.
  • Re-pot the plants tied to the pot using fresh manure. Check the vine weevils while doing so.
  • Prune the roses that bloom again and again.
  • Cut any dogwood or willow back to the ground to encourage fresh new growth to showcase bright winter trunks next year.
  • Prepare flower beds ready to sow hardy annuals from the end of March to April.
  • add a mulch of well-rotted compost around the base of roses, fruit trees, and shrubs.
  • Pot houseplants and Ferns in a little large pot using fresh houseplant compost. Use this opportunity to clean the leaves of your houseplant and remove any dead or dying leaves.
  • Protect fruit tree flowers on cold nights using cover. Remove the cover during the day to give insects access to flowers.
  • If not already done, make sure garden tools and mowers are ready for the upcoming season and checked in good condition.
  • Check bird boxes and feeders for damage before fixing on a proper tree or wall. Make sure your boxes and feeders are located far away from cats.
  • Prepare a couple of raised beds for the early seed sowings. The cloches or portable polythene tunnels are great for the protection of young seedlings as well as trapping heat in the soil of your raised bed. Crops like Beetroot, Carrot, Parsnip, Radish, and spring onions are all the best choices.
  • Warm soil in your vegetable garden beds covering the surface with black sheeting. Black absorbs the rays of the sun and heats the soil below.

  • Go around the garden checking for the loss of frost. Cut back any affected stems.
  • Prepare the land to plant by digging the ground and then leveling it.
