Gardening in March
Things to do this month
Don’t overdo it this month. Take your time and concentrate on the most important jobs and the ones you enjoy doing most.
Sow seeds of all your favourite annual bedding plants for a summer of wonderful colour.
If you don’t have much success with seeds, it’s better to buy plug plants and seedlings for growing on.
Buy pansy, primrose and polyanthus plants plus potted spring bulbs for some instant colour.
If you spend a lot of time watering in summer, consider installing an automatic drip watering system.

Sow tomatoes, sweet and chilli peppers, cucumbers and aubergines indoors with warmth.
Mulch the soil around trees and shrubs with a 5-7.5cm (2-3in) thick mulch.
Prune summer- and autumn-flowering clematis. Leave spring-flowering clematis until after they’ve finished flowering.
Prune bush - hybrid tea and floribunda - roses.
Prune summer-flowering deciduous shrubs, such as Buddleja, Caryopteris, lavender, Lavatera and Perovskia.
Remove suckers from plants that are grafted onto a rootstock as soon as you see them.

Put out suitable food for hedgehogs as they emerge from their winter hibernation.
Feed all your garden plants with a suitable plant food as they come into growth.
Stock up your borders with new shrubs and herbaceous perennials.
Buy summer-flowering bulbs, such as begonias, dahlias, gladioli and lilies.
Put plant supports in place around herbaceous perennials that start into growth early in the year.
Deadhead daffodils and other bulbs when the flowers fade and give them a liquid feed.
Tie in the shoots of climbers as they grow, spreading them out evenly over their support.

Clean secateurs blades after use to help prevent spreading diseases between plants.
Take stem cuttings of half-hardy perennials and patio plants, such as fuchsias and pelargoniums.
Make sure you grow plants that are beneficial to butterflies, bees and other garden-friendly insects.
Sow hardy annual seeds outside for an inexpensive way to produce lots of flowers.
Start feeding lawns with a granular lawn food.
Rake out dead grass and other debris (thatch) with a spring-tine rake to improve conditions for grass growth.
Re-cut lawn edges with a half moon edging iron to give them a crisp and even look.
Treat weeds and moss growing in the lawn with a product suitable for lawns.

Repair damaged and bare areas with fresh grass seed.
Overseeding the lawn with new grass seed will help thicken it up and produce a darker green colour.
