What To Do in the Garden in March

Spring arrives in the middle of this month, bringing increasingly sunnier, brighter days which can only mean one thing, it’s time to dust off your gardening tools and get busy with this month’s gardening jobs. It’s not only time to spring clean indoors, but your garden as well as your outdoor space will need a general tidy. Some of this months top jobs include cutting back winter shrubs and sowing this year’s seed. 

As the temperatures warm up your garden will begin to come alive after its winter break. Take a look at all of the jobs to do in your garden throughout March.

What To Do in the Garden in March

Plants and Flowers:

  • Deadhead any spring bulbs that flowered earlier in the year but leave the foliage to die back naturally.
  • Begin reducing the number of times that you prune your Roses, eventually stopping to avoid cutting new growth.
  • Hardy annuals can begin to be planted outside 
  • Perennials can also begin to be planted in greenhouses and propagators.
  • Plant summer flowering bulbs such as Lilies in borders and pots 
  • Shrubs including Rhododendrons and Camellia will appreciate a high quality fertiliser to help with soil quality and give a boost to their growth
  • Tidy bedding and border plants, removing any remaining debris and mulch with a high quality compost. 
  • A general purpose fertiliser should be spread evenly over flower beds, around roses, shrubs and hedges. Once your soil is workable, dig a 5 cm layer of compost or fertiliser such as fish, blood and bone into your beds to prepare it for the growing season ahead.  If you need help finding the right fertiliser for your soil type and plants.
  • If any of the plants you are growing this year require support, begin adding them to the young plants as this can be tricky to do as the plant matures.
  • Cut back dead foliage from perennials and ornamental grasses to allow for new growth. 
  • If you have purchased Dahlia’s as tubers, do not plant for at least 6 weeks after the last frost as they are prone to frost damage.

Lawn Care:

  • As your lawn begins to grow back, begin to mow. Try to choose a dry day and set your blades higher than usual.
  • Recut your lawn edges and install edging to make ongoing maintenance quicker and easier.
  • You can also begin to weed and add fertiliser, read more about how to look after your lawn and tips here.

In the fruit and vegetable patch:

  • Plant both onions and shallots early in the season. Parsnips should also be planted as soon as the ground begins to warm up as they need a longer growing season. You can find out more on how to grow both onions and parsnips in our handy how to guides. 
  • Feed Cabbages with nitrogen rich fertilisers to help with growth.
  • Hoe your vegetable patch regularly to stop weed growth as the temperatures rise.
  • Cover your prepared soil with sheets of black plastic to keep it drier and warmer in preparation for planting, if you are yet to sow. 
  • Fruit trees should be mulched with high quality manure, garden compost or fertiliser. 
  • More delicate seeds such as Celeriac, Celery, Lettuce and Parsley can be started indoors as they will germinate better and then be transplanted outside as the weather gets consistently warmer.

Pests and Weeds:

  • Remove established and newly germinating weeds to make your jobs easier as the temperature rises.
  • Check new growth on plants for signs of aphids and remove before plants become infested
  • Look for slug and snail damage as the weather is still damp and where necessary apply pesticides.

Watering Tips:

  • Still give your garden and plants regular watering, but this will depend on the size, species and stage of growth your plants are at. 
  • Try to water in the mornings as the sun will heat the soil and encourage absorption. Watering in the evening can make the soil stay damp, encouraging diseases and pests.


  • Begin to think about making the most of the spring rains with well positioned water butts. 
  • Select and buy annual bedding and vegetable plants, ready for planting later in the season.
  • Organise and sort your seeds by growing date to make sure you don’t miss any of the species you would like to grow. Make a note of when these need to be planted on your calendar.

Something for the little ones:

Keep putting food out in the garden for the birds, as the breeding season gets underway they will need more food for their young. Read about top tips for encouraging wildlife to your garden here.
