Gardening Tips For March

March is a month of contrasts - false starts and occasional ferocious blips in the weather BUT....the flowering of early bulbs and the green haze forming on shrubs and hedges are a sure sign that Spring is almost upon us and that the real work of gardening and growing can soon begin in earnest.

Plant Climbing Roses 

This is a good time to plant any bare root roses, as March signals the ends of the bare root season so get yours in now and look forward to a stunning display.

 To plant roses to grow up a structure or an arch:

  • Dig a hole twice the width of the root system and the depth of a spade.
  • Include a generous amount of well rotted compost or manure to get the plant off to a really good start. 
  • Tidy up existing roses by removing dead or diseased stems.
  • Use climbing wire, twine or twist ties to tie any stray shoots to the structure or arch.

Plant Hedges & Prune Shrubs

By planting hedges now, they will establish and make good growth in their first season.

Pruning of any established hedging should be carried out around now, before birds start to nest. After this, maintenance trimming can be continued - usually once a year for informal hedges and twice a year for formal hedges. 

Cut back the stems of Dogwoods and Willows hard to ensure bright stem colour for next winter.

You can prune shrubs at any time of year if it’s necessary - for example, to remove broken branches or diseased wood, or to remove growth that is obstructing a walkway - but on an in-leaf shrub it’s harder to see what needs to be cut so now is a good time to get the job done.

March is a good time to prune shrubs as they have lost their leaves and become dormant - again without the leaves you can easily see the branching structure of the shrub and can spot where to prune.

Sow Sweet Peas

For best results sow Sweet Peas under cover in late October/November or at the beginning of March as temperatures and light levels are optimum - seeds sown now will still create a glorious fragrant show this Summer.

To pinch sweet pea plants, wait until they are 10 cm to 20.5 cm high then take the growing tip between your forefinger and thumbnail and snip the growing tip off - this encourages bushy growth and sturdy plants ready to plant out when the temperature rises.

Sort through your seed collection and order something new – the warmth of the greenhouse is an ideal place to shelter from March winds and plant your planting with a cup of tea.

Maintain Your Lawn 

Keep off your lawn in frosty weather but it will benefit from raking, feeding and weed treatment if the weather is fine. Start with with the mower blades set on their highest setting, and only decrease the height when the season is well underway.

There is something so uplifting about the first cut of the season and it will invigorate the grass and transform the look of your garden!

Divide Congested Clumps

Hostas are a perennial favorite among gardeners -their lush foliage and easy care make them ideal for a low maintenance garden, especially in a planter where they can be more easily protected from slugs and snails.

Before their leaves start to grow, divide large clumps of hostas - dig the clump up, then use a spade to slice your clump into several sections, replanting them at their original level.


Aconites and Snowdrops are a welcome sign that Spring is almost here. Bold and weather-proof, they catch what little sun there is and light up the darkest of corners.

Winter Aconites and Snowdrops both transplant best ‘in the green' so now is the time to divide any congested clumps into either doorstep planters or plant them around to naturalise the landscape with drifts of them next year. Dot them amongst sleeping border perennials as well as under trees in the long grass. 

Fruit & Vegetables To Sow

Try to avoid digging in wet weather, but if gardening on wet soil, work from a plank of wood or an EasyPath, to avoid treading on the bed and compacting the soil.

Rhubarb

Rhubarb and Chicory can be forced in late winter by covering with a forcing jar or bucket, or by placing potted plants in the dark, to produce earlier, paler, sweeter growth, but don't be tempted to force for too long as you may weaken the plant. They can be ready to harvest as early as March, several weeks before plants left to grow normally.

Peas & Beans

Peas can be sown now into lengths of guttering or Rootrainers, ready to transplant into position in the garden later this month - this will give an early crop and are ideal for succession sowing.

If there’s one crop that sums up the pleasure of growing your own, is the humble bean. Most beans are very quick growing and, once they get going, you can expect week after week of tender, delicious tasting pods.

Consider what plant support you are going to use for your peas and beans this year. Using purpose-built  Pea & Bean Hoops with Jute Netting or a Deco Growing Frame is the easiest way to make the right support for the peas and climbing beans to grow their way up and can be used year after year. They are a great way to add height to a Kitchen Garden and make an attractive feature.

Potatoes

Freshly dug new potatoes are one of the greatest joys of a kitchen garden – plant some of your earlies out at the end of the month - a potato patio planter placed in a sheltered and sunny spot can help encourage an early crop.

Problems To Look Out For

Protect all your early seed sowings from slugs and snails by using a slug and snail catcher and place netting on top of brassicas to protect these from pigeons and other birds. 

Weeds can be controlled whenever they are troublesome, which is usually in the Spring and Summer months but it is a good idea to put weed barriers in place in late winter or early spring, as they work better as a preventative measure. Keep on top off weed control with hand-weeding with a fork or a SpeedWeed.

Until 1752, March 25th marked the first day of the year and whilst our calendars now tell us otherwise, it is still March that heralds the beginning of the ‘Gardening Year’ for many of us - Happy New Gardening Year!
