Seasonal Jobs for a Healthy Garden in Early Spring

Reading the Season Before You Reach for the Secateurs

Early spring in Britain is a tease. One afternoon the sun has real warmth in it and the bees are out on the crocus; the next morning there is a crust of frost on the lawn and a bitter wind coming off the east. The temptation is to charge out with a list and a wheelbarrow, but the garden responds far better to a gentler approach. Work with the soil, not against it, and wait until the ground is dry enough that it crumbles rather than clags around your fork.

That said, early spring is one of the busiest and most rewarding windows in the gardening year. There is just enough time to tidy, feed and prepare before the great surge of growth arrives in April. The jobs below are the ones worth prioritising now.

Pruning Roses: The Year's Most Rewarding Cut

If you do only one job this month, prune your roses. In most of the UK, bush and shrub roses are best cut back in late February or early March, just as the buds begin to swell but before the leaves break. In colder northern gardens a fortnight later is fine; in mild coastal spots you can start a little earlier.

Use sharp, clean secateurs and take out the three Ds first: dead, damaged and diseased wood. Then open up the centre of the plant, removing any stems that rub or cross. Cut the remaining healthy stems back to around 15–30cm above ground for hybrid teas and floribundas, making each cut just above an outward-facing bud and sloping it away from the bud so water runs off cleanly. Climbing and rambling roses are treated differently: train the long stems horizontally and only tip back the side shoots.

Once pruned, a handful of rose fertiliser scattered around the root zone and lightly forked in will pay you back many times over in July.

Dividing Perennials While Growth Is Still Slow

Herbaceous perennials that flower from midsummer onwards can be lifted and divided now, while the soil is moist and the plants are only just showing new shoots. Clumps that have gone woody in the middle, or that flowered poorly last year, are prime candidates.

Lift the whole clump with a garden fork, working around it to avoid slicing through roots. Shake off loose soil, then split the clump with two forks placed back to back, or with a sharp spade for tougher crowns. Replant the healthiest outer sections at the same depth they were growing, spacing them generously, and water them in well.

• Good candidates: hardy geraniums, rudbeckia, asters, heleniums, daylilies and ornamental grasses.
• Leave alone: anything flowering before the end of May, such as primroses and pulmonarias, which are better divided in autumn.
• Replant divisions promptly and keep them watered for the first fortnight.

Any spare divisions make welcome gifts for neighbours, and the rejuvenated clumps will flower better for the disruption.

Sowing Hardy Annuals for a Long, Generous Summer

Hardy annuals are the cheapest colour in the garden, and early spring is the moment to sow them direct. The signal to start is soil temperature rather than the calendar: once the top few centimetres have warmed to around 7°C and the surface has dried enough to rake to a fine tilth, you can sow with confidence.

Prepare the ground by clearing weeds and raking to a crumbly finish. Sow thinly in shallow drills or broadcast over the surface, then cover lightly with soil and water gently. If a cold snap is forecast, cloches or a layer of fleece will protect the seedlings without fuss.

• Reliable choices: cornflower, calendula, nigella, poppies, godetia and candytuft.
• Sweet peas sown now will scramble away strongly once the weather settles.
• Thin seedlings to 15–20cm apart once they have two true leaves — crowded plants sulk and mildew.

Succession sowing every three or four weeks until early summer keeps the display going rather than exhausting it in one glorious fortnight.

Checking Supports Before the Growth Arrives

It is far easier to put stakes in now than to wrestle them into a collapsing border in June. Walk the garden after a windy night and look at what has moved.

• Firm back any loosened tree ties and check that they are not cutting into bark.
• Replace broken stakes and renew frayed twine on climbers and wall shrubs.
• Push pea sticks or hazel supports into the ground around tall perennials before they need them.
• Check netting over fruit cages and brassica beds, and repair any gaps.
• Inspect trellis, fence posts and greenhouse glazing for winter damage.

Getting the skeleton of the garden right now means the soft new growth has something to lean on when it comes.

Mulching Beds to Lock In Spring Moisture

A generous mulch is the single best investment you can make in a border. Spread well-rotted manure, garden compost or leafmould 5–7cm deep over the soil surface, working it around the crowns of plants but keeping it clear of stems and trunks, where it can cause rot.

Mulch onto damp soil, ideally just after rain, and never onto dry ground — water thoroughly first if necessary. The benefits are cumulative: moisture is held through the drier months, weed seeds are smothered, worms and soil life are fed, and the border looks instantly cared for. A light feed for hungry plants such as roses, clematis and vegetables can be forked in beforehand.

Above all, resist the urge to tidy too fiercely. Leave the last of the seedheads for the birds, tread lightly on wet borders, and let the season unfold at its own pace. The garden will thank you.
