It has been a slog, hasn’t it? I hardly dare to believe Spring is here – and the cold weather may yet come back to bite us, but at least it is lighter, cheerier and people are beginning to smile in the street when they meet each other!
A few years ago I helped with a garden that had two long borders at the entrance. Once upon a time the planting was quite bitty and lacking in cohesion. Now, with a dark Yew hedge backing these borders, all the colours, especially the Spring colours, shout out in glorious yellows and pales greens that the good times are almost here. You will get far more out of your garden if you think about how to show off the plants to their best advantage.
Daffodils do a wonderful job at this: if you are going to plant them, try to establish “drifts” rather than straight lines. Densely planted they will make far more of an impact. There have never been a wider range of Hellebores to choose from, but the whites and limey yellows will lift any border. Forsythia will do what they do best and Mahonia will add scent with their yellows.
Many Euphorbias will give strong shapes as well as yellows, especially those from around and near the Mediterranean such as characias wulfenii and ‘Humpty Dumpty’, it’s diminutive relative.
Fortunately, we don’t have to go to the Mediterranean for them these days – which makes time for this month’s tasks!
• Keep planting bare-root trees and shrubs but wait until the end of the month before you plant or move evergreens.
• Cut back dogwood and willow shrubs with the vibrant stems if you want them to produce strong colours next winter. Taking them down as far as 100mm (4 inches) from the ground is fine. (The ‘Winter Flame’ and ‘Anny’s Winter Orange’ varieties should be left for a few years until they are established and then only lightly pruned). You can leave this task till late in the month or even next month if you are enjoying the stem colours.
• When the worst of the frosts are over, divide and replant clumps of herbaceous plants that have become too dense for their own good.
• In heavy soil and cold areas, march is the best month for planting roses. Prune bush roses by about a third of their height.
• In preparation for the new growth and flowering in the summer, prune Buddleja, Caryopteris, Ceratostigma, Hydrangea paniculata, Leycesteria, Lavatera, Perovskia and hardy Fuchsia. Look up how far back they should be pruned: this will vary according to what you are trying to achieve and the location of the plant.
• Mow lawns but on a high cut setting and not when frosts are about to appear as it will damage the lawn.
• Plant and divide snowdrops and winter aconites.
• Plant summer flowering bulbs and sow some seeds such as sweet peas.
• Cut back ornamental grasses, even if they do not look unruly, as this will make way for new growth. Rake out the old growth from gasses such as Stipa tenuissima.
If your garden feels a bit stale or predictable after a long winter, then why not visit one of the great gardens near you open to the public? It’s hard to come away from them without feeling lifted up.
