April Notes From the Potting Shed
with Gardening Expert Chris Milborne
April is definitely one of the most exciting months in the garden, one of my favourites. The longer days, warmer weather and increasing sunlight make it a season full of growth. You notice more changes now than at any time of the year – leaf buds on trees and shrubs, and as the month progresses the fresh leaves unfurl, and by the end of the month there is a canopy of fresh leaves.
This year I have seen more wrens about, with their distinctive birdsong in hedgerows and sheltering in shrubs, and more ladybirds – perhaps a sign of the milder winter weather. Flower beds and borders that a week or two ago were just empty brown soil are now full of fresh growth of herbaceous perennials, the ruby stems of young paeony shoots, and this month is all about colour. Magnolias in flower have looked superb, ornamental cherry blossom has been brilliant, and as the early daffodils and crocus fade, a fantastic array of many-coloured tulips takes over, along with sweetly scented wallflowers and early Clematis montana.
It is perhaps one of the busiest months for gardening – sowing for summer vegetables and flowers, pricking out and potting on, taking cuttings, planting out and planning for the summer months ahead. Every garden, whether large or small, should have a tree. Apples, pears, plums and cherries not only provide height and structure, but also glorious blossom and fruit, and can easily be grown in small gardens or even in containers. Crab apples are also brilliant, with long-lasting blossom, autumn colour and fruit enjoyed by overwintering birds.
In smaller or shadier gardens, Japanese acers cannot be beaten, with green, orange, purplish or reddish leaves unfurling at this time. They make excellent companions for camellias, rhododendrons and azaleas. I also plant hostas, ferns, epimediums, pulmonarias and pieris, followed by Hydrangea ‘Annabelle’ to extend the flowering season.
This month is also a great time to plant roses, bringing abundant flowers and fragrance throughout the summer. Put in plant supports around herbaceous plants now, before they grow too large. As the soil warms and everything grows at pace, feed all plants – especially after winter rains have leached goodness from the soil – and mulch with organic matter to retain moisture.
Plant summer flowering bulbs such as lilies and gladioli, and plant dormant dahlia tubers in rich soil in a sunny spot. Prepare the lawn by removing moss and thatch, repairing edges and bare patches, and feeding to encourage strong growth.
Grow Your Own
It’s a great time to grow, pick and eat something you have grown yourself. Many vegetables, especially salad leaves, can be grown in tubs and containers. Sow small amounts regularly for succession – lettuce, rocket, radishes and coriander.
Plant herbs according to conditions: rosemary, sage, thyme and oregano in full sun and well-drained soil; chives, mint, parsley and dill in part shade and moist soil. When potting on, avoid overwatering young plants.
Sow under cover runner beans, French beans, courgettes and squashes for planting out in May. Sow directly outside peas, beetroot, radish, spinach, carrots and more. Plant potatoes now. Strawberries grow well in beds, pots or baskets – keep watered and feed regularly.
April – enjoy every minute outdoors and the beauty of spring. It cannot be beaten.
