What to do in the garden in April
April is when the garden shifts up a gear. Soil temperatures rise, rainfall supports strong root growth and longer days drive rapid top growth. Lawns respond quickly, borders fill out and weeds move just as fast. It is a productive month, but timing and consistency are key.
Expect changeable conditions. Warm sunshine can be followed by sharp winds or late frosts. Keep fleece on hand for tender plants and avoid planting out anything vulnerable too early. Growth is accelerating, so regular maintenance now prevents problems later.
If you planted spring bulbs in autumn, many will be at their peak or just finishing. Deadhead spent blooms promptly but leave the foliage intact. The leaves are essential for photosynthesis, allowing the bulb to store energy for next year’s display.
Lawns will need more frequent mowing as growth increases. Start with blades set high and gradually lower over several cuts. Never remove too much in one go, as this weakens the turf.
Ornamental garden jobs in April
• Remove faded flowers from spring bulbs, leaving foliage to die back naturally.
• Keep borders weed free while growth is manageable.
• Continue mulching beds and borders to retain moisture and suppress weeds.
• Lightly trim weak or straggly growth on herbs such as sage and rosemary in mild weather.
• Cut back penstemons to new growth once risk of hard frost has passed.
• Check evergreens for frost damage and prune lightly if required.
• Monitor for aphids and treat early to prevent infestations.
• Direct sow sweet peas for later flowering displays.
• Prune early flowering shrubs such as forsythia once flowering has finished.
• Feed roses with a balanced fertiliser to support strong new growth.
• Plant or reposition evergreen trees and shrubs if conditions are suitable.
• Trim away any remaining frost damaged foliage.
• Plant summer flowering bulbs, corms and tubers including dahlias, gladioli and cannas.
• Apply a combined lawn feed to support growth while addressing moss and weeds.
• Pot up hydrangea cuttings and protect from cold nights.
Vegetable garden jobs in April
• Continue planting potatoes and finish onion sets by mid month.
• Direct sow beetroot, carrots, lettuce, radish, turnip, peas, spinach and parsnips into prepared soil.
• Prune young stone fruit trees such as cherries and plums as leaf buds open.
• Sow tomatoes under protection for planting out later once frost risk has passed.
