Expert Gardening Tips & Advice for April 2026
March has finally given way to the longer, warmer days that every gardener waits for. After yet another unpredictable winter with its familiar mix of storms, sudden cold snaps and the occasional glimpse of sunshine, April arrives like a welcome old friend. The garden is waking up with real purpose now — blossom is on the trees, bulbs are reaching their peak, and the soil is at last beginning to warm beneath our feet. This is one of the most rewarding months in the gardening calendar, and there is a great deal to get on with. Below are our recommendations for what you should be doing in your garden this April.
🌿 Lawn Care
April is the month when lawns really come back into their own and need proper attention for the first time since autumn. Begin with a light raking to remove any moss and the thatch that has built up over winter, then mow with the blades set high — around 4cm is ideal. Cutting too low too soon places stress on the grass and creates opportunities for weeds and moss to take hold again. Once mowing is underway, apply a spring lawn feed with a high nitrogen content to encourage strong, lush growth. For areas that have become compacted over winter, use a garden fork or hollow-tine aerator to open up the soil and improve drainage. April is also an excellent time to sow seed or lay turf for any new areas of lawn you have been planning.
🌸 Beds, Borders & Planting
As the garden bursts into life, now is the moment to get your beds and borders in order for the season ahead. Clear away any remaining winter debris and weeds, then fork over the surface of the soil, taking care not to damage the shoots of newly emerging bulbs and perennials. Apply a layer of mulch — well-rotted garden compost or farmyard manure works wonderfully — around established shrubs, roses and perennials. This helps suppress weeds, retain moisture as the drier months approach, and feeds the soil slowly throughout the season. Keep the mulch away from plant stems to avoid any risk of rot.
As roses, shrubs and trees begin to put on fresh new growth, scatter a slow-release general purpose fertiliser around their base and rake it in gently before laying the mulch. Spring bulbs such as daffodils and tulips will be in full glory now — deadhead the spent flowers but always leave the foliage to die down naturally. It is tempting to tidy it away, but the leaves are busy feeding the bulb for next year's display.
✂️ Shrubs, Climbers & Pruning
- Hard prune shrubby dogwoods (Cornus sibirica, C. alba) now to encourage the brightly coloured shoots that will light up next winter's garden.
- Trim lavender lightly to tidy the plant, but take care never to cut back into old wood — it will not regenerate from it.
- Pinch out the growing tips of fuchsia and sweet pea seedlings to encourage bushy, well-branched plants with more flowers.
- Give trees, shrubs and climbers in containers a boost by knocking them from their pots, removing a little old compost from the base and sides of the rootball, and refreshing with fresh compost. Top-dress with around 2.5cm of new compost and follow with a slow-release fertiliser.
- Tie in the new growth of climbing roses and wall shrubs before it becomes too long and difficult to manage.
🥕 The Vegetable Garden
April is one of the most exciting months for the kitchen garden, with sowings gathering pace and early crops beginning to show. Get vegetable beds ready by clearing them of weeds and digging in garden compost or well-rotted farmyard manure to improve soil structure and moisture retention. The soil has warmed sufficiently in most parts of the UK for a good range of direct outdoor sowings.
Sow outdoors directly into the ground: broad beans, carrots, beetroot, parsnips, spinach, lettuce, spring onions, radishes and salad leaves. For a continuous supply of salad throughout summer, sow in short rows every two weeks rather than all at once. This approach prevents a glut and keeps the harvest coming.
Indoors or under glass, continue to sow: tomatoes, cucumbers, courgettes, pumpkins, squash, runner beans and French beans, as well as nasturtiums, sunflowers and dahlias. Do not be tempted to plant tender vegetables such as tomatoes and courgettes outside yet — the risk of frost in most parts of the UK remains until mid-May. Grow them on in your greenhouse or on a warm, bright windowsill and wait until late May to plant out.
If you have not yet done so, chit the remaining seed potatoes and plant early varieties towards the end of the month if conditions allow. Keep fleece handy to protect the emerging shoots from any late frosts.
🏡 Greenhouse & Under Cover
The greenhouse will be a busy and rewarding place throughout April. Keep a close eye on ventilation as temperatures can rise surprisingly quickly on sunny days — open vents and doors during the warmest part of the day, and close them again before evening. Damping down the greenhouse floor on hot days raises humidity and can help deter red spider mite, which thrives in hot, dry conditions.
- Pot on tomatoes, peppers and aubergines into their final containers or growing bags as they develop.
- Begin hardening off young plants raised from seed that are destined for outdoor growing — place them in a cold frame or sheltered spot outside during the day and bring them under cover at night.
- Citrus plants kept under glass through winter can be given a top-dressing of fresh compost and a high-nitrogen feed to encourage a flush of healthy new growth.
- Check all plants carefully for signs of aphids and other pests, which can build up rapidly in the warmth of a greenhouse at this time of year.
🐝 Wildlife & Eco-Friendly Gardening
April is a wonderful month to consider the wildlife that shares your garden. Bees, butterflies and other pollinators emerge in increasing numbers as the weather warms, and they will be grateful for early sources of nectar. Flowering currants, pulmonarias, aubrieta and wallflowers are all particularly valuable at this time of year. If you have space, consider sowing a patch of hardy annuals such as poppies, cornflower and nigella — these are easy from seed and provide a long season of colour and pollinator habitat.
Now is also a good time to set up or clean out nestboxes if you have not already done so — many birds are in the process of choosing a nesting site this month. Avoid using pesticides or weedkillers wherever possible; the RHS reports that 80% of UK gardeners have now moved away from chemical treatments, and a more relaxed attitude towards weeds and minor pest damage benefits the whole garden ecosystem in the long run.
💧 Ponds & Water Features
Ponds come alive in April. Frogspawn and tadpoles will be visible in many garden ponds now, so be careful if carrying out any maintenance. Remove any blanket weed that has appeared over winter, and thin out oxygenating plants if they have become too dense. As water temperatures rise, pond plants such as water lilies will begin to grow strongly — divide and replant overcrowded specimens if they have not been split in the last few years. Ensure there is always a gently sloping side or a plank leading from the water to help any creatures that may fall in to escape safely.
📋 General April Garden Checklist
- Use a hoe regularly to keep weeds under control in beds and borders — little and often is far less work than tackling them when established.
- Check hosepipes, irrigation equipment and water butts are in good order ahead of the drier months.
- Keep a watchful eye on weather forecasts and have horticultural fleece ready to protect tender plants and early potato shoots from any late frosts — April can be deceptive, with warm days followed by cold nights.
- Feed established container plants with a liquid fertiliser as they resume active growth.
- Stake tall perennials and gladiolus corms early, before the growth gets ahead of you and stems become damaged in wind.
- Continue to keep on top of slugs and snails, which will be active on damp evenings — physical barriers, wildlife-friendly pellets or a torch patrol in the evening are all effective methods.
April is one of those months when the garden gives back generously for every hour invested in it. The sense of optimism that comes with spring is one of gardening's great gifts — enjoy every moment of it. Whatever your project this month, the team here at Heritage Gardens wishes you a wonderful season ahead.
