Gardening In April
It’s officially spring and officially a great time to tend to your garden! We’ve put together some ideas for planting, sowing, tending, mowing and more during April to make your garden look its best. Green fingers at the ready!
If you haven’t completed your first mow since winter yet, do this now and set a high height on your lawn mower for the first trim. If your grass needs a top-up, sow lawn seed and keep the soil moist while it’s bedding in. Alternatively, lay new turf and also keep this moist. Consider using a high-nitrogen fertiliser and lawn weedkiller if necessary. Mow your lawn more regularly and trim the edges.
Maintaining Plants, Trees and Shrubs
Keep weeding your garden, including finding the roots of any bindweed and treating it with weedkiller. Deadhead spring bulbs and bedding, and protecting new shoots of vulnerable plants from slugs and snails. To look after your roses and protect them from blackspot, spray new leaves with fungicide. Check them for aphids, too.
Feed trees and shrubs with fertiliser. Prune hydrangeas, tie in climbing roses and lift and divide and replant border perennials and primroses. If the soil isn’t frozen or waterlogged, you can also move evergreen trees and shrubs if you need to. Loosen any tight tree stakes and ties to give the trunks room to expand.
Cut back dead foliage on grass plants to allow for new growth, and deadhead daffodils and tulips while leaving the foliage intact. Add mulch to the soil around perennials and biennial plants and shrubs.
Planting New Plants and Seeds
Now is the time to sow hardy annuals such as marigolds in your borders. For some instant colour, plant primulas and polyanthus in pots and in borders. Potted pineapple lily bulbs will also make beautiful summer flowers. It’s also the right time to sow sunflower seeds, plant new evergreen trees and shrubs, and add water lilies and other aquatic plants to ponds.
Planting Fruit and Vegetables
Prepare soil for planting and cover it with black plastic to keep it warm and dry while you get it ready. Now is a good time to plant tomatoes and cucumbers undercover, as well as asparagus crowns, onions, shallots, garlic and maincrop potatoes. If you’d like some homegrown salad, consider sowing rocket, lettuce and rainbow chard, as well as herbs such as chives, coriander, dill and chervil. Radishes are fast-growing and can fill in any gaps in your vegetable plot. You can also sow tomatoes, courgettes and chillies in pots ready to plant in June.
Make supports for pea and bean plants and mulch for fruit trees. On cold nights, protect fruit blossoms from late frosts by covering them with horticultural fleece. Rotavate your vegetable garden.
Ventilate your greenhouse on warm days, when they finally arrive! Your potted courgettes and tomatoes should be placed in your greenhouse if you have one. Sweet peas, kale and mustard can also be sown and kept in the greenhouse. If you don’t have guttering on your greenhouse, consider adding some and installing a water butt to make use of rainwater. Clean your greenhouse to let in as much light as possible, and give more water to houseplants.
Keep putting out food for birds and top up birdbaths or water features. Encourage creatures such as hedgehogs and frogs into your garden to keep pests at bay. You can do this by providing them with water to drink, undergrowth to hide in and gaps for them to wander between your garden and your neighbour’s.
If you need any new tools or garden machinery to begin any of these jobs, you’re in the right place. Take a look at our lawn mowers, multi-tools, greenhouses, rotavators and tillers, ladders, spreaders, grass trimmers and hand tools.
