Spring has officially arrived, and with it comes a burst of energy for your garden. April is an exciting month in the UK garden, as it marks the perfect time to prepare your outdoor space for the coming summer.
Whether you’re an experienced gardener or just getting started, here are some essential gardening tasks you can tackle this month to ensure a beautiful garden for the rest of the year.
Prepare your soil for planting
Now that the weather is warming up, it’s the perfect time to prepare your soil. Start by removing any weeds that have sprouted during the winter. You can do this by hand or with a hoe, ensuring you’re not disturbing the soil too much. Next, loosen the soil with a fork or spade to allow air and water to reach the roots of your plants.
If you have heavy clay soil, add compost or well-rotted manure to improve drainage. For lighter, sandy soils, add organic matter to improve fertility. This will give your plants the best chance to thrive come planting season.
Plant early vegetables and herbs
April is the perfect time to get a head start on your vegetable garden. In mild areas, you can begin sowing seeds for crops like lettuce, spinach, carrots, radishes, and peas directly into the soil. If you have a greenhouse or cloche, consider starting early crops such as tomatoes, peppers, and cucumbers to get them ready for planting out later in the season.
Herbs such as basil, chives, mint, and parsley can also be sown now. These hardy plants are perfect for growing on windowsills, pots, or in raised beds.
Prune spring-flowering shrubs
April is a great time to prune early spring-flowering shrubs like forsythia, camellia, and lilac after they’ve finished flowering. This helps keep them tidy and encourages healthy growth for next season. Be sure to cut back dead or damaged stems and trim back any overly large branches to maintain a good shape.
For roses, if you haven’t already done so in March, now is a great time to cut back dead or diseased stems and encourage new growth.
Mulch your garden beds
To retain moisture, suppress weeds, and enrich your soil, it’s time to mulch! Spread a layer of organic mulch, such as wood chips, bark, or compost, around your plants. This is especially beneficial during drier months when water retention becomes more critical.
Be sure not to mulch too thickly or directly over the plant crowns, as this can cause them to rot. A few inches will suffice, providing protection while still allowing air circulation to the roots.
April is a fantastic time to start planting your summer bulbs like dahlias, lilies, gladiolus, and begonias. These vibrant flowers will add color and texture to your garden in the summer months. Make sure to plant them in well-drained soil and follow specific depth guidelines for each type of bulb and use the right kind of compost
Plant summer bulbs and perennials
This is also an ideal time to plant perennial flowers that will provide long-lasting beauty year after year. Choose varieties suited to your garden’s conditions—whether sunny, shady, dry, or damp—to make the most of your space.
Tidy your lawn
Now that the worst of the cold weather is behind us, your lawn will begin to wake up from its winter dormancy. Start by giving it a good mow to remove any debris and give the grass a fresh start. Make sure not to mow too short – keeping the grass a little longer during early spring helps protect the roots from frost and encourages healthy growth.
If you have bare patches, now is the time to reseed your lawn. April is also a good time to apply a slow-release fertiliser to give your lawn a nutrient boost.
Start feeding your plants
As the days grow longer and warmer, plants begin to come out of dormancy and need nourishment. Start feeding your established plants, such as shrubs, roses, and fruit trees, with a balanced fertiliser to support their growth.
For your vegetables, it’s helpful to feed them with a general-purpose liquid fertiliser once they’re established in the ground. This helps them develop strong roots and encourage productive growth.
Start thinking about wildlife
Spring is a great time to plan for the wildlife in your garden. Consider putting up bird boxes, bat boxes, or creating a small pond to attract wildlife to your outdoor space. By including a range of plants and structures, you can support local biodiversity and have the opportunity to observe fascinating wildlife throughout the year.
Check greenhouse plants
If you have a greenhouse, check on the plants that may have overwintered there. Make sure there’s enough ventilation to prevent humidity buildup, which can lead to mold or pests. Now is also the time to sow your seeds for summer crops and to get your greenhouse plants acclimatised to outdoor conditions by hardening them off before transplanting them outside later in the season.
Get ready for pest control
As your garden begins to bloom, it’s important to stay on top of pest control. Aphids, slugs, and snails can cause havoc in your garden during spring. Keep an eye out for pests and remove them by hand or use organic methods like neem oil or a garlic and soap solution. You can also introduce beneficial insects like ladybirds, which naturally control aphid populations. We’ve written a blog on dealing with garden pests which might be helpful.
