Tidy borders by removing dead leaves and debris to reduce pests and disease
Weed regularly, as warmer soil encourages rapid growth
Mow the lawn weekly, keeping blades higher at the start of the season

What to Plant in April:

April offers excellent planting conditions, with warming soil and longer daylight hours supporting strong growth.

Vegetables to Plant in April

April is an ideal time to sow a wide range of vegetables, with warming soil and longer days creating excellent growing conditions.

Plant potatoes: Second early and main crop potatoes can still be planted if you missed March. Choose a sunny, well-drained spot for best results.
Start tender vegetables indoors: Sow courgettes, pumpkins, squash, and runner beans indoors now to give them a strong start before transplanting outdoors in May.
Sow salad crops outdoors: Lettuce, radishes, spinach, and peas can be sown directly into the ground. These cool-season crops grow quickly in spring conditions.
Grow spinach: Sow in rich, moist soil for fast results. Spinach is ideal for succession sowing, with leaves ready to harvest in as little as 4–6 weeks.
Grow beetroot from seed: Sow directly into well-prepared soil. You can expect baby beetroot in 6–8 weeks, with full-size roots ready in around 10–12 weeks.
Start tomatoes indoors: Sow seeds in a warm, bright spot or propagator. Once seedlings develop true leaves, pot them on. If space is limited, growing tomatoes in pots is a practical option. Place them in a sunny, sheltered position and provide support as they grow.

These vegetables are reliable, easy to grow, and perfect for getting your garden off to a productive start in April. For more guidance, check out our blog on how to grow vegetables from seeds.

Flowers to Plant in April

April is a great time to start planting flowers, with milder temperatures and improving soil conditions creating the perfect environment for growth. Whether you are new to gardening or have years of experience, there are plenty of options to bring colour into your garden.

Marigolds, cosmos, and zinnias are reliable hardy annuals that can be started indoors or sown directly outdoors in milder areas. They are easy to grow and provide bright, long-lasting displays.
Sunflowers are another simple and rewarding choice. Sow seeds directly into well-drained soil in a sunny position, where they will thrive and grow quickly.
Petunias and lobelia are ideal for containers, window boxes, and hanging baskets. You can start them indoors or choose young plants that are ready to be planted out.
April is also the right time to plant summer bulbs such as dahlias and begonias, which will produce vibrant colour throughout the summer months.

For longer term planting, add perennials like echinacea, coreopsis, and salvia. These plants return each year and help build structure and consistency in your garden.

To create a more visually appealing space, combine a mix of colours, heights, and textures. Whether you are designing a cottage style garden or planting up a balcony, April offers the perfect opportunity to get started.

Pruning in April: What You Can Still Cut Back

If you missed some March pruning, April gives you a last chance to catch up before plants move into full growth mode:

Pruning Spring Flower Shrubs

Once shrubs like forsythia, kerria, and flowering currant have finished blooming, prune to maintain shape and encourage next year’s flowers.
Lavender: Avoid pruning lavender too early, but in late April, once you see new growth at the base, give lavender a light trim to shape the plant and encourage bushy growth. Avoid cutting into old wood, as it may not regenerate.
Hydrangea (macrophylla/mophead and lacecap): If not already done, you can prune in April by removing old flower heads and cutting back dead or weak stems to a strong pair of buds. Avoid cutting into stems that will flower this year, as most hydrangeas bloom on old wood.

Rose Pruning

There is still time to prune roses in April if this was not done in March. Start by inspecting the plant for frost damage, blackened stems, or crossing branches.

Remove any dead, diseased, or weak stems completely
Cut back healthy growth to strong, outward facing buds
Open up the centre of the plant to improve airflow and shape

This helps reduce the risk of fungal diseases and encourages stronger growth and more abundant blooms later in the season. For more detailed advice, see our guide to planting and caring for roses.

Tree Pruning

While most heavy tree pruning should be done during the dormant winter months, April is a great time for light pruning and tidying:

Remove dead, damaged, or rubbing branches on ornamental or young trees to improve shape and health.
Lightly shape young trees to guide balanced, upright growth as they establish.
Avoid pruning stone fruit trees like cherry, plum, and peach in April, these are best pruned in summer to prevent disease such as silver leaf.
Always use clean, sharp tools, and make angled cuts just above a bud or side branch.

This type of light gardening maintenance can prevent problems later in the season and keep your trees looking tidy and healthy.

How to Feed and Care for You Garden

Plants begin to grow quickly in April, so feeding them now will support healthy development and strong flowering in the months ahead.

Apply a general purpose fertiliser to beds and borders
Refresh pots and containers with fresh compost and slow release feed
Mulch soil to retain moisture and reduce weed growth
Check slug and snail protection as young shoots are vulnerable

Watering becomes more important as temperatures rise, especially for newly planted areas. Water early in the day to limit evaporation and help prevent fungal problems.

Extra Gardening Tips for April

April is a key month for building strong foundations in your garden. Small, consistent tasks now will make a noticeable difference in the months ahead.

Thin out seedlings to prevent overcrowding and encourage stronger, healthier plants. Giving each seedling enough space improves airflow and reduces the risk of disease.
Ventilate greenhouses and cold frames on warmer days to prevent overheating. Good airflow helps protect young plants from mould and damping off.
Keep an eye on night time temperatures and protect tender plants with fleece or cloches if frost is forecast. Sudden cold snaps can still occur in April in Ireland.
Plant herbs such as basil, parsley, and coriander in pots or raised beds for easy access. Regular harvesting will keep plants productive and encourage fresh growth.
Install a water butt to collect rainwater. April showers can quickly fill it, providing a sustainable and cost effective water source for the months ahead.
Divide and replant overcrowded perennials such as hostas, daylilies, and ornamental grasses. This helps rejuvenate older plants and gives you more plants to use around the garden.
Start training climbing plants like clematis and sweet peas onto supports while they are still easy to manage. Early guidance helps create a neater, more controlled display later on.
Refresh and top up mulch around shrubs and perennials to retain moisture, suppress weeds, and improve soil structure as temperatures rise.
Harden off young plants that were started indoors by gradually introducing them to outdoor conditions over a period of seven to ten days. This helps prevent transplant shock.
Label newly sown seeds and planted areas to keep track of what is growing where, especially if you are succession sowing crops.

Staying consistent with care and small tasks in April will help your garden establish well and continue to thrive into summer.
