Essential Gardening Jobs for June in the UK

June is a peak growing season in the garden, with plants flourishing and flowers in full bloom. The longer, warmer days mean there’s plenty to do to keep your garden looking its best. Here are the essential tasks to focus on this month:

1. Lawn Care

• Continue mowing the lawn regularly, adjusting the cutting height to prevent stress during dry spells.

• Water the lawn during prolonged dry periods to keep it green and healthy.

• Apply a summer lawn feed if needed to encourage strong growth.

2. Planting and Sowing

• Plant out summer bedding plants like petunias, begonias, and fuchsias for vibrant colour.

• Sow biennials such as foxgloves and wallflowers for next year’s display.

• Keep succession sowing salad crops, carrots, and radishes to ensure a continuous harvest.

• Transplant young vegetable plants such as tomatoes, courgettes, and peppers into their final positions.

3. Pruning and Deadheading

• Deadhead roses and summer-flowering plants to prolong blooms.

• Prune spring-flowering shrubs like lilac and weigela after flowering.

• Cut back spent stems of perennials to encourage a second flush of flowers.

4. Watering and Mulching

• Water plants deeply in the morning or evening to reduce evaporation.

• Use mulch around plants to retain moisture and suppress weeds.

• Keep an eye on potted plants, as they dry out quickly in warm weather.

5. Greenhouse and Indoor Plants

• Provide adequate ventilation in greenhouses to prevent overheating.

• Shade plants if temperatures rise too high to avoid scorching.

• Keep feeding container plants and hanging baskets with liquid fertiliser.

6. Supporting Wildlife

• Top up bird baths and ponds with fresh water during warm weather.

• Leave some wild areas in the garden to attract pollinators and beneficial insects.

• Plant nectar-rich flowers such as lavender, echinacea, and buddleia for butterflies and bees.

7. General Maintenance

• Tie in climbing plants like clematis and sweet peas as they grow.

• Keep weeds under control by hoeing or hand-weeding regularly.

• Inspect plants for pests such as aphids and slugs, and take action if needed.

June is a rewarding month in the garden, with lush growth and beautiful blooms everywhere. By staying on top of these key tasks, you’ll ensure a healthy, vibrant garden all summer long. Happy gardening!
