June Gardening Jobs

With summer just around the corner, gardens are bursting into life. Longer days and warmer temperatures mean rapid growth - not just for your prized plants, but for weeds, pests, and diseases too. Staying on top of essential gardening jobs in June is key to maintaining a healthy, vibrant outdoor space. In this guide, we’ll walk you through everything you need to do this month - from lawn care and planting to pest control and harvesting your own fruit and vegetables.

Weed, pest, and disease control

• Weeds grow rapidly in June, competing with plants for light, water, and nutrients. Stick to a weekly weed treatment routine and use selective or total weed killers as needed.
• Marestail/horsetail can become troublesome this time of year. Professional options like Kurtail Evo (glyphosate-based) are highly effective. Non-professional alternatives include SBK Brushwood Killer, or Kurtail Lawn, which are glyphosate-free.
• Total weedkillers like Roundup ProActive work well on paths, patios, driveways, non-cropped land, and general amenity areas.
• Selective weedkillers target weeds without harming surrounding grass or vegetation. Products like Stapler are effective against a wide range of annual and perennial weeds.
• Always stay vigilant for pests and signs of disease. Aphids, slugs, and fungal infections thrive in warm weather—early action is essential.

Watering and maintenance

• As temperatures rise, make watering part of your daily routine, particularly for pots, containers, hanging baskets, and newly planted bedding.
• Check soil moisture and water deeply in the early morning or late evening to reduce evaporation.

Your lawn will be thriving now, so focus on maintenance and repair:

• Mow regularly: Frequent mowing encourages a thicker, healthier lawn. Avoid cutting too short during dry spells.
• Control weeds: Use selective weed killers to remove dandelions, clover, or other unwanted plants.
• Patch bare spots: Overseed thin or patchy areas with mixes such as A1 Lawn Patch Repair Seed Mix.
• Fertiliser: Apply a balanced summer fertiliser like A1 Lawn Spring/Summer Fertiliser to strengthen turf and reduce the risk of common lawn diseases, including red thread.
• Check for pests and disease: Leatherjackets and chafer grubs can damage lawns. Biological control options, such as nematodes, are effective solutions.
• Move garden furniture: Rotate chairs and tables to prevent dead patches and soil compaction.

• Deadhead fading flowers: Shrubs like lilacs, rhododendrons, and roses benefit from removed spent blooms.
• Prune spring-flowering shrubs: Tidy up any shrubs that have finished blooming to maintain shape and encourage new growth.
• Training wall plants: Guide climbing plants in the desired direction to ensure strong growth.

• Plant summer bedding, Now is perfect for petunias, marigolds, lobelias, and pansies (for winter/spring colour). Keep them well-watered in the first few weeks.
• Deadhead regularly, Removing faded flowers encourages continuous blooms and keeps borders looking fresh.
• Tidy spring-flowering perennials, Cut back old growth to prepare for summer.
• Stake tall perennials, Fast-growing plants like delphiniums and lupins may need support with garden canes and soft ties.
• Train climbing and rambling roses, Tie in fresh growth to prevent damage and encourage flowering along stems.
• Use proper ties, Plastic or fabric ties are better than string, which can degrade over time.

• Harvest early crops: radishes, lettuce, spring onions, peas, early potatoes, and asparagus.
• Keep sowing quick-growing salad vegetables to extend the harvest season.
• Water consistently and add balanced fertiliser to promote strong, healthy growth.
• Pick strawberries: Greenhouse-grown berries are ready, with outdoor strawberries following soon. Harvest with a short stalk for longer freshness.
• Harvest rhubarb, redcurrants, and gooseberries carefully—avoid stripping plants completely to protect next year’s yield.
• Protect ripening fruits using netting or mesh to deter birds and pests.

June is one of the busiest and most rewarding months in the gardening calendar. By keeping on top of these tasks, you can enjoy lush lawns, colourful borders, and fresh homegrown produce all summer long. With a little care and planning now, your garden will be in its full glory before the peak of summer arrives.
