June Gardening Jobs

With summer just around the corner, gardens across the country are bursting into life. Warmer temperatures and longer days mean rapid growth – but not just for your prized plants. Weeds, pests, and diseases are just as eager to take advantage of the season, so 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 the most important June gardening tasks, from caring for lawns to planting summer bedding and harvesting homegrown fruit and veg.

General Gardening Tasks for June 

Keep weeds under control: Weeds grow rapidly at this time of year, competing with your plants for light, nutrients, and water. Stick to a weekly weeding routine and use a selective weed killer where needed.

Stay on top of watering: As the weather heats up, make watering part of your daily routine, particularly for pots, containers, and hanging baskets.

Check for pests and disease: Warmer weather can encourage aphids, slugs, and fungal diseases. Keep an eye out for signs of trouble and act early.

Lawn Care in June

Your lawn will be thriving now, so June is all about maintenance and repair: 

•  Mow regularly: Frequent mowing helps encourage a thicker, healthier lawn. Avoid cutting too short during dry spells. 
•  Tackle lawn weeds: If dandelions or clover are popping up, treat them with a selective weed killer that won’t harm your grass. 
•  Patch bare spots: Use our A1 Lawn Patch Repair Seed Mix to overseed any thin or patchy areas. 
•  Apply a summer lawn fertiliser: Our A1 Lawn Spring/Summer Fertiliser helps strengthen your turf and reduces the risk of common lawn diseases like Red Thread. 
•  Water wisely: Only water your lawn if needed and if there are no local water restrictions. Early morning or late evening is best to reduce evaporation. 
•  Move garden furniture: Rotating chairs and tables helps prevent dead patches and compaction.

Trees, Shrubs and Hedges

• Deadhead fading flowers: Removing spent blooms from shrubs like lilacs, rhododendrons, and roses encourages fresh growth and prolongs flowering.
• Prune spring-flowering shrubs: Tidy up any shrubs that have now finished blooming to keep their shape and promote new growth.

Beds, Borders, and Bedding Plants

• Plant summer bedding: Now’s the perfect time to plant vibrant annuals for a splash of summer colour – think petunias, marigolds, and lobelias. Keep them well-watered, especially in the first few weeks.
• Deadhead regularly: Removing faded flowers keeps your borders looking their best and encourages continuous blooms.

Support and Divide Perennials

• Stake tall plants: Fast-growing perennials like delphiniums and lupins need support to prevent flopping. Use garden canes and soft ties to prop them up gently. 
• Take softwood cuttings: Propagate new plants from healthy, non-flowering shoots of shrubs such as fuchsias or hydrangeas.
• Divide early-flowering perennials: If plants like lungwort or primulas have finished flowering, lift and divide them to rejuvenate clumps and improve flowering next year.

Roses: Train and Tidy

• Train climbing roses: Tie in fresh growth on climbing and rambling roses to avoid damage and encourage flowering along the stems. 
• Use proper ties: Choose plastic or fabric ties rather than string, which can degrade over time.

Grow and Harvest Your Own

June is a rewarding month in the veg patch: 

• Harvest early crops: Start picking radishes, lettuce, spring onions, peas, early potatoes, and asparagus.
• Keep sowing: Fill any gaps with quick-growing salad veg or sow another batch to extend the harvest season.
• Water and feed: Ensure consistent watering for your crops, and add a balanced fertiliser to encourage strong, healthy growth.

Enjoy Summer Fruits

• Pick strawberries: Greenhouse-grown strawberries are ready now, with outdoor ones not far behind. Harvest with a short stalk to help them stay fresh longer.
• Harvest rhubarb, redcurrants, and gooseberries: Pick ripe fruits gently and avoid stripping plants completely, which can reduce next year’s yield.
• Protect ripening fruit: Use netting or mesh to keep birds and pests at bay.

Prepare for the End of Summer

It might feel early, but some forward planning will keep your garden in great shape later in the year: 

• Lift spring bulbs: Tulips and hyacinths can be lifted and stored in a cool, dry place. Leave daffodils and snowdrops in situ.
• Clear out spring bedding: Remove spent forget-me-nots, wallflowers, and other early bloomers and compost them to make space for summer plants.

June is one of the busiest and most beautiful months in the gardening calendar. A little regular maintenance now means you can enjoy lush lawns, colourful borders, and fresh produce all summer long. So grab your trowel, make the most of the warm weather – and don’t forget to take time to sit back and admire your hard work.
