Gardening in June is a busy time for gardeners. The summer season will start on June 20th this year with the summer solstice giving us the longest day of the year. Flowers are in full bloom and the vegetable garden is bountiful with crops due to the extra sunlight and warmer temperatures.
What to do now
The summer season can be hot and dry in most places. During this month, check beds, borders and containers daily and water them if the soil is dry. Garden weeds will compete with your plants for precious water and sunlight, so keep on top of the weeding. Mow and water the lawn weekly. Keep greenhouses ventilated and provide some shade for plants inside during the hot summer months.
- Water the lawn in the morning once a week.
- Add a slow release lawn fertiliser.
- Aerate areas which see the most footfall with a garden fork.
- Keep on top of weeds appearing on the lawn.
Garden lawns benefit from a deep watering just once a week early in the morning. Over-watering and watering in the evening can invite lawn diseases and allow weeds to take root. Regular mowing during this month will encourage a healthy lawn. Apply a slow release, spring, summer fertiliser and mow the lawn weekly. Aerate areas which are used as regular paths with aerator sandals or a garden fork. This will avoid the lawn becoming compacted and worn in well used areas. Good lawn maintenance will help to keep the weeds under control. Pull out weeds when they first appear.
Beds and borders
- Lift and store spring flowering bulbs.
- Plant out summer bedding plants.
- Deadhead perennials to encourage further flowering.
- Check roses for black spot. Deadhead to keep roses flowering longer.
- Keep hanging baskets and containers well-watered.
- Stake out tall and trailing plants to give support for growth.
- Cut back geraniums after flowering to encourage more flowers.
- Take cuttings from perennials.
- Hoe beds and borders regularly to remove weeds.
Gardening in June is the perfect time to move seedlings outside during the day to harden off. Plant out well-established seedlings which have been grown in the greenhouse. Place in supports for tall growing plants and climbing varieties. Deadhead and prune perennials to encourage more blooms throughout the coming months. Lift out and store spring flowering bulbs. Naturalised clumps can be lifted and divided then place back in the ground or relocated elsewhere in the garden. Plant out perennials ready for next spring.
- Keep on top of weeds, hoe the soil regularly and pick out weeds.
- Water crops deeply, ideally with rainwater or non-chlorinated water.
- Harvest salad crops, strawberries and raspberries.
- Pinch out side-shoots on tomatoes.
- Plant out brassicas like cabbage, broccoli and brussels sprouts.
- Continue succession sowing of salad crops.
- Sow winter crops, such as carrots, swede and turnips.
Check the vegetable patch regularly for weeds during this month as they will compete with vegetables for precious space and water. The vegetable garden is in full swing now and more seedlings are ready to be planted out. Salad crops and herbs are ready to be harvested. Tomato plants are becoming well established and will need to have their side-shoots pinched out. Continue to sow salad seeds to receive a larger yield over the coming months. Sow winter crops in bare spaces ready to provide a winter bounty.
Weeds and pests
Weeding is a top priority while gardening in June. With the extra sunshine and summer showers, weeds will take root in any available space.
Keep an eye out for gooseberry sawfly, aphids and caterpillars. Checking plants daily will mean you can remove garden pests by hand without needing to use pesticides.
Garden birds are feeding their young now and will help with pest control in the garden as they spend the day hunting down caterpillars, larvae and greenfly. Before trimming thick hedgerow or trees, take the time to check first that there are no bird nests in the foliage.
Continue to provide birds with nuts and seeds and a fresh supply of water throughout the summer months.
