June is a great time for gardening in the UK, as the weather is typically warm and sunny. Here are some tasks that can be done in the garden during June:

1. Plant summer bedding plants: June is the perfect time to plant summer bedding plants such as petunias, marigolds, and geraniums.
2. Deadhead flowers: Regularly deadhead your flowers to encourage new growth and prolong the blooming season.
3. Water: With the warmer weather, make sure to water your plants regularly to prevent them from drying out. Water in the early morning or late evening to reduce evaporation.
4. Harvest early crops: Harvest early crops such as lettuce, peas, and strawberries as they ripen.
5. Prune spring-flowering shrubs: Prune spring-flowering shrubs such as lilacs and forsythia after they have finished blooming.
6. Weed: Keep on top of weeding to prevent them from competing with your plants for nutrients and water.
7. Feed plants: Feed your plants with a balanced fertilizer to encourage healthy growth and blooming.
8. Control pests: Keep an eye out for pests such as aphids and slugs and take appropriate measures to control them.

By doing these tasks in June, you can help ensure a beautiful and productive garden throughout the summer months.
