The longest day of the year falls on June 20th, bringing warmer temperatures and extra sunlight. Flowers are blossoming, there’s lots to harvest in the vegetable garden, and keeping on top of bolting plants is a priority — particularly weeds!
There’s plenty to keep you busy in the garden in June, but also plenty to sit back and enjoy! With the longest day bringing extra hours of warmth and sunshine, and you can start planting in earnest.
Here are our top picks of seasonal things to sow and grow in the garden this month:
In the greenhouse/indoors
- Sow winter-flowering pansies in seed trays so they’ll be ready for your winter containers.
- It might seem a bit early, but start thinking about spring flowers for next year. Sow perennial seeds such as aquilegia, bellis, Canterbury bells, delphiniums and lupins indoors for flowering next year.
- Sow perennial scabiosa in pots or trays for bee and butterfly friendly flowers.
- For flowers that bridge the gap between spring and summer try growing forget-me-nots, foxgloves, Dianthus plants (sweet Williams) and wallflowers in seed trays now, for colour next year.
- Now there is space on windowsills again, think about sowing biennials for next year.
Direct sow outdoors
- It’s not too late to direct sow calendula, Candytuft ‘Dwarf Fairyland Mixed’, clarkia (Godetia), larkspur and limnanthes for a show of flowers later this summer.
- Nasturtiums are easy to grow in containers or direct sowings, and quick to flower — use them in beds, containers, baskets, and the vegetable plot.
- Scatter nigella seeds in your borders now for some striking blue late-summer flowers.
- Grow the tallest sunflower from direct sowings — great fun for the kids!
- Now that the risk of frost has passed, plant out any remaining summer annual bedding plants.
