Summer’s here and it’s the best time of year to be out in the garden, with flowers blooming, bees buzzing and long days to enjoy it all! Keep your garden looking fabulous this summer with our top 15 gardening tips for June.
- Fill pots and hanging baskets with summer bedding plants for fantastic colour that will last for months. Trailing geraniums, petunias and lobelia love sunny spots and impatiens and begonias are great for shady spots. Feed 10-14 days with a high potash feed for maximum flowering (middle number).
- Harden off and plant runner beans, French beans, squash, courgettes and tomatoes.
- Keep on sowing salad greens, beetroot, and carrots to give you a supply all through summer.
- Feed tomatoes every 7-10 days with a high potash feed (middle number) to encourage fruit development. Container-grown vegetables like dwarf beans and zucchinis will also benefit from a fortnightly high potash feed – tomato feed works for them all!
- First early potatoes should be ready to harvest this month. Dig up one or two first to check how big they are, and if they’re too small, let them grow for a few more weeks.
- Harvest garlic and onion once the leaves turn yellow and start to flop over.
- Net strawberries as they start to ripen so that the birds don’t get to them before you can enjoy them.
- Weeds grow fast in summer, so keep them under control. On dry days, run a Dutch hoe over the soil to cut down annual weeds like spurge, chickweed, and hairy bittercress, and leave the weeds on the soil to wither.
- Deadhead repeat-flowering roses and pick sweet peas regularly so that they will keep on flowering all summer.
- Once hardy geraniums have finished flowering, cut them back to promote a flush of new foliage and flowers.
- Give wisteria its summer prune by cutting back all this year’s long whippy shoots to around 20cm long.
- Mow the lawn regularly, but in long spells of dry weather, mow less often and on a higher blade setting to reduce stress on the grass. If you have space, leave an area of lawn uncut to provide a home for insects and other garden wildlife.
- Prune summer-flowering shrubs like Philadelphus (mock orange), Weigela, and Forsythia once they’ve finished flowering. Cut back the flowered shoots to strong buds lower down and removing one in every 3-4 old stems to encourage new growth.
- Trim evergreen hedges to keep them neat, but always check first to make sure you aren’t disturbing any nesting birds.
- Water in the early mornings or evenings to reduce water loss through evaporation, and install rain barrels to conserve rainwater for use on the garden.
