Growing in June
Hi ,
2025’s spring was the sunniest on record, and that bodes brilliantly for a summer full of colour, growth, and time spent enjoying the great outdoors. June brings long days and plenty to do, whether you’re planting, pruning, or simply relaxing in the garden.
With warmer weather here, it’s important to water wisely. Early mornings or evenings are best for reducing evaporation, and a thorough soak at the base of plants is more effective than a light sprinkle. Prioritise pots, vegetable beds, and anything newly planted, and consider adding mulch to lock in moisture and keep roots cool.
Each Saturday, my gardening columns in the Daily Mirror and Daily Express are full of seasonal advice, practical jobs, and easy wins to keep your garden thriving through summer. You can find my latest columns here.
I’ve also got some wonderful events lined up this summer, with the first in Northern Ireland next week. It would be lovely to see you there. Follow the links below for more information on where I’ll be and when:
- Garden Show Ireland
- National Gardening & Outdoor Living Show
- Belvoir Castle Flower Show

Wishing you sunshine, colour, and joyful moments in your garden this June.
Happy gardening!
David

Gardening tip of the month
June Tomato Care
By June, tomato plants are well on their way. With the right support, feeding, and watering, you’ll set the stage for juicy harvests in the weeks ahead.
Tie in Weekly
Tomato plants can grow rapidly in June, especially in warm, bright conditions. Check plants every few days and loosely tie the main stem to its cane or support as it grows.
This keeps the plant upright and protects it from snapping. Use soft string or tomato clips to avoid damaging stems.
Remove Side Shoots
Cordon varieties need regular maintenance to stay productive. Look out for small shoots between the main stem and leaf branches.
Pinch these out cleanly with your fingers to prevent energy from going into leaf growth. This directs the plant’s focus into forming strong stems, then flowers, then fruit.
Start Feeding
Once the first truss of flowers has started to form fruit, begin a weekly feed using a high-potash tomato fertiliser. This encourages more flowers and better-quality tomatoes as the plant develops.
Liquid feeds can be added to your watering routine. Just follow the bottle’s instructions for best results.
Water Consistently
June heat can cause compost to dry out quickly, especially in containers. Avoid irregular watering, which can cause split skins or blossom end rot.
Water in the morning to allow leaves to dry off, reduce evaporation, and keep the root zone evenly moist. Mulch around the base to retain moisture on hot days.
