June in the Garden

June brings long, warm days and the garden's peak bloom, but also the first real test of summer's heat. This month is all about maintaining momentum while preparing for potential dry spells – your garden’s vitality depends on smart, timely care.

Deadhead for Continuous Bloom

Focus on flowers that need regular pruning

• Remove spent blooms from roses, lavender, and hardy geraniums to encourage a second flush of flowers.
• Cut back dead flowers on herbaceous perennials like delphiniums and hellebores to tidy the border and prevent self-seeding.
• For annuals like petunias, pinch off dead heads to keep them bushy and flowering longer.

Vegetable Patch Vigilance

Key tasks for your summer harvest

• Water deeply at the base of beans, peas, and courgettes every few days, avoiding leaves to prevent mildew.
• Stake tomatoes and runner beans as they grow, using bamboo canes or wigwams for support.
• Harvest early crops like peas and radishes regularly to encourage more production.

Watering Wisdom

Avoid common summer mistakes

• Water early morning or late evening to reduce evaporation and fungal risk.
• Aim for deep, infrequent watering (once a week) rather than light daily sprinkles.
• Mulch around plants with well-rotted garden compost or straw to retain moisture and suppress weeds.

Pest & Disease Checks

Stay ahead of common June issues

• Inspect under leaves for aphids on roses and soft fruits; spray with a strong jet of water or use natural predators like ladybirds.
• Check fruit trees for signs of silver leaf disease – remove and burn affected branches immediately.
• Lift potato haulms (stems) after flowering to encourage tuber development.

Lawn Care for Summer

Maintain without stressing the grass

• Raise your mower height to 3cm (1.2 inches) to shade roots and reduce water loss.
• Scarify (rake) only if the lawn is very thick – avoid heavy aeration in dry weather.
• Fill bare patches with a mix of lawn seed and topsoil after a light rain.
