Summer gardening tips
Summer is one of the most rewarding seasons for gardeners in Ireland. Mild temperatures, a good balance of sunshine and showers, means your garden is likely bursting into life. The Irish weather can be fickle so here are a few general tips on making the most of things this summer.
General Tips
- Water early or late: Water in the morning or evening to reduce evaporation.
- Mulch: Use bark, straw, or compost to retain moisture and suppress weeds.
- Check rain levels: Irish summers can be dry in spells; if there’s less than 1″ (25mm) of rain a week, water deeply.
Lawn Care
- Raise the mower: Keep grass slightly longer (5–7cm) to retain moisture and resist drought.
- Feed your lawn: Use a summer feed high in nitrogen (early summer) or a balanced feed.
- Spot treat weeds: Remove them before they flower and spread.
Flowers & Bedding Plants
- Deadhead regularly: Encourages new blooms in annuals like petunias, geraniums, and marigolds.
- Feed containers weekly: Use a high-potash feed like tomato food for planters and hanging baskets.
- Keep an eye on slugs: Especially after rain; use barriers or organic slug pellets.
Vegetable Garden
- Harvest frequently: Pick courgettes, beans, lettuce, etc., to encourage more growth.
- Sow succession crops: Salad leaves, radish, beetroot, and spring onions can still be sown.
- Support taller plants: Tie up tomatoes, peas, and beans to prevent wind damage.
Fruit & Shrubs
- Net soft fruits: Protect strawberries, raspberries, and currants from birds.
- Prune stone fruits: July is good for pruning cherries and plums (reduces risk of silver leaf disease).
- Keep an eye on aphids: Spray with soapy water or introduce ladybirds.
Greenhouse/Polytunnel
- Ventilate well: Open doors and vents daily to prevent mildew.
- Dampen floors: Helps control temperature and humidity.
- Watch for whitefly and red spider mites: Use yellow sticky traps or natural predators.
Wet Weather Adaptations
- Improve drainage: Raise beds or use gravel paths to prevent waterlogging.
- Space plants well: Improves airflow and reduces fungal diseases.
