With the Met Office predicting a higher-than-normal chance of a hot summer in the UK, it’s good news for staycationers, a bit more concerning for gardeners.
The Met Office says it could be a hot one! Are you prepared to protect your beloved plants and flowers? Protecting your garden during a UK heatwave is all about smart planning, water conservation, and temporary adjustments. With a few proactive steps, you can help your plants not just survive but even thrive when the temperatures rise. And remember – many gardens bounce back quickly with a little rain and cooler weather, which, in true British fashion, is probably just around the corner!
With a few smart strategies, you can shield your garden from the worst of the heat and keep it thriving through the hottest days. Here’s how:
Water early, deeply, and efficiently
During a UK heatwave, especially with hosepipe bans becoming more common, it’s important to make every drop count:
- Water early in the morning or late in the evening when evaporation is at its lowest.
- Use a watering can or drip irrigation to deliver water directly to the roots and avoid wastage.
- Apply water deeply but less frequently to encourage plants to develop deeper roots, making them more resilient to drought.
Tip: Reuse grey water from baths or washing up—just avoid harsh chemicals and use it on ornamental plants only.
Mulch your soil
Mulching is one of the most effective ways to retain soil moisture and regulate temperature:
- Apply a thick layer of mulch (e.g. bark chips, compost, or well-rotted manure) around the base of plants.
- This helps to reduce evaporation, suppress weeds, and keep roots cool.
Tip: Mulch after watering to trap the moisture in the soil.
Provide shade for sensitive plants
Many UK garden plants, especially those not native to hotter climates, can suffer in full sun:
- Use shade cloths, garden umbrellas, or even old bed sheets to protect delicate plants during the hottest part of the day.
- Move potted plants into shadier spots or indoors temporarily.
Tip: Group pots together to create a microclimate and reduce moisture loss.
Don’t Overfeed or Prune
During high heat, plants go into survival mode, and feeding or pruning can stress them further:
- Avoid feeding during a heatwave—it can stimulate growth that the plant can’t support in hot, dry conditions.
- Hold off on heavy pruning, as this can expose more of the plant to intense sunlight and remove stored water reserves.
Look After Your Lawn
UK lawns often turn brown during a heatwave, but that doesn’t mean they’re dead:
- Grass is surprisingly resilient and usually recovers after rain.
- Don’t mow too short—leave grass longer to provide shade to the soil.
- Consider ditching the hosepipe and embracing a more natural lawn during dry spells.
Choose Heat-Tolerant Plants
Plan ahead for future summers by incorporating drought-resistant plants into your beds and borders:
- Great UK options include lavender, sedum, rosemary, euphorbia, and ornamental grasses.
- Native wildflowers also tend to be more resilient and attract pollinators.
