‘Lawns don’t need watering!’ How to garden in a heatwave, from recycling bathwater to making the most of shade

TL;DR

  • Water in the early morning or late evening to minimize evaporation and allow water to soak into cooler soil.
  • Use a watering can instead of a hose to better control water usage and ensure plants receive adequate moisture.
  • Water deeply and less frequently to encourage plants to develop deeper root systems.
  • Collect rainwater or use greywater from washing vegetables or showering for watering.
  • Use moisture-retaining compost and apply mulch (like bark or compost) to keep soil cool and retain moisture.
  • Choose heat-tolerant plants, such as Mediterranean varieties, that require less water once established.
  • For lawns, raise the cutting height to allow grass to develop deeper roots and shade the soil.
  • Ponds are beneficial for wildlife and can be topped up with stored rainwater.
  • Move houseplants to shadier spots and consider moving them outdoors for the summer.
  • Create shade for patios and plants using climbers or screening materials.
