As the UK braces for a mini-heatwave with temperatures potentially reaching 30°C, gardeners are seeking ways to protect their plants from wilting. A simple solution involves using mushroom-infused water, according to experts.
Waine Delaney from Monotub suggests soaking a handful of chopped edible mushrooms in a watering can for 24 hours. The resulting liquid, applied to roots after sunset, acts as a hydration pod, slowly releasing moisture and reducing evaporation during peak heat.
Mushrooms are 85-90% water and rich in nutrients like potassium, selenium, magnesium, and phosphorus. These elements create a gentle tonic that replenishes minerals without the risk of over-fertilising. The infusion also introduces mycelium, which improves soil water retention and plant absorption.
Even if heavy rain follows the heatwave, potted plants may not get enough water due to leaf canopy redirecting rainwater. Simon from Walking Talking Gardeners recommends tapping terracotta pots: a ringing sound indicates dryness, while a dull thud means adequate moisture.
Overwatering can lead to root rot and fungal issues, so the tapping method helps avoid this. By combining mushroom water with proper watering cues, gardeners can keep their plants thriving through the hot spell.
