The UK is set to experience a mini-heatwave, raising concerns for gardeners about how to keep their plants healthy. Waine Delaney from Monotub recommends using mushroom-infused water as a natural hydration method. This involves steeping chopped edible mushrooms in water for a day, creating a nutrient-rich solution that helps plants retain moisture and absorb essential minerals like potassium and magnesium. Additionally, horticulture expert Simon advises checking moisture levels in terracotta pots by tapping them; a ringing sound indicates dryness, whereas a dull thud suggests adequate watering. This approach echoes traditional gardening practices and aims to prevent issues like root rot caused by overwatering. With the forecast predicting a hot summer, these strategies could be vital for maintaining plant health.
