As the UK braces for a mini-heatwave, gardeners may be wondering how to keep their plants hydrated and healthy during the hot weather. The Met Office forecasts temperatures could reach 30C in parts of the UK, with hot weather continuing over the next few days.
The Mushroom Water Trick
Waine Delaney, from mushroom cultivation experts Monotub, suggests using mushroom-infused water as a secret weapon. Simply grab a handful of edible mushrooms, chop them up, and soak them in your watering can for 24 hours. Then, drench the roots of your outdoor plants or containers after sunset.
Wayne explains: "Whether they are dry or fresh, mushrooms are natural sponges and are made up of 85-90% water. When placed in the water of a watering can, mushrooms act as a 'hydration pod'. This means that mushroom-infused water slowly releases into the soil, reducing evaporation during peak heat hours."
Nutrient Benefits
Mushrooms are packed with potassium, selenium, magnesium, and phosphorus. These nutrients seep into the water, forming a gentle tonic that replenishes minerals plants need during high temperatures, without the harm of stronger fertilisers. The infusion also releases mycelium, fungal threads that help soil retain water and improve plant absorption.
Genius Pot Watering Tip
Simon, a horticulture expert from Walking Talking Gardeners, shares a traditional method to check if pots need watering. Tap the pot: if it rings, it's dry; if it thuds, it's watered. This avoids overwatering, which can cause root rot and fungal issues.
Even after heavy rain, container plants may not get enough water due to the canopy effect of leaves. Use these tips to keep your plants thriving during the heatwave.
