Willy the Worm Plant Watering Sensor is a playful terracotta moisture indicator that helps you know exactly when your plants need watering. Simply place Willy in the soil and watch the colour change. Darker when the soil is moist and lighter when it’s time to water.
Ideal for beginners or busy plant owners, this easy to use sensor helps prevent both overwatering and underwatering, keeping houseplants healthier for longer.
How to use:Insert Willy into the potting mix near the plant roots. Check his colour before watering, and allow him to dry out between waterings for best results.
