Smart homes have become very good at managing lighting, heating and security, yet plant care has mostly been left to intuition, routines and crossed fingers. That gap is exactly what **Plant With Willow** is aiming to close with **Willow**, a compact sensor designed to take the guesswork out of keeping houseplants healthy.
Rather than relying on fixed watering schedules or vague advice, Willow monitors real conditions around each plant and turns that data into simple, timely guidance through a companion app. The result is plant care that responds to what is actually happening, not what we hope is happening.
How Willow Works
At the heart of the system is a slim sensor that sits discreetly in the soil. It continuously tracks the factors that matter most to plant health, including soil moisture, light intensity, temperature, humidity and nutrient levels.
Data is collected every few minutes and analysed in the Willow app. Instead of generic reminders, users receive clear alerts telling them when to water, move or feed a plant based on its real needs at that moment. It is a small shift in approach that makes a big difference, especially for anyone who has ever overwatered a perfectly healthy plant.
Smarter Feedback, Not Just Notifications
One of the more thoughtful touches is what happens after you water. The app confirms whether moisture levels have reached the optimal range, removing the usual uncertainty that comes with plant care. Over time, Willow also analyses longer-term soil trends, helping identify nutrient deficiencies or absorption problems before they become visible to the eye.
Light levels are measured every minute, making it easier to position plants correctly, while temperature and humidity monitoring ensures sudden environmental changes do not go unnoticed. Each plant is also given a simple happiness score, providing an at-a-glance snapshot of overall health that works equally well for beginners and seasoned plant owners.
Designed to Grow With Your Collection
Willow is clearly designed with scalability in mind. The Starter Pack includes one Sensor and one Hub, with the Hub capable of supporting up to 40 Sensors. That makes it just as suitable for a single prized houseplant as it is for a growing indoor jungle.
It is a sensible, modular approach that avoids locking users into buying multiple hubs as their collection expands.
Price and Availability
The Plant With Willow Starter Pack is priced at £34.99 and is available now from plantwithwillow.co.uk.
For anyone who enjoys having plants at home but would like a bit more certainty and a lot less guesswork, Willow feels like a natural extension of the smart home. Sometimes, the smartest upgrade is simply knowing when to water.
