Lacking Green Fingers? You Need Willow, the Smart Sensor Which Tells You Exactly What Your Plant Needs.

on

 We’ve all been there: staring at a drooping houseplant, completely unsure if it needs more water, less water, or just a different spot in the living room. Today, plant care brand Plant With Willow is ending the guesswork with a simple, £35 smart sensor that translates what your plants are feeling into clear, actionable notifications on your phone, and gives you a laugh to boot.

While our homes have gotten smarter with automated heating and lighting, plant care has remained a frustrating game of trial and error. The Willow Sensor changes that. By sitting discreetly in the soil, it monitors the five things that actually keep plants alive: moisture, light, temperature, humidity, and nutrients.

I am the queen of gadgets and I love plants but am not so good at keeping them alive or even looking healthy. Apart from Peace Lilies which I swear are the easiest plants to keep as they literally droop when they need water and perk up within a very short time when you hurl some H2O at them.

I rehome lots of plants from  family members who work at a supermarket. There, plants on death row (coming to the end of their "best before date" or which look too near to expiring to sell) are offered free to employees. I'll be honest I cant revive all of them but they at least get a second chance. I'm hoping my new Willow Starter Kit (GIFTED) will give more of them a chance of life.

So how does it work?

Instead of relying on generic weekly watering routines that lead to root rot, you stick in the sensor, pair it to a hub, download the app and off you go! Willow pings your phone exactly when your specific plant needs attention. It essentially acts as a baby monitor for your houseplants, removing the anxiety of plant care by telling you exactly what to do and when to do it. Now, you don't need to be a botanist to keep your living space green and vibrant, and you can finally ditch the guilt of accidentally killing your greenery.

You can name your plant, set it to direct or sassy mode and choose to let Willow tell you went to water and feed it, whether it's too hot, not humid enough etc. Basically, keep it alive. You can also opt for a reasonably priced upgrade plan which helps you grow plants and has lots of neat additional features and information options - you could even speak to a plant expert. 

Either way the app has lots of useful info about all things houseplant related which could just turn your fingers green enough to keep multiple plants alive. If not, you can just buy more sensors and link them to your hub and then be both smug at your home jungle and entertained by your chatty plants. I obviously chose sassy mode - here's a screenshot of my latest interaction with Tiger, a Ctenanthe Setosa (often known as  "Never Never Plants") who now lives in my bathroom after he told me he was too cold and dry in my lounge.

Why Willow is the Ultimate Plant Saver:

  • No More Overwatering: The number one plant killer, solved. The app alerts you when the soil is actually dry, and confirms when you’ve watered it just enough.
  • The "Happiness Score": Open the app for an at-a-glance health check. If the score drops, Willow tells you how to fix it before visible damage appears.
  • Find the Perfect Light: Willow measures light intensity every minute, taking the mystery out of "bright, indirect sunlight" so you can find the perfect spot in your home.
  • Grows With Your Jungle: The £34.99 Starter Pack includes one Hub and one Sensor, but the Hub can support up to 40 sensors for those with a serious houseplant addiction.
