Why plants struggle

Most plants don't die of neglect.They die of guessing.

Over-watering, the wrong spot, dry air - the things that hurt a plant are the hardest to see. Willow can watch them for you, so you stop guessing and start knowing.

Watering is a guessing game

Too much or too little is the quickest way to kill a plant. Willow can read the soil and tell you the moment it's time.

The right spot is hard to spot

Light shifts through the day and the seasons. Willow can measure it, so every plant lands where it will thrive.

Rooms change with the weather

Dry air and temperature swings stress plants. Willow can spot it before the leaves do.

I’ve always been the one who can’t keep houseplants alive so gave up having any. Now I have 8 sensors and even more plants. They all look healthy. Willow is fun, informative, and such a clever idea. I love the humorous remarks. My snake plant can be a bit bossy though!

Willow isn't just another sensor; it doesn't just measure moisture, it measures the "mood" of your plants. It tells you if they are happy or sad, literally using smiley faces on the pot itself within the app. It notifies you if they need water, more or less light, or fertilizer. It identifies your plants with an accurate algorythm and gives professional advice to help them thrive. Plus, it adds a touch of irony, giving the plants a personality.

Works well, I can no longer forget about my plants as the Willow sensors tell me by notifying my phone when my plants need to be watered or something else like need more sunlight. Highly recommend.

I used to kill plants merely by looking at them. Now, my monstera game is strong and I've graduated to four living plants that yell at me when I'm being neglectful. Cannot recommend this system highly enough!!!

I love how easy this device makes plant care. It feels like my babies talk to me. It has totally changed the way I water them and my plants seem so much healthier. The only drawback is the light sensor, bushy larger plants mean the sensor is under the leaves and so the light readings are useless, I’m not sure there is even a way to fix this for larger plants but I’ve purchased a separate light meter and now have it all worked out.

My plants have been thriving since investing in Willow, and as someone who used to struggle to keep any houseplant alive this is saying something. The app instructions are easy to follow, and it has given me the confidence to get more plants to brighten up my home.
