The smart garden weather & frost alert app for your plants.
Standard weather apps check the air high up, often missing the ground-level frost that kills your plants first. The My Cozy Plant app tracks the actual weather right where your garden grows. Get clear, early alerts for surprise freezes, summer heatwaves, and high winds, so you know exactly when to cover and protect 225+ different plants.
Smart Watering Guide
No more guessing when to water. By tracking local sun, wind, and temperature, our app calculates exactly how fast your soil is drying out. Know when to water deeply and when to hold off, saving your plants from wilting or root rot.
Container vs. Ground Tracking
Roots in pots freeze much faster than those planted in the ground. Tell the app where your plants are growing in pots, garden beds, or a greenhouse, and we will adjust your plant frost protection alerts automatically.
Hourly Weather Charts
Track your local microclimate temperature, wind, and rain with easy-to-read hourly graphs. Get warned about severe, plant-killing freezes (black frost) and intense summer sun before they can damage your garden.
Weather Care Guides for 225+ Plants
From Arugula to Zinnia, the app knows the exact cold hardiness and heat limits for every plant in your garden, no matter the season.
Designed for serious gardeners
A clean, simple interface that puts your plant safety first.
Why regular weather apps fail gardeners
Standard forecasts measure air at 6ft high. On clear, calm nights, the temperature at ground level can be 3°C to 5°C (5°F - 9°F) colder. This app bridges that gap by calculating soil-level risk, ensuring you never wake up to a surprise frost again.
