From the app’s home page, you can choose to view plants alphabetically (by clicking “All Plants”), by sowing month or by crops that can be planted immediately in your area. You can also mark crops as your favorites, and easily view just your favorites list.  









Click on any crop or plant in the When to Plant app, and you can see the “window” of time in which you can direct sow, start seeds indoors, plant out, and harvest that crop based on the frost dates in your ZIP code.  

The different colored lines show different planting info: The blue line shows when you can start seeds indoors, the green line shows when you can direct sow seeds or plant out transplants, and the orange line shows the range of possible harvest dates for the crop.  







The When to Plant app also includes growing information on each of the dozens of crops and plants included. Click on a crop to learn its crop family, preferred soil type, sun requirements, sowing instructions, troubleshooting tips, recommended spacing, how to harvest, and more. 







The app provides easy access to National Weather Service long-range forecast maps (U.S. only). You can see maps projecting temperature, precipitation, weather hazards and drought.
