The When to Plant app from Mother Earth News gives you the best planting times for vegetables, herbs, fruit, cover crops and common companion planting flowers. It uses a database of almost 5,000 weather stations across North America to locate average frost dates for your garden from the nearest station, and calculate the best range of planting dates for each crop

Main features:

Planting dates are calculated using average frost data for your specific ZIP code, which is much more accurate than relying on the USDA Winter Hardiness Zones system

When to Plant can split cool-season crops into separate spring and fall planting ranges for areas that experience long growing seasons and hot summer temperatures

Full growing information for more than 120 vegetables, herbs, fruit, cover crops and companion planting flowers

For each plant, the app includes advice on the best soil type and sun requirements, sowing instructions, troubleshooting tips, and how to harvest

Multiple display options, so you can see plants listed alphabetically or by sowing month, or choose to view just what can be planted right now in your area

Create a favorites list of the plants you commonly grow for quick access to information

Easy access to National Weather Service long-range forecast maps (U.S. only)

Please note: because When to Plant uses averaged frost data to calculate planting times it it not suitable for areas with sub-tropical climates or where frost is not experienced.

No longer working..?


Has this app broken or been abandoned? Used to have it and it was great. Re-downloaded it and it can’t identify my location to get started.

Doesn't work


Keeps placing me in Africa, while I live in Maine. Frustrating and a waste of $

Great info but buggy


There is a lot of great info here. However, the app is buggy. First/last frost dates were incorrect for my area, which causes incorrect planting dates. Although frost dates can be adjusted in app settings, the dates change back to the incorrect ones every time the app is closed and re-opened. Disabling location services in the Privacy menu fixes this on the iPhone version, but the iPad version provides no way to disable location services.

Also, the app takes forever to open on the iPad.

A potentially very useful app that is marred by annoying interface issues.
