Here is where VGALive comes in; a 100% free (now and we are told forever) online vegetable plot management system and encyclopaedia.
VGA’s main function is to keep track of yearly crop growing cycles.
Users can record...
* what crop has been planted;
* where and when a crop was set and harvested; and
* a complete history of that any zone.
When considering what to plant next year, it’s easy to see what can safely be planted next, and, probably why it is free, the built in seed catalog makes it easy to plan ahead before the busy planting season arrives.
