Spring bulbs are beginning to bloom, and with each reminder that spring is on the way I think more about starting my vegetable garden. Every gardener knows that the question of when to plant is always a struggle. Maximizing the growing season while minimizing plant loss due to surprise cold snaps and frosts is always a balancing act. Living at high elevations can make this even more difficult, so I decided to do some research and see if I could get a better picture of what my garden and I are up against.
The first thing I needed to find was information about the temperature tolerances for vegetables. I found a great table at the Colorado State University Extension that provided acceptable germination temperatures as well as information on how temperature-hardy the young plants are. I created a floating bar chart in Grapher 12 to depict this information.
