The Links Between Phenology and Gardening

For those of you who do not know phenology is the study of the changing of the seasons.  Many believe it to be the oldest area of science.  For early humans would have needed to know when nature was changing in order to adjust his/her lives accordingly.  With the invention of agriculture early humans became even more dependent upon the study of phenology.  Signs in nature would have let them know when to plant different types of seeds or when to begin to harvest the crops that they had planted so many months before.  

which has some good information that the author has collected over the years and the table below details some of she has collected.

Also for more information on the study of phenology see Naomi the Nature Nerd

Naomi knows more than I could adequately or compentently tell you about nature, phenology, native plants, and much more.  So check out her blog from the link above or from my blog roll at the bottom.
