  • This Taught me alot while looking out my window i saw the yellow leaves and just thought: i know why the fall off but why dot hey change color. Thankyou for this! this is great educational video!

  • I am James Davey. I have gotten tours of the Davey Headquarters in the past. My distant relative is John Davey who started this company and is buried in Standing Rock cemetery in Kent. I am the last decent of the Davey family with the Davey name. That is my name on all the stuff in these vids. I wonder if Janis Hittle is still working at Davey in Kent (hopefully I spelled her name right), she used to give me tours of the place. You can see my name on all my vids. Nice work on these vids!!!

  • the foilage on roses are red because of the Anthocyanins, and it protects the new growth on roses from UV rays, later the red color will fade and be green.

  • Great educational video!
