Bird House Gourds need over 100 days. You can start indoors and if you transplant carefully, these will need room to grow for support. They will make a nice arbor. This Heirloom garden seed will give you tons of fun crafts for the fall and winter. To our farmers market friends, you must add this to your list of fall stuff. The only way people can get these is from farm to fork, beyond organic, folks like us. Happy growing!!!
