Wellington is correct.....I would just like to add...please make sure your neighbor/neighbors gardner does not apply pesticides/herbicides/fertilizer on or near that plant you will be offering as food to your tort....
Thanks! I never knew Magnolia was safe. I've been giving it to my Torts this week since I saw this thread - they love it!
Magnolias seem to be a tree that, at least in Northeast, flowers for just a couple weeks a year, so one can probably give them a lot of it during this time, as it wont be available the other 50 weeks of the year.
My group thanks you for the tip!
