ik that when feeding your tort, you should make sure that they are fertilizer free.Which i understand why this may be a problem for you tort. I live in Wisconsin, so there are only 6-8 months out of the year that the weather conditions would be suitable for my tort to be outside. My dad fertilizes our yard, and my question is should i never alow my tort on the lawn, or just not right after the lawn is fertilized, either way i wanna make sure he can get some natural sunlight, but i might have to take him to a different location. thanks, cody
