Dahlia tubers care

Id also love to know what you mean by covering with non porous material...do you mean the tubers, the stem, or around the entire planting/pot? What do you use for the material, and where? This will be my first year growing, from small clumps and started seeds. Thank you!

What do you mean by non porous material. The tubers are under the ground. Do you mean the stem? Thank you!!
