Will several mature pine cones placed in the bottom of a large pot,
underneath the dirt (to make it lighter to move) produce anything that
might harm the plant?

Would it cause the soil to become acid, alkaline, or neither?

Thanks in advance.


Why would you want to put them in the put to begin with?
