I see 2-3" pvc pipes sticking out of the ground
near every tree in landscaping and also in those huge
3 ft. tall plant containers.
what is the purpose of this pvc pipe?
I do not see an answer to your question, and I'm wanting to know the answer as well.
Could you repost your question on the "other side" where real gardening questions are asked?
It is my impression (I'm new on this forum) that this GALLERY
side is for photos?
