Hello, I bought this young thornless key lime for half off. I am curious if I should prune it and at what time it may be best to do if so. I am in zone 6b. Thank you in advance.

Someone on marketplace is giving away a 2 foot pipe made of clay that was underground for a while. Was curious if it could hypothetically be turned into a DIY forge. There is also a 90 degree angle.
