I have planted a Norfolk Island Pine from a pot into the ground (Central Florida near St. Johns River). It has grown from a spindly plant to a healthy tree about 20 feet high. It was knocked over a few years ago by a hurricane, but upon setting it upright, it has continued to grow. My question: May I trim the bottom branches which are close to the ground so that one may eventually walk and see under the tree?
I'd disagree there - retaining the low branches will help thicken up the trunk and make it sturdier and stronger. This could be important while it is still re-establishing a good root system after the hurricane damage. Cutting them off won't encourage new growth in the crown at all.
