Norfolk Pine Indoors: Size Control via Root Pruning and Pinching

In a pot, it grows 10–12 ft; in ground, 80–100 ft. To keep it manageable: stop repotting at ⅔ desired size (max 14-inch pot). Every 3 years, remove, shave 2 inches off rootball, repot in same pot. Pinch back ½–⅔ of soft new spring growth to slow height increase. Without this, you'll need to move it to Florida in ~10 years.
