Why You Should Not Plant Pin Oak!:
The tree grows into a gigantic tree and you need plenty of yard room - at least 600 sq.ft. Pin oak needs acid soil and "wet" feet so soil test first. Its leaves will turn yellow and decline in vigor if planted on alkaline soils. The tree can also be a maintenance problem because of a tendency to grow limbs low down the trunk.
Pin oak is actually a very beautiful tree and well worth planting on a proper site with plenty of room.
