Tulip Tree Design Tips:
Tulip tree grows fast, so it is useful as a shade tree. Since it grows so fast and tall, make sure you choose a location that will hold such a large tree.
Be careful planting these near cars (or anywhere else that you would not like sticky honeydew to land on) as tulip trees are prone to aphids.
Also plan to rake up flower litter.
Growing Tips:
Prefers acidic, moist, well drained soil. Salt intolerant. As the tree matures and establishes its root system, it can become somewhat drought tolerant, though some of the interior leaves may drop.
Tulip tree should be planted in the Spring, as it is very sensitive to being planted in the fall. If you are planting a tree that is ball and burlap, you should make sure it is watered regularly for the first 3 years or more to properly establish the roots.
