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.
Liriodendron tulipifera prefers acidic, moist, well-drained soil, and is 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.
