Tulip trees are not a tree you want in a busy pedestrian township like Neutral Bay. Tulip trees are meant to be in parks it’s a big no no planting them next to car parking, buildings, pedestrian walkways due to the sappy leaves and brittle branches. And Military Rd can be very windy and they have shallow roots and could topple over and kill someone.

SIMPLY PLANT MAGNOLIA OR WATER GUM!!!”
