Making the hinge is the key to controlling the direction of the fall. However you can’t over come gravity with a hinge and I had one tear off like it wasn’t even there once when I improperly calculated the direction it would fall.
Tree management has a lot of different variables. Commercial interest is different then landscaping. You need to know the variety of poplar and the expected age/size it might grow.
Poplar Populus (Salicaceae)
eastern cottonwood Populus deltoides
balsam poplar Populus balsamifera
bigtooth aspen Populus grandidentata
quaking aspen, trembling aspen, popple Populus tremuloides
I have seen tulip poplar trees get up to about 20 inches in diameter and 60-80 feet tall so you could have a long way to go.
