how to graft hibiscus plant
Identify the root stock, the hibiscus that will be planted in the ground, and the scion, the hibiscus cutting that will be grafted onto the root stock.
Select a healthy stem on the root stock that is about the same thickness of your scion cutting. Cut it back to the ground until there are only about 4-6 inches of it above ground.
Cut the root stock with a slanted upward cut so that the pointed edge of the cut rootstock is skyward and the total length of the cut is about 2 inches.
Cut the scion in the opposite way so that it mirrors the cut you made in the root stock; cut it downward so that the pointed tip of the cut scion will point towards the ground and the total length of the cut is the same as the one you made on the root stock.
