The four-flap graft or banana graft is used in top-working small caliper trees.

The bark is peeled away from the rootstock in four flaps.

It is used on pecans.

Both the scion and the rootstock should be of equal diameter. The scion is dormant, while the bark on the rootstock must be slipping.

Illustration showing three steps involved to prepare rootstock for a four-flap graft. In step one, a rootstock with it's top removed has the bark at the top end split into four flaps. In the second step the four flaps are pulled down, with a rubber band wrapped around the stalk below them. In step three, the stalk above where the bark flaps meet is removed.

The flaps of the rootstock are pulled over the stripped scion and held in place with a rubber band.

In step two the rubber band is pulled upward to secure the scion within the four flaps. In step three the graft is now wrapped with tape to further secure and protect the graft.

The entire graft is covered with foil to prevent over heating and a poly bag to prevent desiccation.
