How to Graft a Branch on a Fig Tree

Select a healthy, mature fig tree to use as the scion donor. Scions are the segments used for growing the upper portion of the fig tree, while rootstocks provide the support system that nourishes the foliage and fruiting vegetation. Select scion branches that measure between 1 and 2 inches in diameter. Cut the scion sections in lengths that contain three leaf buds. Snip the upper ends of the scions off at an angle about 1/4 inches above the top bud. Cut two sides of bottom portions of the donor branches to create a blunt wedge on each that measures about 1 1/2 inches long.

Cut the trunk of the rootstock tree within 4 to 6 feet of the ground. Make a vertical cleft in the top of the cut trunk that measures about 1 1/2 inches deep. Insert the tip of a screwdriver into the cleft to hold the opening apart. Insert one scion on each side of the open cleft, pressing the tips of the scions firmly into the openings.

Apply grafting compound to the cleft. Remove the screwdriver carefully to avoid disturbing the scion placement. Apply additional grafting compound around the exterior sections of the graft union, completely covering the cleft opening.

Hammer a tree brace into the ground next to the fig tree roots. Tie the trunk of the rootstock to the support brace, slightly below the graft union. Tie the upper part of the scion to the tree brace after new growth emerges. Doing so helps provide additional support to the grafted area during adverse weather conditions.
