1. Grafting a Pecan Tree

2. In pecan trees, the varieties with high-quality nuts often have weak roots. Varieties with strong roots have poor- quality nuts. To get high-quality nuts on strong roots, pecan farmers insert a scion from a high-quality nut variety into a strong rootstock variety. This procedure is called grafting.
graft: a shoot or twig inserted into a slit on the trunk or stem of a living plant
rootstock: a living plant into which another variety is grafted
scion: a young shoot or twig of a plant, cut for grafting

3. Step 1
From the top of the longer carrot, measure ½ inch (1.27 cm) and mark. With the plastic knife, cut to the mark. This is your rootstock.

4. Step 2
Stick the smaller carrot, the scion, into the slit of the rootstock.

5. Step 3
Use a thumbtack to secure the scion in the rootstock.

6. Step 4
Wrap tape around the rootstock up past the graft so it is covered.
