A grafted plant consist of two parts, stock and scion. The stock is raised in most cases by sowing a seed and when it is about 3-6 months old, it is grafted using a scion material from the selected mother plant.
While planting care should be taken not to bury the union or the grafted joint in the soil. if you see any sprouts coming from the stock they should be nipped off while they are tiny or if they are allowed to grow unnoticed or by neglect they will grow faster than the scion and eventually the scion will die.
Remove the tape (plastic) from the graft before planting (if not already removed by the nursery). The new growth (scion) is very delicate so handle the plant with care. If the tape (plastic) is left on for too long (several months), the tape (plastic) may restrict growth in the grafted area.
The goal of grafting fruit trees is typically to create plants that are identical to the parent plant by combining part of the parent plant (scion) with the rootstock. A successful graft means that the two parts of the union begin growing together as a new plant.
