The tree can be kept as a house plant, or it can be transplanted outdoors if you live in an area with warm winters. Called a seedling because it is grown from a seed, the tree can actually bear fruit. Commercially grown avocado trees are the result of the grafting of a certain kind of avocado tree onto root stock. The fruits of a seedling may not be as large as commercially grown avocados.
Seedlings generally begin to blossom and produce fruit after three to five years.
A clean avocado seed. Wash all clinging pulp from the seed, but allow the brown protective coating to remain. A wide-mouthed glass jar. Mayonnaise jars are a good size. Three wooden or plastic toothpicks.
