How to grow avocados from stones

The avocado is an evergreen tree native to Central and South America. It grows oval, dark-green and brown fruit that can be used in a number of dishes, including guacamole. Avocado trees require a warm climate but often are grown indoors where climate can be controlled. Start your own avocado plant from the pit or stone of an avocado. This can be a fun project for children, and the avocado can grow into a nice houseplant, as well.

Remove the stone from the centre of the avocado. Cut into the avocado along a centre line, working a knife around the hard pit.

Pull one half of the pulp away from the stone, using a knife as a lever.

Remove the stone from the other half of the avocado pulp.

Wash the stone carefully. Do not remove the tan layer that covers the stone.

Stick three toothpicks an equal distance apart around the centre of the stone.

Fill a small glass or glass jar with water.

Rest the stone on top of the glass, using the toothpicks as the foundation. Place the stone broad end down with at least 2.5cm (1 inch) of it in the water.

Place the jar holding the avocado in a sunny window. Roots should appear in two to six weeks.

Pour off and replenish the water weekly, keeping the water level halfway up the stone's surface.

Cut roots down to 7.5cm (3 inches) when they reach 15 to 18 cm (6 or 7 inches) long.

Transplant into a 25-to-30cm (10- to 12-inch) pot filled with rich, humus soil. Keep half of the stone in the water.
