1. Thoroughly wash your avocado seed.
2. Secure toothpicks into the seed so that they sit out horizontally.
3. Suspend the seed with the heavy, flat side down over a glass of water. About 3cm of the seed should be sitting in water.
4. Place the seed out of direct sunlight and top up the water as needed.
5. In 2-6 weeks, roots and stem should start to sprout.
6. When the stem is 15 to 18cm long, cut it back to about 8cm in length.
7. When the stem has grown leaves again and the roots are thick, plant it in a pot with half the seed exposed.
8. Water the plant lightly and frequently, with an occasional deep soak. The soil should be moist but not saturated.
9. Make sure it's getting plenty of sunlight.
10. When the stem is 30cm long, cut it back to 15cm. This will encourage new shoots.
Now you should be well on your way to growing you own avocado tree. ::
