When growing avocado trees at home, bear in mind that they can take anywhere from five to 13 years to bear fruit. Begin the process by growing an avocado plant from a pit in a glass of water, and then transplant to a pot and eventually outdoors.
Remove the pit, rinse it well and allow it to dry. Push three or four toothpicks into the widest parts of the seed, and suspend it over a glass of water with the pointy end up. About an inch of the pit should be submerged in water. Place the glass in a warm place.
Seeds take two to six weeks to sprout. When the stem reaches 6 inches, trim it to half its length. When the stem grows more leaves, move the seedling to a pot with sandy loosely packed soil. Plant the seedling with the roots facing down and the top half of the pit above the soil.
Water the plant lightly and frequently, and keep it in a sunny place. Pinch back the newest top leaves every time the plant grows about another 6 inches. In areas with warm climates, gradually acclimate plant to outdoor life by bringing it outside for a while each day for two weeks preceding transplantation. Plant in a hole 3 feet wide by 3 feet deep. The area should have well-drained soil and receive lots of indirect sunlight.
