Avocado trees, prized for their fruits, thrive in tropical, subtropical and some temperate climates. Ordinarily, avocado trees are propagated by cuttings of mature, thriving plants, but growing an avocado tree by seed can be accomplished. With proper care of the seed, a tree can mature in as long as a decade, although homegrown avocado trees rarely fruit.
Slice or shave a thin layer of the fleshy pit from the top and the bottom. This allows for the seed to germinate more quickly.
Dig approximately 1 foot into the ground in the selected planting site.
Fill the hole with a mixture of sand, potting soil and manure. Mix these soil amendments thoroughly in the hole with your shovel.
Sow the avocado seed directly into the soil, approximately 3 inches deep.
Water the seed once a week, giving it approximately 2 gallons of water per watering.
