Avocado is usually not grown from a seed in commercial orchards. However, avocado can be easily grown as a houseplant from the seed. Growing an avocado plant in your home can be a lot of fun, but you need to be careful because growing a plant needs a lot of patience and a proper environment. To grow an avocado plant from the seed, first remove the pit from the center and wash it under cool, running water. Do not use soap or hot water. Wipe away the remaining fruit from the seed gently with your fingers. Then blot the seed dry on a paper towel.
Push three toothpicks into the thickest part of the pit carefully, about ½” deep. Suspend the seed over a glass filled with water. Always keep an eye on the level of the water covering the base of the pit. It should be immersed in about an-inch deep water. In case the water is below the required level, carefully refill the glass without splashing any water.
The glass should be then placed on a bright windowsill. The pit will split open in about three to six weeks and a stem will sprout from the top. The roots will grow from the base. After the stem grows to a height of five to six inches, pinch out the top set of leaves and wait for another two to three weeks until new leaves and roots appear. Now take the young sapling, stem and roots, out of the glass and place it in a large flowerpot, filled with enriched soil. The flowerpot should be kept in a place that receives ample sunlight.
