Avocados have grown in popularity over the past few years and they are used in a variety of dishes, dips and even beauty products. If you're thinking you'll be able to cut out your avocado budget by sowing an avocado seed, however, you should think again. While avocado seeds are easy to sow, it takes a tree grown from seed around 20 years to produce avocados, and only if it is grown in the tropics. You can, however, sow avocado seeds indoors. You won't harvest any avocados, but you'll have an attractive houseplant for two or three years before the fast-growing tree outgrows your home.
Remove the avocado pit from the fruit. Rinse it thoroughly to remove any clinging flesh.
Peel off the avocado's seed coat. Then slice a tiny sliver off of the top and the bottom of the pit.
Stick three toothpicks into the avocado pit at even intervals along its equator.
Place a small piece of charcoal in the bottom of a glass. Fill the glass to the brim with water. Place the avocado in the glass so that the toothpicks rest on the lip. Submerge the wide bottom of the avocado in water.
Wait until roots begin to grow out of the bottom of the avocado. This may take anywhere from 2 to 6 weeks. While you wait, change the water in the glass once a week. If the avocado does not sprout within 2 to 3 months, compost it and try steps 1 through 3 again.
Fill a 5 inch porous clay pot with gardening soil.
Remove the avocado pit from the water when the roots reach around 1 inch long.
Sow the avocado in the soil. Dig a hole that is slightly larger than the avocado and set it carefully inside, taking care not to damage its roots. The avocado should sit so that its tip is just slightly above the surface of the soil.
Water the avocado thoroughly.
