Yes! Carefully remove your avocado pit and wash it well - but don't remove the brown covering. Determine which end is the bottom - that's where the roots will grow. Poke the seed with three toothpicks and balance them over a glass of water so that just the bottom of the pit is submerged. Place the glass out of direct sunlight. Once the roots start to grow, things get exciting. When the seedling reaches 6 or 7 inches tall, cut the stem in half. Really. This will encourage more root growth! Your little baby tree will continue to grow and you'll soon see leaves and stronger roots. Then it's time to plant the tree into some soil. If you live in a tropical climate, you can plant your baby tree outside. If you live in an area that experiences winter each year, pot your tree and keep it indoors or in a greenhouse. Once it's established, you can start moving it outside during the warmer months.
