Start Your Own Avocado Plant
The next time you make guacamole, take the avocado pit (often called the stone) and push the flat end into a six-inch pot of moist, multi-purpose soil. Leave the pointy end exposed.
Make sure to keep the plant at about 65° F until the first leaf shoots appear. Aftet that, it likes normal room temperatures with slightly cooler temperatures (60° F) in winter.
To encourage upward growth, pinch off new buds when they appear below the top leaves on the plant stalk. With proper care, in three years your Avocado will grow to an elegant, large-leaved houseplant about 3 feet tall.
