Avocado Plant ~ Take the avocado pit and push the flat end into a six-inch pot of moist, multi-purpose soil. Leave the pointy end exposed. Keep the plant at about 65° F until the first leaf shoots appear. Aftet that, it likes normal room temperatures. 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.
