Hass avocados are a nutrient-dense fruit---yes, a fruit, not a vegetable---that has more than 20 vitamins and minerals and provides healthy mono- and polyunsaturated fats. Its creamy texture and delicate flavor make for wonderful sandwich spreads and guacamole dips, and it complements fish and chicken dishes. After using the avocado, do not throw out the seed, but use it to grow a gorgeous house plant that will eventually bear fruit. The fruit from this plant takes many years to produce and has a slightly different flavor than the regular Hass avocado, but the plant alone is worth the effort of growing.
Fill a glass with water to about 2 inches below the rim. Holding the avocado seed with the pointed side up, insert three toothpicks around the middle of the seed. Rest the toothpicks on the edge of the glass so the bottom half of the seed is in the water.
Place the glass in a warm area, such as a kitchen counter of windowsill in an east-facing window where it will not get bright direct sunlight all day. In about two to six weeks the seed will start to sprout roots and a stem.
Pinch back the stem to 3 inches after it has grown at least 6 inches tall. Keep it in a warm location for another few weeks until stem has leafed out again and the roots have grown thicker.
Plant the sprouted seed in a 10- to 12-inch container that has drainage holse and that has been filled with humus-rich soil.
Dig a hole in the center of the container that is the same depth as the height of the seed. Place the seed in the hole, leaving the top half of the seed exposed, and firm the soil around rest of the seed.
Water the newly planted seed well, until the water flows out of the bottom of the container. Water it every other day or so just to keep the soil moist, not soggy. A light watering is sufficient, and too much water can cause the leaves to turn yellow. If this happens, let the soil dry out completely for several days, then resume watering lightly every two to three days.
Grow the new plant in an area where it receives plenty of light for it to thrive and grow fuller, instead of becoming too leggy from inadequate lighting. Place the container in a south-facing windowsill or on a table in front of a large picture window. During spring and summer, when the weather is warmer, the plant can be set outside to receive adequate lighting.
Cut back the stem 6 inches after the stem has grown a foot. This will encourage new shoots to form as the plant grows, helping to create a more bushy plant.
