Unlike most vegetables we see at the market, avocados are actually a fruit grown on trees. Avocado trees can be used for landscaping, as a decorative houseplant or to produce fruit several years down the line. Save your next avocado pit to grow an avocado tree for your yard or your house. You may not see fruit on your tree for over a decade, but you will have a homegrown leafy addition to your garden or house.
Rinse your avocado pit in cool water and insert four toothpicks into the top half of the pit until they jut out horizontally.
Fill a drinking glass with water and rest the toothpicks on the glass rim with the heavy side of the avocado pit facing down. Make sure 1 inch of the seed is submerged.
Place the glass in a warm location away from direct sunlight. Replenish or change the water at least every two weeks.
Trim back the stem to 3 or 4 inches when it reaches a height of 7 inches. Watch for new leaf growth. When your plant has produced leaves again, transplant it to a 10- to 12-inch diameter pot filled with potting soil. Place the seed on firmed soil and add more soil around the seed until it is half exposed.
Keep the soil moist with frequent watering and place your avocado plant in a sunny spot in the house or garden. In order for your avocado tree to produce fruit in the future, it will need plenty of direct sunlight.
Annually feed your avocado tree with a zinc fertilizer containing a balance of nitrogen, phosphorous and potassium.
