Want to give the kids a fun science project and gain a new, free indoor plant? Next time you serve up avocado at a meal, keep the seed (organic is best, as it won’t have been treated with chemicals or growth inhibitants).
Wash and dry the seed, removing any skin. Locate the bottom of the seed, noting the seam where new growth will appear. Poke 3-4 toothpicks into the seed, avoiding the seam, then place it into a jar and add water to cover the lower third. Place in a sunny spot, and after several weeks you should have a baby avocado tree to care for.
