How can I successfully grow an avocado tree in my house?

To successfully grow an avocado tree in your house, you will need to start by germinating an avocado seed in water. Once roots and a stem have developed, plant the seed in a pot with well-draining soil. Place the pot in a sunny spot and water it regularly, making sure the soil is moist but not waterlogged. Avocado trees also benefit from occasional fertilization and pruning to encourage growth.
