Avocado trees are native to Mexico and Central America, and grow in warm, humid environments. In the UK, it is possible to grow avocados from seed, starting with a supermarket fruit, but do be aware of the conditions that they need to grow happily.
A few sheltered places, especially in cities, offer microclimates that can support an avocado tree outside, but for the majority of us, they make fun, tropical houseplants that will last a few years before starting the process all over again.
Below is a step-by-step guide to producing the perfect crop.

So, to grow a plant, carefully extract the seed from the fruit. You now need to decide whether to grow the seed hydroponically (in water) or traditionally, in soil. Both methods require the flatter, broader end of the seed to point down, as this is where roots will emerge long before any shoots.
