I’ve been asked multiple times to give a step-by-step guide to growing an avocado tree from a seed. Well, here it is.
Wash the seed to remove any avocado. Stick 3 toothpicks into the side of the avocado seed and fill a tall glass of water close to the top. Put the seed into the water with the pointy end facing up. Place the glass and seed on a windowsill which doesn’t receive direct sunlight but is well lit. Make sure you keep the water covering the bottom part of the seed.
You’ll see roots first at the bottom and then the stem sprouting from the top in 2-6 weeks.
When the avocado tree is about 15cm tall, plant out into a pot or the garden.
