The method in water worked for me better! My second successful sprout is about to grow at the moment 🥑🌱 I would use the seed from a bio avocado.

You can poke 3 sticks in it like I did it with my potatoe, or as you can see on the photo, I made a little construction from rubber bands so I don’t have to poke into them! :) make sure the bottle you use is always filled with water, so at least 1/3 of the seed is under water. A few complete waterchanges are great too, but you can mostly just fill it up a little bit :)

When it’s growing, put it on a warm sunny window, maybe south window, and check for humidity, it should not be too low! 🌱🥑💚 hope this helps 🤗 and once it has a good rooting system, pot it in a good soil
