When to plant my avocado seed?
I've been growing an avocado seed in a glass of water for months now (I'm in Newfoundland, Canada, so growing outside isn't an option for this one and light has been limited). I'm worried this guy is about to break in half, but I've read you should plant when the sprout is several inches high. The sprout is trying to fight his way up, and splitting the seed, and the root is longer than my finger now. I'm also a bit worried about the growth around the sprout that you can see in the picture. Should I plant it? Cover it all the way? I'm new at this. Thanks!
