It’s been over a month since I started to root my avocado seeds.  As you can see in the photo above, the roots for my more mature seed are about 4 to 5 inches long.  The stem has also begun to sprout and is just past the surface of the seed.  I’ve been noticing them drinking a lot more water, requiring a fresh bowl every couple of days.  It will still be a while before transplanting to a normal pot — at this rate, about another month or two.  Stay tuned.
