Hey nice experiment! It looks like your little avocado tree is growing up nicely. I'm sure some outdoor growing next summer will do wonders! I tried the same thing once but grew impatient and destroyed the emerging shoot. Patience is definitely the first lesson as a gardener! Good luck!P.S. This works for mangoes too!
Oh yeah...this is Chris...the TA from Hort 1130
hey thanks, chris! yeah i tried to sprout a few mango pits last winter, but had no success... i was eating more avocados anyway.
