I can't tell you how many times I have tried to sprout an avocado seed.
I finally learned the secret - I was giving up too soon!
It takes months, not weeks, for the seed to sprout a root and then a plant.
After watching this youtube video I vowed to not give up this time.
I wish I knew when I had started this seed. It was either late June or early July I think.
And here we are in September with a little plant started.
Now to research what to do next...
