Avocado seeds turning black

Avocado    None Given

My avocados are exported from the US. They are very delicious so I decided to plant my own trees. I used the toothpick in water cup method indoors and put them next to a sunny window. A few days down the road they started to turn black and wrinkled but still sprouted. What is this black color? Is it normal? Will the tree produce fruit that is safe to eat?

It looks like the seed might have a fungus and is rotting away. When you plant it, the seed might rot and kill the plant. I'd be inclined to get a few more avocados and sprout several in order to get ones which are healthy and not blackened. You can always plant the ones which are turning black and see what happens but given the time taken to grow fruit, it may be best to make sure you start off with healthy seeds. In terms of fruit, you are going to have to wait a few years before the plants begin to produce. Anywhere between 7 and 15 years for a seed grown tree. If you want fruit sooner you may consider purchasing a grafted tree while your own plants grow.

Yes but the fungus may spread and kill the sprout. Unfortunately - yes it will take many years to see fruit

I have not had a high rate of success in sprouting avocados. More of them ended up looking black and rotting, or simply never germinating. I finally found an avocado pit with had already had begun to sprout. Although it was slightly dried out, it has finally begun to germinate! So don't give up, it is possible to germinate an avocado. My suggestions are to try an extremely ripe avocado, and use pits that have signs of germination. Unfortunately, it will take several years for the tree to be capable of producing of fruit. Also, indoor grown fruit trees can sometimes have problems with producing fruit.
Good luck!
