Lychee and Longan trees are relatives, so I expect that they will germinate the same way. Their seeds are very similar as well. I have germinated many lychee seeds before. They usually take a week or a bit more to germinate.
You can see that the one of the longan seed has started to crack and open already. That is where the root and the stem of the tree will grow from.
It is my first time germinating longan and tamarind seeds. I wonder if germinating the tamarind seeds will be different than the other ones.
Thank you so much for watching! I will keep you updated with the seeds and seedlings. :)
