I do plan to offer seedlings at some point. The problem is that the
seedlings I have are growing densely packed in an area beneath the
mother tree, and there is no way to dig one without causing damage to
others. The only effective plan I've come up with would be to dig a
pit next to the area and then use water pressure to erode the side
wall into their area and release them en masse. I cannot very well
sell one tree today and another tomorrow and two next week that way,
so I think I need to have a pre-sale, take all the orders and collect
all the monies, then close the sale and dig the pit, free the required
number of seedlings and ship them out to the buyers. Its just that
now, with the heat and the mosquitos, its too much of an undertaking
for me. If all goes well, I would expect to do be able that next
spring, but no promises. Whether you wait for that, or try your luck
with seeds now, or both or neither, you decide, I don't know what to
suggest for you.
About the seedling in the photo, I was telling my friend that I should
sell the seedlings, but the problem was getting them out of the ground
because of the taproot. So he grasped one by the base of the stem
and snapped it out of the ground in order to see the taproot. So he
proved it was possible to extricate one without damaging others, but
the damage to the one was likely substantial. The taproot itself was
intact, but the network of finer roothairs was left behind. That
plant may have recovered, but I would not sell trees in that
condition.
So you know I am not kidding about densely packed, there is a photo I took last year:
