This is what I would do. If you keep these in temperature regulated area...it can be done before spring, roots still grow (if not too cold) giving it a good start come spring.
Next time, better to plant them in smaller pots (styrofoam cups work well with bottom holes) then placed in a common tub (or tray) filled with same medium (i.e. turface). You can just pull the entire cup when you want to plant them in their "individual" grow pot later.
I've read that some grower cut the tap roots ASAP while the seed is still germinating with the seed still attached and providing nutrients to the sprout. This is to encourage even and spreading (radial) root system rather than a single deep taproot. I can envision this working.
So I just decided to pot a few up about 3 days ago. Here is a tray of 17 of em. So far so good and more coming up all the time. Very near to 100% germination. Not bad for just under 2 weeks from collection. I also just went and collected another batch of seeds.
The thing that made me decide to do it is that we are entering our second growing season. It is kind of like spring right now with the monsoon rain. Soon we will be down in the 80's until October or so.
Love to see anything about the Texas Ebony. It's the only tropical I have. Does well in the office in the winter. West side of house. Very bright window. In the summer it laughs at 105 degrees. Truelly tuff great tree. I don't cut the thorns off. I think it deserves them. It loves too much water and does not hate you for drying out.
