Yeah, Melissa, a clean paper towel or napkin would sure have been handy after making that first cut!
The second cut was much simpler having already re-potted. I just sliced the top off and dealt with the top. I didn't have to think about the base.
I re-potted another group of seedlings today, but haven't made any more cuts. I'll re-assess in a few weeks to see if any more "need" to be pruned, and maybe even make a couple experimental slices. The ones I already cut look to be healing nicely.
And Doris, seeing how you pruned back your large Adenium made me realize I need to do the same with my two large ones. It'll have to wait a while, though, as they both have just come into heavy bloom. But I know what the future holds!
