From what (little) I've read, the flowering without fruiting is not uncommon but I haven't read of reason. It will be intersting to see the variability of seed-sown plants. Some say to start the trees out with a little nitrogen in the spring but then switch over to phosphorus only (no nitrogen) as the season warms up. I'd rather not use anything except that for this year, they'll be growing in potting soil. I will add some compost but maybe not a lot. I wonder what's used in China/Tibet on the pics of groves that I've seen.
