This year I planted 100 osage seeds in small pots. I think I had about 80% germination with about 75% overall survival until the first trans potting. I purposely used a variety of gorwing methods to see what worked best. I planted the seeds in late fubuary and my tallest plants right now are about 4 ft tall with about 1/2" trunk my smallest are about 6" with about 1/8" trunks. Transplanting to 10 gallon pots right after they got a few leaves seemed to make the biggest difference, the ones I gradually moved up in pot size are about 1/3 the size of the ones I put immediately in large pots. Just a standard tree fertilizer, well drained soil about 50% dirt and 50% compost gave me the best results. Now I have to find a place to plant them, I think I will bonsai the majority. I think I am down to about 30 plants now, many I culled just because I didn't like the way they were growing or they attracted bugs.
