Bonsai Nut
Nuttier than your average Nut
Am with you... that's why I start the trading seeds thread. I don't see myself having a few hundreds of pine seedlings to care for.
If you are lucky, assume 75-80% germination rate.
Then assume the same rate of survival for the first root cutting.
Then you will want to cull based on strength / growth of the seedlings.
At end of Year 1, I am hoping for 25% healthy strong plants to take to Year 2.
