Experiments in Growing Seedling Mimosa Trees in the Greenhouse – Part 1
My mimosa tree seeds have sprouted quite nicely AND the seeds I planted in pots have grown to the point of having their first set of true leaves. Statistically, 5 out of 5 of the nicked seeds planted in pots are growing, but only 1 of 2 of the un-nicked seeds. Since the un-nicked seeds I left in the bowl of water still haven’t plumped up or sprouted roots, I found it surprising that even one was growing!
To read how I started my seed sprouting for these tree seeds, go to part 1 of Experiments in How to Sprout Mimosa Tree Seeds. I did take the pots out of the warming cupboard and removed the plastic trash bag after 3 days, at which point I was worried about mold. I could see a few hopeful looking bumps in the soil for about half of the pots when I did this. I put them in the greenhouse, under grow lights, and kept the soil moist.

I haven’t decided what to do with the other seeds in the bowls of water yet, but I will have to soon. The nicked seeds have all got pretty long, curling roots at this time. It will be another experiment to see if they can still be transplanted successfully. Meanwhile, it looks like I might have 6 mimosa tree starts to play with. 🙂
