So I am new to the whole Bonsai Tree growing. Got my hands on some Japanese Black Pine and planted them about 3-4 weeks ago with no hopes of success as I suck at gardening. I followed the soaking process and planted a total of 9 seeds about 1" apart. Boom after week one I had 2 sprouts. These guys are now over 2" all and seem to be growing well. The tallest one has a new bud starting to grow out of the center. I got curious about the other seeds since they have not shown any signs of growth. upon digging I found that a couple of them looked to be cracked open like a pistachio while the rest seemed to have enlarged and become a light brown. Also upon digging, I have found 2 round worms, translucent white in color with streaks of black which I assume is dirt they have ingested. they are probably 1/2 - 3/4 of a cm in length. Not near the plants but close to the open seeds. I am worried these are parasites and not tiny little earthworms. So far the 2 that are actually growing seem to be healthy and strong, but I would have for these worms to end up eating or causing harm to the roots and me not knowing about it.
Do I need to remove these worms or re-pot my plants into some new , fresh soil with some fertilizer beads? Any help or suggestions would be great.
