Snipper
Seed

Exactly Six Saturday's ago I planted a couple Rocky Mountain Pine seeds and some Royal Poinciana seeds.
The day before I potted them, I placed them all in warm water and these are the ones that sank to the bottom of a small custard cup. These are the ones I planted.
Today, they seem to be doing quite well. They seem to love the window spot, where they get a few hours of direct sunlight a day. They've been in the same spot since I first potted.
The two pines sprouted first about 2 weeks after planting. The poinciana popped out at about 3 and a half weeks.
The pines grew really fast and have now seemed to stop growing upward are and now spreading out their needles. They both seem to be growing on an angle for some reason, so I turned them to encourage them to grow toward the light in the window.
The poinciana has been growing a lot faster now since popping out of the ground and it's quite impressive already. It's little leaves fold up at night and then spread out in the daytime. Pretty cool! It also acts like a satellite dish, for when I turn it on a weekly basis to balance out the sunlight, the leaves and branches will slowly turn toward the sun. I rotate the poinciana once a week and it has turned toward the sun every week.
Anyway, I'm a beginner. Any advice? Should I just leave them be and just keep doing what I'm doing?
As for the pines, should I trim the tap roots and replant them as cuttings? Or just let them keep going as is? Also, should I do anything more about the angled growth of the pines? Or just let'em keep going?
Thanks.
