每日吃瓜

I recently planted some Japanese Black Pine seeds in a covered seed starter container. Five have sprouted, and the first one grew to where it was almost to the top of the container. I re-potted it in seed starter soil and it was fine for 4 days. This morning, it's over on its side. Too much water? Not enough water?

Once you've planted, you don't repot for a year at least.
