I got a pine tree grow kit around Christmas. I planted the seed and it has grown to about 4 inches and has stalled over the past month or so. It seems sturdy and is green with a brown 'trunk'. I repotted it around the same time it stopped growing. Is it in shock? Could the pot be too big? I didn't think that would matter since they grow outside in an even bigger area.

If this happened after it was repotted, it could simply be focusing on growing roots. As long as the plant looks healthy overall, I would not worry about it. It should start to grow again in a few weeks, particularly as the weather warms up.
