I just repotted these into a bonsai pine mix in 4inch platter pots, good drainage, they started inside, I let them grow outside most the spring/summer except rainy days where I brought them inside. I had a few more but they weren't even close to as developed as these so I felt these were growing pretty well. I only water once a weekish/as needed. I am cautious to not over water. maybe they need food? thru get plenty of sun. I move them twice daily into sunny areas of my house. I live in upper Michigan so winter they won't be outside...
