for those grrown in a pot 1 plant is advisable. for outside growth the 3-4 plant ina "hole" isfine.
I would seporate the plant & pote 1 per pot the others should be potted up for groowth in the ground. in each case there will be a delay befor new growth starts.

Thanks yiorges... I have transplanted them one seedling per pot, they just look so tiny and lonely in their new homes. Almost all of them are still standing up, a few had already fell over in the peat pot with the top leaves still up toward the light...

I am curious on these... should I remove the seed leaves, and plant it down to there? The stem is darker purple on the ones that fell until the bend and green leaves turning back up to the light, just wondering if that could be under the soil?

These guys look so itty bitty all alone in their new pots, but - apparently they are gonna spread and grow to fill it up eventually.. Thanks!
