Hi there,
This is my first year gardening at all. I bought some lantana, coleus, begonia and creeping jenny for my front urns. Before I got them planted, my son tripped and fell on one of the coleus and broke it. I cut it back and planted it anyway, but it doesn't seem to have survived. The nursery was also sold out of that variety when I went back.

So I got a couple more plants, but now the spacing is off. I'm wondering if I will destroy the original plants in there if I try to shift them around when I add the new ones? I don't want to hurt them but I would like the appearance to be balanced.

Thank you!
