This winter the cuttings did not do well, but most survived and finally started filling out when I replanted them outside. But I notice now that the leaves are more yellow than they ever used to be. Anyone have any ideas why? Do you think it's a lack of fertilizer? I did put some plant tone in the pot about a week ago. The first photo was taken this morning, the second one was a pot from 2 summers ago, but the exact same mother plant.
