Newt I just went out and purchased large bags of potting mix. Poured it all along my kitchen window on the east side. Then broke the soil loose on bottom of each plant and planted them into the ground.Then watered and mulched. I do not have the mulch up close to the plants. I fertilized with Osmocote. One week later used the bloom booster hoping to get more blooms.
Water daily or every other day.
I have several of these on my sun porch.Their blooming every now and then. But nice an green. I have some others that I thought were dead, when I returned three days later. I gave them water and they came alive.
