Why did all my petunias in my planters die so quickly?
I have many planters on my front patio, which gets full morning sun til 1 pm, then house shade afterward. They have mostly foliage like yellow and purple sweet potato vine, variegated English ivy, a dark, almost black coleus; and then I add flowering annuals.
This year I put petunias in them, with the foliage plants. The petunias died with a bang. Maybe it was shock, I took them from a greenhouse environment, then into these large planters. I kept the planters in the shade for a week, then moved them onto the patio. Dead within days. These were quart sized petunias, not little rootbound six packs. I was thinking it was too much sun. Everything else in them is flourishing, and those also came from the same greenhouse. The sweet potato vine has doubled in size. The coleus also looks great. I water whenever the pots get dry, which is usually every other day.
But then I realized the ones on the back deck had also died, though they took longer to die: and those have dappled shade most of the day.
What can I replace them with, that can tolerate full morning sun? I bought an assortment of things with the right color, but then I decide to ask here first.
Coleus? Impatiens? Snapdragons? Geraniums? Thanks!
