Hi there, I'm located right smack on the border of zones 6 and 7. And I have two questions. 1. Gerbera Daisies. I have two plants that each share a pot with some creeping jenny. They are situated very close to one another (on either side of the stairs that lead up to my porch) and get an almost-equal amount of sun). One plant is doing beautifully. The other started out doing very well but about three weeks ago the petals started to turn a rusty brown color (including the new heads) and one by one they died off. The leaves still look very healthy. If you spread apart the leaves of the nonflowering plant, you'll see a bunch of tiny new heads that have a white gauze (it almost looks like a mold) on their stalks. And today I found a
small worm/caterpillar thing (about 1 cm) a cutworm tucked down there as well, so I plucked it out.
The blooming plant only has one or two new heads down among its leaves and they seem to be growing to full size. How can I get the ones in my nonflowering plant to start growing again? Did removing the worm solve the problem, or is it something else?
2. Hydrangeas. I have a recently planted hydrangea plant that sprouted pretty pink blossoms about a month ago and now they're turning a funky muddy pistachio color. The blooms are drooping and looking dirty. I've been watering the plant regularly and even added acid to soil prior to planting. The hydrangea in front of the neighbor's house, which is literally feet away from mine, has gorgeous, thriving blue blooms and it's been abandoned for over a year. What am I doing wrong?
