I've had two parsley plants, a Corsican mint and a sage plant in the same bed start to wilt, then within two or three days they're dead. The same bed also contains majoram, rosemary, thyme and Aptenia cordifolia (the hybrid Red Apple, as far as I know) and they are all fine. The bed is L-shaped - c.100cm by 150cm. It started at the short end and has moved around the corner (bypassing the abovementioned plants).
I've ruled out over/under-watering. I checked the roots of the sage and they seemed fine - they weren't rotted or had anything on there that I could see with the naked eye. I assume it's a soil problem but I'm stuck as to how I find out what, and how to stop it spreading. (Worst case it gets to my treasured asparagus, the only survivor of my first attempt to grow from seed).
hi. not sure why that's happening to your herbs but care to experiment starting new ones in individual containers with fresh potting mix? if they fare better, then you could be more certain it's a soil issue. good luck!
