My climbing rose(2years old) has totally collapsed over night! It is in a container but is well tended,but now looks like it hasn't been!It has a rambler next door to it in a similar container which receives the same care and is totally fine!!
Name: Suzanne/Sue Sebastopol, CA (Zone 9a) Sunset Zone 15
What kind of drainage does the container have? My guess it the roots filled in and plugged the drainage holes so water can no longer drain out, leading to root rot. It's happened to me several times with various plants.
Many thanks for your reply Sue! The container has actually had most of the bottom removed and settled on to the garden soil! I originally did this just raise it up! I know the weather has been hot here but lack of water is usually indicated by a slow wilt not the total collapse that's happened! I am wonderful if vine weevils might be the issue!
