| I water all my houseplants once/wk. The leaves on all my calendula plants yellow and wilt, one by one. I cut them off, but then the next week has one or two others doing the same thing. What am I doing wrong? |
| In my experience, calendula is not a terribly long lived plant, so it may be that the plant is signalling a decline. It is also possible that you are over or underwatering, or that there is an insect infestation. You might check the undersides of the leaves and the stems for signs of any activity. |
