This is my first message here. I live in France. I'm not an expert in gardening.
I have a few cannas in my garden. I got some of them from gifts, or I grew them from seeds.
I'm very much concerned about the canna viruses. I'm trying to keep my cannas healthy. I think i will stop getting new cannas in order to keep the ones i own safe.
I have a few big cannas (I think they are canna 'Robert Kemp') which are beautiful. They are planted en-mass. A few years ago it was 3 little pieces of rhizomes I found in my garden, and they have grown quickly. At this time of the year, they are just starting to flower.
Yesterday I noticed that one side of the "bunch" (is it th correct word ?) had strange leaves. I hope one of the plants did not get a virus.
What should I do ? Remove this part of the cannas, digging out the rhizomes (and hope the other plants didn't get the disease yet), or wait to confirm they are heathy or sick ? I know the first leaves can sometimes be ugly on cannas.
The other plants in these canna R.Kemp seem alright to me.
I collected a lot of seeds from this canna last year, so I can grow a few of them to replace diseased plants... but I will have to wait for a year or two until they reach the full height.
