Lilac bacterial blight on a very young plant
I have reasons to believe that my korean lilac (Syringa meyeri ‘Palibin’) is suffering from lilac bacterial blight. the tree is planted in a protected place on my balcony into a 30x30x30 cm planter and so far it has grown well over the last 6 or 7 months.
I already did research about this disease and I know the affected parts should be carefully cut off, but here is the problem I am facing:
The lilac is a very young plant and specifically this variety is very slow growing and I read somewhere that if I cut any of the branches then it won't bloom blossoms the following year and of course I don't want that to happen.
The second problem is, even if I would cut the contaminated parts off this would mean in my case that I would have to cut the entire branches off leaving the tree with almost no leaves which will probably result in the death of my plant altogether.
So what can I do? Cutting is not really an option since the blight is all over the entire plant.
I would appreciate any advice which can lead to the cure to my lilac tree.
