Chrystanthemums - when to cut back
Hello. I planted these crysanthemums last year and they have been amazing, continuing to flower throughout the mild winter. I read that I should cut them back after they finished flowering, but that hasn't happened yet! However, now they are beginning to look a bit woody in the middle and the clump is 'sagging' apart. I think I should trim them back, but could anyone advise by how much? Any other tips would be gratfeully received. They have been a great addition to the garden, so I'd like to make sure they stay healthy!
I've grown them a few times and they are great. Like you I have managed to overwinter some in the past, but I've not had success getting them to flower again the following year.
The ones I didn't cut back were too scraggy to be attractive and the ones I did cut back into the old wood just died..
Sorry, but not sure what the best plan is.
Hopefully someone else will.
There's an RHS article here that describes how to take root cuttings at this time of year or you could try semi-hardwood cuttings as they describe.
It's a different variety to yours, but the process is the same.
Wishing you luck!
