Michaelmas daisies and chrysanthemum

Sorry - flowered for the first time last year!

Cut them back so the nutrients from the roots stay at a lower level and keeps them strong.

We have Chrysanthemums that have flowered for the past 4 years. DH just dead heads rather than prune.
Move the pot to a sheltered spot (if you can) and unless we have a very cold spell yours should be fine.

They are perrenial. I had these in my last garden and just trimmed them lightly when the flowers had gone over. They do tend to be a bit thuggy, which is why I haven’t introduced them to my present garden, but they grow wild around here so I do get to enjoy them on walks!

Sorry. The above relates to Michaelmas daisies.

Thanks for all the advice - I will give them a little trim - is it OK to do it now, or have I missed the boat?

It doesn't really matter, Luckygirl. I have some I didn't have time to cut back in the autumn so I've left them. I will now wait for another month or until I can see some new growth at the base just in case we get some really harsh weather. I suspect our frosts are harder than yours.

Trimming them now won't hurt them.

Thanks merlot - all I have to do now is remember all this stuff people are kindly telling me!
