Best time to move and divide plants?

Bill_and_Ben

I've got a number of plants I want to move and am wondering when if the best time to do this? They are

• Hemerocallis - three varieties, one to move and two to divide and replant.
• Gladioli
• Camassia
• Croscosmia
• Rose Silver Anniversary
• Rose Golden Showers
• Red hot poker

Usual time would be Autumn or spring this usually means soil is warm but weather rainy and cooler so plants cope better.
Day lilies pretty much anytime and gladoili are often lifted and stored over winter as they aren't  frost hardy don't know if that applies to camassia as well,

I'd agree - autumn is usually best, although many are fine, and sometimes better, in spring. it's just to avoid stress, but it also depends on where you live and the local climate. 
Camassias are tough. Need moist soil. They're bulbs though, so you can usually lift and separate them quite easily now, or later on. 
Crocosmias are tough too, like daylilies - no problem dividing them at almost any time of year.
Gladioli are usually lifted unless you live in a frost free area. 
Kniphofia will be fine in autumn, but you can also do them in spring if the climate's better then. Pretty easy and tough. 

I don't know anything about roses, but others will know. I'd expect autumn for those. Might depend on the pruning times though.

The best time to move any plant is autumn because the ground is still relatively warm and is also moist so roots can get settled quickly.  Roses will certainly be happier moving in autumn so they can establish themselves ready to support all the new foliage and flowers.

The only plants I wouldn't divide in autumn are hostas and ornamental grasses as they have a tendency to sulk and even die.  Much better done in spring.   I would also do late flowering plants such as heleniums, rudbeckias and Michaelmas daisies and the like in spring as they are busy flowering till quite late into autumn.

Many thanks K67, Fairygirl and Obelixx for all the really swift and very practical advice which is much appreciated. 

I'm in Cambridge (East Anglia) so usually cold winters (although less so in recent years) but dry in general. Although the reason I am now at my computer is that it is raining torrentially! The most and heaviest this year I think. We bought a bit of extra garden a few years ago and had it professionally landscaped. It costs a lot but we've been so appreciative of it this year especially as we've been out there at every opportunity. I'm still learning about gardening - hence the moving things around stage. I'm also compiling a spreadsheet of things I've got and what I need to do each month of the year so this is all really helpful - also for the hostas, rudbeckias and daisies as I have them too.

I see you all have your location next to your name - I will go and figure that out now as I can see that would help in responses. Thanks again.

Click on your name on the black bar then on the little purple arrow next to the head-and-shoulders, then you can add your location to your profile. It really helps to put people's comments and advice into context if you can see where they are.

Someone said yesterday they were having problems adding stuff to their profile, so there may be a glitch with it just now. You might have to sign out and back in too, after saving any settings you change 
If you have any problem, it can be flagged up to the mods tomorrow

I've been trying to add my location but get this error:



I've logged out and in and tried a few things but no luck so hopefully support can help.

Fairygirl

I think that's what the other person was finding too. There's obviously a glitch somewhere.  Perhaps we can flag it  up tomorrow and get some help with it

Not very helpful but I added my location today without any issue.

Just tried again and this time I got this one
