I have heard the best time to actually plant them in my climate is in the spring so they get a good root system, if you do it in the fall
they may not do well through the winter. I have some beautiful full assorted colors of Mums already established and I cut a few good chunks off, cut off all the buds and blooms and planted into a pot and watered well. My question is did I do that as I should of? and next question is now do I put it in the dark, in the garage or where? Thanks!

I have never heard of overwintering mums in such a manner so I don't know if it will work.

I can say I grow LOTS of hardy mums. And fall planting has only been successful on two plants. This year I needed to move lots of my mums. I potted them up early summer and only got them planted late August. So we'll see if they over winter.

I did in the summer as my sister said, and does....she cuts a good chunk of Mum off and removes the blooms and just sticks it in the dirt
and gets a new plant, the one I did this with in August is alive and well. At the time I only did the one because only recently did I decide that
in spring I will be needing about 5 more Mums to plant all along the embankment that is up above our driveway. So I thought why buy if I
can harvest from what I have, I know it may take a few years for them to bush out and be bloomed, but I am patient and love a experiment.

I think they need really well draining soil if water sets on the roots over the winter they rot. Of course to loose of soil will cause them to dry out, they need mulched well. They are a hit or miss kind of thing I think.

The first picture is the drive way embankment where I want about 5 more Mums next spring. The next picture is the ones that come back
the past 2 winters, in the spring I need to remove the smaller of the two as they are too close together.

Linda, you can always take cuttings in the late spring. They will get full size by fall.

And they will bloom the same fall. I always divide my mums in the spring. Just remember, don't cut back your mums until springs. Stems are hollow and if the moisture gets down into the cut off stems it can freeze out the mum.

What about my Asters? Can I cut them back when they dry up?
