has anyone had success spliting hardy minnesota mums. i have a few larger ones to split???? an not sure when would be best to split fall or spring..
IMO spring is the best time to divide mums. Those divided in the fall may not survive the winter. I divide them soon after they have fully emerged.
I agree with MN winter sow Gal. I will divide most any thing any time- but the spring divisions seem to always suffer less set back with the mums. In fact- they usually put on a great show that fall! I will start dividing these as soon as I can tell what it is after it breaks dormancy. Just an inch or 2 tall.
