I bought some plants in 6" pots to have in the garden for fall after many plants have finished blooming. I have some questions:
I assume they are perennials and can be in the gound all year. They have the tiny blooms, some are like a little ball others about 1 1/2 " wide blooms.
can I keep them in pots? should I bury the pots?
should I take them out of the pots and plant in the ground? and mulch for winter?
Should they be cut back after blooming for winter?
