|I have a double pink hollyhock that I started from seed 4 or 5 years ago. I cut it back each year after it's done blooming and now it's grown so large that it's taking over one whole end of the garden. I am wondering if there is some way to divide it? I have other areas in the yard to put transplants, but I'm afraid to move this plant since it's doing so well. Also, for some reason, I haven't been successful at propagating seeds saved from this plant. Any tips are appreciated.|
|That's great that you've had such good luck with your hollyhock! Hollyhocks are perennial, but since they frequently succumb to a common rust disease they are often treated as a biennials. They do, however, readily self-sow, so it's possible you are seeing multiple generations of plants. Have a look around the perimeter of the plant to see if you can find some seedlings--these are probably your best bet for transplanting, rather than trying to divide your thriving plant.
Hollyhock seeds need light to germinate, so when you sow, don't bury the seeds--simply press them onto the surface of the moist growing medium.
