These Rudbeckias are taking over HELP
What started as a mixed bed of Dahlias and Ruds is now basically a forest of Rudbeckias. Towering over everything.
I cant seem to add more pics rest are here https://notesfromthebarn.blogspot.co.uk/search/label/Home%20%26%20Garden
Can I split these up once they have stopped flowering a split them all over the other beds or do i have to wait until next spring
