I have a couple of self sown hollyhocks that I transplanted into pots, intending to plant them out next spring. They are doing really well but will soon have outgrown the pots. Should I plant them out now or pot them on ??? i wanted to keep them in pots as long as poss as most of the hollyhocks in the border have rust.
Any advice gratefully received!
I'd pot them up until the end of September... :)
Thanks, Saddad - I'll put it on the to do list for tomorrow!
