Hi everyone, I have about a dozen good sized mop cap hydranges in large pots.
at the end of the season, I have always left the old blooms on the plant to help protect from frost, Then come spring i have always pruned down to a couple of buds.
The plant cut off i then set these off as cuttings.
Well! this year my big potted plants have large areas with no flowers on, so I went on the web to see if anyone else had the same problem.
I ended up on an american site, and the guy who runs it seems to know his stuff, and he states, that if you want flowers next year, do not prune! (only prune out unwanted stems or dead stuff) If you must prune for whatever reason, you must prune before, and no later than August the 1st.
he states, that before this the plant has set next years flower buds, and if you prune after this you cut off next years flowering buds.
what do you folks do??
