Zone Isleworth | d.r.thorn3108 added on June 11, 2016 | Answered

Do hydrangeas have to have the old flowers picked to let the new one thrive? My hydrangea has new buds growing but I have left the dead flowers attached. I was told never to pick old ones off. Please can you help? The photo I have sent you is from last year.
