The flowers on my hydrangea plant are all dried out and look beyond help. It currently lives in a little pot on the balcony. Would it help if I cut it back, so got rid of the flowers altogether and put it in a new larger pot? I don't know if you can make out on the second picture that there's new growth, New leaves I think, at the bottom of the plant. If I cut it back would it grow again?
