Hi, Sorry but i do not know much about BOP plants, Just had a sea change a few months ago to Surfer's Paradise Qld Australia! , and on this plot i purchased i inherited 2 lots of BOP plants each lot has about 30 stems/leafs growing to about 5 feet high, when we first arrived they both looked in good health and flowering, but now that we are heading towards the summer season next month my BOP'S are no longer flowering and some of the leaves are looking unwell , with curls and a little brown the color of rust ! Will you please advise me of what is needed ? many thanks , Regards Charlie
