Hi. I bought 6 gardenia florida plants and planted them 3 months ago. They produce a lot of flower bulbs but wont bloom and just fall from the plant. Some have a slight black coloring. I am doing some research about this and one of the cause might be my soil is not that acidic as this kind of flowers need acidic type. I live here in west suburb of melbourne.
Anyone who have experienced this with a gardenia florida? Any advice is appreciated.
thanks.
