Q.Gardenia First Flower
My 2 gardenia bushes get a few hours @2 hours of direct morning Sun daily plus plant light at night 8 hours. One plant produced its 1st flower which Was small this is a gardenia mystery. It looks like some more buds might be coming. Ive had them 5 years. Does one flower always follow with more and will the coming flowers be bigger? Fertilise how often? Germany
