Hi! Beginner gardner here in Colorado. I bought a Gardenia jubilation plant in late April from Home Depot. Arrived in excellent condition. Fast forward to today and its a mess. No beautiful white flowers , leaves falling off, the buds are brown not white. I water every few days and it has gotten a couple rounds of fish fertilizer. I've added pickle juice and some coffee grounds to the soil after reading that they like acidic soil. Not sure if this helped at all.
Now i realize this plant is not quiet fit for my zone (beginner mistake). Says for zones 7-9 but im in 5. Since its small i can certainly bring it into the house during winter but at this rate not sure it will make it. Help!
