Watering Gardenia Bonsai but leaves are drying out
I just received a Gardenia Bonsai tree as a Valentine's gift from my husband this week. I have been keeping the soil moist and watering every other day by placing the plant and humidity tray in about 2 in of water and keeping it there until the bubbles stop (about 5 minutes) just as the care directions said to do, however several of the leaves have dried out and even some of the buds are turning black. I noticed when I received it that there were several black spots on the leaves as well. What am I doing wrong and what can I do to save this beautiful plant? Thanks so much for your help, I can't explain how important it is to me to keep this plant alive and healthy!!!
