New Hybiscus Dropping unopened blooms
I have a first hybiscus, a double peach.
After bringing it home, it immediately started dropping approx. 4 unopened blooms per day. I moved it to a less drafty location that was south facing but near a door, it's near a south window now and no drafts. Temps range from 70 falling to 62 at night.
I've watered once in about 2 weeks, when the soil seemed to be getting dry, didn't let it sit in water.
Looks very healthy, I don't suspect any insects....
Any suggestions as to why the massive bloom drop?
Also, approximately how often should I be watering and fertilizing (and with what!) to maximize blooms.
