Flowers dried up and died
The Optimara Hiroshige that I had just bought had several blooms on it with several more on the way and today all the existing blooms have turned brown and died but the buds are still present from before. It is getting indirect and filtered sunlight from an east facing window that is approximately four feet away from the bookshelf it is on. The potting mix is moist but not soaked and it is in the same pot it was in when I bought it (4in pot). Also the leaves are exhibiting no unhealthy symptoms. The other AV I bought at the same time still has all of its blooms and is doing well so what has happened with this one? Thanks for your help!
