Hi. I have this nice China rose at home, and it was blooming just fine. But this season the blooms started to "detach" themselves and fall off. What might be the case? https://imgur.com/a/ircXc48
I can't say for sure, but the bloom fall might be "balling", a condition caused by the bud getting wet (rain or dew) and then drying quickly in the sun. The outer petals form a hard barrier, and the bloom can't develop properly. OR, it might be lack of proper ventilation--rose bushes that get too thick cut off air circulation to the buds and blooms. Pruning fixes that.
