Q.hardy hibiscus
i will be moving in july, and have 2 hibiscus plants i need to transfer
they are 7 years old and have had no problems with them blooming or coming back every year
can i transplant them while they are blooming?
It's best to wait for the flowers to fade, but it sounds like your move date is set, so go for it. The fact that your plants are relatively healthy will insure better chance of survival and re-establishment in your new garden.
