The rose of sharon in my garden had a beatiful display of flowers in the late summer. Now there are hundreds of new buds forming in our cold zone 5!!! I doubt it can come to flower in time before the weather turns nasty. Should I pinch off the bud to save its energy to prepair for winter? Or it doesn't hurt to leave them alone in case they can bloom?
They are 4 years old, 6' tall and very healthy. Thy are located near the house in a protected spot from wind. The weather is 5C high and 0C low (40F and 32F)
Thanks.
