Do I cage them now or wait a bit more?
I have the three Hydrangeas that I need to cage for the winter, two ES and one BB. I know that it isn't necessary but they flower better at my doing so. My question is when do I cage them? Temperatures are dropping to the mid 30's at night and we are having light frosts. I can cage two of them today but really would like to hold off on the one that bloomed it's heart out this year and is now covered in a rich beautiful color that I would like to enjoy for a while longer.
I would also like to cut some of the blooms off and bring them in for the winter but am not sure how low to cut it at this point in time or how that will affect the blooms for next year.
Can someone explain to me in detail the bloom process? When do the blooms form, when's the latest you can cut them and so forth? Thanks!
