I bought two blue prince(es) hollies from you this year. Neither had an insert indicting cultivation instructions or hardiness zones. I live in Warrensburg, transitionally between zone four and zone five in a good year. What care recommendations do you recommend.
Those hollies are a zone 5 plant. Protection with windbreaks made of burlap would be a good idea where you are. Hollies struggle in windy spots. There is also an anti-desiccant spray called Wilt-Stop that can help get them through. More on that HERE
