Winter plant care

I'd like to interview a couple of companies regarding winter plant care for a journal article. If a client asked for help getting their landscape plants through the winter, what are some steps you'd take with them? It could be as simple as avoiding fall fertilization, or you may even use plant covers, etc. If you'd be willing to be interviewed (with just a couple of questions), please message me with an email. I can email you the details and questions.

Thanks.
