I have made all the mistakes that you are talking about and maybe more.
I need information.
I have been potting new arrivals and I plan to overwinter them in a cold greenhouse. This is an addition to my garage and I can easily control heat and, of course, I can water and work there.
All these plants are from Maryott's.
What is the coldest temperature that I should allow for really safe overwintering?
How should I modify watering?
I am rather new to daylily growing. I am really knowledgeable about hostas.
I appreciate any information that might give me.
