How much frost can Oriental lilies stand?
Hi, all. My Oriental and Orienpet lilies came up fast this year, and some are a couple feet tall already. But we did have possible frost predicted for last night and tonight. We lucked out last night, as the temperature stayed around 40. But it is supposed to be colder tonight, in the low 30's.
I really don't know how I would cover the lilies, as they are so tall already. And sometimes covers, if they are laying directly on the leaves, seem to hurt more than help.
I do recall that I lost most of the lilies one year when the temperatures dipped into the 20's. But I don't think it's supposed to get quite that cold tonight. Can these lilies take lighter frosts, but not heavier ones?
