OK to plant lilies after frost?
I just bought several kinds of Orientals. 4 Stargazers in a deep pink, 4 mixed orientals (32"), 3 Casa Blanca; also 4 Regal Trumpet lilies.
However, the garden is currently STUFFED. I have some dahlias and annuals in there to give me fall color. It's a new garden and I had space to fill temporarily. Most are smack dab where I want those lilies. I was planning to buy in spring but I succumbed to temptation (price was right).
I consider myself pretty tough but I cannot willfully kill a dahlia (not when they're blooming their heads off like that...!). Can I wait to plant the lilies until first frost, then dig the dahlias? Or will the lilies have insufficient time to make roots? I'm in Zone 5, Chicago north suburbs. I have experience only with asiatics.
In a pinch can I hold some til spring? In case the weather becomes too horrible to be outside after the frost. I do have space in a holding bed if that is a better option. I planted asiatics this spring and though they bloomed, I felt they were on the short side due to planting late (already sprouted).
I bought alliums too: if anyone on the Lily forum has opinions on planting time for those please chime in. (I KNOW you plant other things besides lilies :) ! Though I will post that on the Allium forum too.
