I put out some lilium bulbs several weeks ago. They seemed to be doing well, However I have had to water lightly every day because I am in Oklahoma and the weather is unusually hot right now. I skipped a day of watering thinking they were big enough to go maybe every other day, ready to bloom. Big mistake when I saw them the next evening more than half of them were yellow and wilting. I am not sure of the exact breed all I know is they are common and the bulbs came from wal-mart. can I cut them down and still get blooms this summer?
