I planted about 50 glads relatively late, in early or mid-July. They flowered over a number of weeks. The last bloom stalks came up just a couple weeks ago. Some of those buds didn't open at all, others just a little, and look spotty and crinkly. What is that about? Online instructions say to dig and dry for storage 4-6 weeks after blooming, but that would mean I should have dug some over a month ago, and others not till November. Not practical for many reasons. Do I just dig and trim back all now?
