should I cut off stems that have lost their flowers
We have an area of beautiful Crimson Pixie. In previous years I have always cut off the stems that have lost their flowers. And it seemed that it didn't take too long and the leaves on the stems started to brown and wither right up the stalk. This year I did not touch them and they are not having this problem. I did dig up the bulbs last fall and discarded all the little ones and then repositioned the large ones that were left so there was good space between them. It was a weird winter, but we have had good rains this spring. So much for the history. My basic question is as I posted. Do you need to so to speak "deadhead" the stems after the flowers fall off?
