I've had these beautiful
plants in my yard for years. I was perusing the search when I read that it is recommended to trim back the foilage as it withers.
I've always been under the impression that lillys, iris' and other
plants like these, take back the nutriants from those leaves for reserves during the winter.
I do trim back the any length of yellow from the leaves, but never the whole leaf.
My
plants really look great, the blossom stalks are about 2 1/2 feet high, red and cream color. I cut the blossoms back when they are finished blooming to encourage new growth.
Just wondering what others do about this leaf thing.
What way is right, or does it really matter?
