I have Pampas grass in my garden. It has stems but no plumes. What could be the problem. Many thanks.
Is this every year or just last year David?
Just last year !
Almost certainly the lack of sunshine we had last year. Fingers crossed we get better weather this year and hopefully it will then produce plumes for you again. I had a huge clump until a couple of years ago but it outgrew its space and began to die, so I helped it on its way with a bit of glyphosate. The stump will take years to rot away though and is too tough to remove without a tree stump grinder.
Many thanks for your comments.
