Hey, I planted several rosy sedge’s and they must be super happy because 2 of them blew up in size in a matter of weeks a bit larger than I had anticipated. Wondering if these guys can take a trim once or twice a season? They have the seedheads on now and have flopped a bit spreading out at almost 3ft. Their foliage has started to get mixed up with some foam flowers which actually seem to appreciate the additional shade but looks a bit untidy. Anyhow, love these sedges would be great if I could just trim them. Let me know!
