It’s quite an interesting plant, very good for wildlife
“Soft rush is an important component of wetland ecosystems, where it plays a variety of roles. It can help to stabilize wetland soils, preventing erosion and sedimentation. Its dense stands provide cover and nesting habitat for a variety of bird species, including waterfowl, rails, and marsh wrens. In addition, soft rush provides food and habitat for a variety of invertebrate species, including snails, insects, and spiders.”
– soil is clayey, so stays soggy longer than most, but I don’t think it qualifies at wetland, or in need of stabilisation.
– Even if I left patches permanently to grow to the “dense stands” of 2-3 feet, I’m pretty sure we’re not going to have waterfowl nesting while our two boys play football round them!
– As for the spiders and the snails and the insects: do they like soft rush any more than than they like all the other stuff that the soft rush is displacing? Certainly the pollinators aren’t getting anything from it.
Honestly, I’d be happy enough to learn how great it is if it meant I could do less for longer with the knowledge that it’s worth it.
You could take up some of the lawn and sow a clover or herb lawn.
Isn’t that just another way of saying “kill what’s there and start again”? 😀
