Disasterous lawn....mushy, moles, help!
My parents' organic lawn is getting unbearable, so any help would be greatly appreciated.
It's a 23-year-old lawn, started from sod, on Northern/Central Long Island.
It was beautiful and healthy whilst chemicals were used on it, while the trees in the yard were smaller, and while professionals cared for it, but once they switched to an organic lawn care service (and the trees grew taller/fuller), the grass began to degrade rapidly. The first few years after the switch, it was patchy but bearable. They tried to fight back by re-seeding (possibly tilling, too) before a rain with all different varieties of seed, but some areas took and others didn't.
Years later, the lawn is now soggy and graveyard-like in many places. The rabbits and squirrels have largely vacated, and moles/voles have taken over -- leaving huge trails of dug-up grass and tons of eaten roses and hostas that had been there for years, and some, even decades. They even ate through metal-netting-wrapped bulbs, and stuck around when they tried to use castor oil to deter them. In some areas, a weird moss-like substance has grown over the mushy grass, and it looks like tiny, tiny little ferns. Mushrooms have also increased (they were always present, though), especially more red and orange varieties. Dandelions still grow in the grass, as does clover, if that is any indication.
Do any of you have ANY suggestions or ideas? They are getting hopeless.
I believe they had the soil checked once, but I think they were told it was fine....
