Hello all, I have Ornithogalum sp. or umbellatum all over my yard. It is early spring and only the leaves are coming up now. These plants were very charming at first but now they have filled my yard. My grass is doing poorly and I wonder if these bulbs take a lot of nutrients from the grass. In any event, it has become too much of a good thing and they have to go. My question is, if I keep cutting off the leaves, will it eventually kill the bulb? Besides digging them up (which would take forever), is there another way to eliminate these from my yard? Thanks so much.
