Good Day, In the past 14 years since inheriting my home from my late parents, I have noticed peculiar plants growing more widespread in the yard each Spring. See pictures #2 and #3. These plants grow in clumps that are taller than the grass. These clumps are spread throughout the front and back yard, and they have become so numerous. I was able to pull up one whole plant from some softer dirt. Picture #2 shows that there is a bulb at the bottom. The other ones that grow in the yard only come out partially when pulled. There is another plant with wider leaves that grows only in the front yard. See picture #1. There are also snowdrop flowers growing in several places throughout the front yard. I know that my parents planted many Fall bulbs in their front flower beds. Would those have spread under the grass? I am wondering if I should treat these plants growing in the yard (though there are so many right now) or let them go since they seem to eventually stop growing in late Spring/early Summer? Does their presence damage the grass by squeezing out growing space that the grass won't fill in? Thank you for your time and advice. Best wishes.
