Gardening

Is this near other plants? I often see it around trees.

If it is not near other plants, what I do as a less and less capable physically older person is...resort to spraying things with RoundUp. Yes, evil RoundUp. It can take a couple of weeks for stuff to start dying, despite their claims of one week. It comes in premixed spray bottles, so you can avoid the whole mixing and big sprayer effort.

You could also go the cover it with flattened cardboard boxes weighed down with bricks or somesuch. You can buy cardboard boxes at UHaul.
