There is milkweed in my lawn. What would you recommend that I use for killing it without hurting the grass?
Since these are not too difficult to control, hand pulling would be most effective, especally while the soil is wet. If you haven't had any rain, simply soak the area for about 15 minutes or so beforehand. You can also spot treat the plants with something like Round-up, taking care not to spray the grass. An effective way to accomplish this is by using a shield of some kind, like a piece of carboard. Also, avooid spraying if it's windy.
