Please help. Our 8 year old is allergic to Lamb's Ear (especially when it blooms.) We've dug up everything that the previous owners of our home had planted, but it seems to have taken root in the yard and just keeps spreading (and spreading, and spreading.) How can we kill it once and for all? Thanks so much for your help!

Cutting, digging and pulling are the first steps in removing unwanted vegetation. I know you've already done this, but there are some roots lurking in the soil and they don't need much encouragement to sprout new stems and leaves. You can get the upper hand if you consistently cut any new sprouts down with a hoe. As long as the stems cannot develop leaves for photosynthesis, the roots will eventually run out of stored energy and they will die. But you have to be diligent about whacking down the sprouts as soon as they appear. The next method is to spot treat the lamb's ears with a broadleaf weed killer such as 2,4-D (dandelion killer) or with a vegetation killer such as Round Up. Either of these products can harm your other plants so you'll want to use them carefully and target only the lamb's ears. Wish there were an easier method of eradicating this plant! Good luck with your project!
