We don't have grass ground cover. One side of the front yard is mostly vinca the other half (separated by the side walk) has peonies violets and naturally occurring grass and of course dandelions. We have a vine that used to be on the retaining wall but is now spreading across this side of the yard. This vine has broad leaves a red stem that sends out roots as it moves across the yard. Invasive! I've been pulling it and gotten some poison on my skin with blisters that look like poison ivy. My husband and I have searched for this but cannot find it.Nothing looks like the photos we have of poison ivy.We do not want to use round up but what can we do? Can you recommend a solution? We have a cat and children who like to run around and play in our yard.
