Hi, 

Pesticide regulations in Montgomery County pertain to lawns, playgrounds, mulched recreation areas, or childcare facilities, so if this is a private garden it should be fine to use a non-organic herbicide if necessary. You can read about how to deal with poison ivy on our webpage. Cutting and carefully spraying with a chemical systemic herbicide such as glyphosate or triclopyr to help reach the root system.

With that being said though, these photos do not appear to be  poison ivy. They might need to be re-sent more clearly (close-ups where we can see leaf arrangement and if they are compound). We think this looks like an Ash sapling and possibly Bishop's-weed (Aegopodium) but to be safe you should protect your skin when trying to take photos and wash hands or pruner immediately afterwards. 

Let us know if you have further questions or feel free to send back additional photos.

This isn't poison ivy because we can see thorns in the photo labeled 1. The other photos don't clearly have thorns but they look like the same leaves, so assuming it is the same type of plant.  It is probably a type of bramble (Rubus sp.), as in a raspberry or blackberry shoot, but there are a lot of different ones and it can be difficult to identify beyond that. 

 You can wear thick gloves to protect your hands and pull or dig it out. The roots can be tenacious so it may pop back up. If you want to be a little more proactive you can cut the stem and squirt a little herbicide on it to help with any more shoots popping up, but you still may have to do this on occasion. 

You can learn to ID poison ivy on our website and there are plant ID apps for your phone you can try. (sometimes they aren't always accurate) But when in doubt feel free to send us photos again!
