I am new to gardening. Recently it was brought to my attention I have poison ivy in my back yard. The problem is it is mixed with hostas I would like to keep. What would be the best way to remove the poison ivy? I have considered digging it up and transplanting the hostas to the front yard but I worry I'll be bringing the poison ivy with it. I would hate to have to scrap it all and start fresh. There is black tarp near it which makes me wonder if the previous owners failed to get rid of it. Please help!

There is a poison ivy spray for sale in garden centers or on line. It is fine to use around other plants. Just spray according to the directions, don't over spray.

Welcome!

How big are the poison ivy plants? If they aren't too big you may be able to pull them out (wearing protection for yourself of course). Otherwise cut them off and paint the stump immediately (with RoundUp or whatever brushkiller you can get there). Again wear protection. If the plants are small and you can do it without hitting the hostas with the spray you can just spray the leaves of the poison ivy (invert buckets over the hostas if you can). If you can post a picture so we can see the scale of the problem it would help with advising the best course of action.

BigBill, can you post a link to the product you are thinking of? Poison ivy killers generally kill other plants as well so it would help to be more specific.

I can't think of the exact chemical but I have seen cans of it, Ortho product I believe, on the shelves of Home Depot and Lowe's.

Any 2,4-D herbicide will kill poison ivy and not harm grass, BUT it will also kill any other broad leaf plant. I don't know of anything that will selectively kill poison ivy, unfortunately.

I successfully use a $5.99 PI Spray from Ortho from Home Depot. It cautions not to get it on other plants. So maybe you could spray it into a cup and paint it on the PI. It takes awhile but works down to the root.

I was pulling poison ivy out of the garden myself last week...
pretty easy to remove.

If you dug the hostas and moved them... that would certainly work... any poison ivy hitch hikers (that showed up), would be very easily removed from the hostas wet root balls after you planted them... you'd have to water them a good bit after moving them anyway... that will make anything else pull easily.

I second what sooby said. I kill poison ivy, Virginia creeper and all sorts of other weeds by cutting them to the ground and spraying the stumps with glyphosate concentrate. I keep these in pockets when I'm outside.

I wouldn't be that interested in that Hosta to bother digging since I get PI so easily. They're so easy to find inexpensively about anywhere plants are sold, but it sounds like you have more than one and that the cultivated area is not just the area in the pic. I would smother everything (with cardboard, not plastic) in the pic & start over next spring. But if there is someone willing to dig out the Hostas & the other plant that looks like Platycodon, they're definitely worth saving. Just ask them to gently shake the dirt off of the roots, then replant elsewhere right away. Then watch closely for sprouts since seeds could be lodged in them. And sprouts of anything else you did not plant. Grass, PI, other weeds can take over so easily if you are not paying attention often & pulling anything but your desirable plants. Mulch also helps cut-down on the amount of unwanted sprouts of any type.

Starting a garden by smothering & waiting until the next year to use is how I've always started, except a few areas where I live now. Big mistake I'll never make again, will always smother first in the future.

Can you get a sharp close-up of mainly the poison ivy so we can make sure it actually is poison ivy rather than something like Boston ivy?
