I disagree. I agree that it will come back, but poison ivy is perhaps the most sensitive plants to Round up. You can apply two drops on three leaves with a small paint brush, and the whole plant dies. I was able to eliminate it from my blackberries without losing a single bramble. Once the plant dies (3-4 weeks after painting), cut it at the base so it falls to the floor and starts rotting. But I would not plant carrots, lettuce or turnips in there the first year, only stuff that is well elevated, tomatoes, pole beans or cucurbita with a trellis, collard, broccoli, Brussels sprouts, okra, pepper, eggplant. PI usually grows in good soil. You could also lay down cardboard and mulch, and punch holes just for the plants. That will separate you from the PI, but pay attention not to touch the trowel blade while you plant. This second method is probably as good as the first.

Persimmon, the Roundup is not being sprayed, but painted on the cut surface of the ivy stem while the cut is still fresh (ideally only seconds after the ivy stem has been severed). So the Roundup doesn't get on the tree (you should be using so little Roundup that it doesn't even run down the stem of the ivy). And the Roundup which has been absorbed into the ivy breaks down long before the ivy rots, so no Roundup is released from the ivy roots into the soil. Four years ago I had two nandinas at the front of the house (planted by the Previous Owners) which I did not want. So I had them cut off at the soil and immediately painted the cut trunks with Roundup concentrate (41%). The nandinas did not resprout. The dwarf nandina was located between two dwarf Burford hollies -- the trunks were about 2' from the nandina. The hollies were not affected by the Roundup on the nandina stump; they have since grown together, covering the area where the nandina had been. The 6' tall, skinny nandina's trunk was about 3-4' from the trunk of a camellia (shorter than the nandina but much wider). The camellia suffered no ill effects from the Roundup on the nandina stump; it has since grown to cover the area where the nandina was ... I joke that the camellia is trying to eat the house! If you don't want to bother with a jar of Roundup concentrate and a paintbrush, a neater applicator is a small squirt bottle (ketchup, mustard, glue, whatever).

Mia- I had no idea about the pots acting like different zones! I have always loved gardening, flower and veggies, but I have never gotten so into it and so serious about it until this year! I will be able to move the pots so if they need to spend the winter in the garage they can(but who knows at this rate winter might be more like summer). I do love Lantana and it was on my list. I saw some Artemesia and thought it was beautiful. Knock Out Roses where on my list too! But I think I am leaning more toward a climbing rose this year as we have unsightly cut off pole on the corner of the front of our property. Salvia has always been a must plant in my yard! Its too pretty to pass up! And I will DEFINITELY be hunting down a pony's tail and a bunny's tail. I don't think I have ever seen them before and I am in love! I will have to check out your link more tomorrow when I am being forced indoors! But it looks great! Helen- I figured I would have to coat that poison ivy several times before it gives up. But I just can't have it with 2 toddlers running around! mulberryknob- I think it was a sucker. I did just like you said and followed the roots back as far as I could. The one that tied to the mother plant either broke before I could go the whole way back, or it wasn't tied to the mother tree at all. Either way I took as much root as I could get. One of them was going under the foundation of the house, so I had to cut it off. I moved it to the north side of the house since the row of them is on the west, and there is one on the south already. My husband thinks I am crazy, but I am hoping this is like the Japanese Cherry and I can prove him wrong. So any tips for nursing it along would be appreciated!

This does not look like poison ivy to me. The stem looks too smooth and green. Poison ivy will have a hairier stem that in parts will look spotted like a rose stem. Also, like previously posted the groups of leaves are not opposite each other. In the spring, new leaves will start out red, then turn green. The new leaves are quite shiny, glossy even.
