I pulled up the garlic and red onions this evening. Tomorrow I will most likely have poison ivy. I didn't see the poison ivy until I was almost halfway through pulling the garlic. I used the Tecnu soap, hopefully it works. My yellow onions were harvested about three weeks ago. They made better bulbs than the red onions. Did exactly the same thing with both of them. I don't know what happened. I killed the weeds and poison ivy with boiling water. In the next few days I will plant cucumbers in place of the garlic and and peppers in place of the onions.
