Q.Grow Bags Too Near Walnut Tree/juglone
I didn’t realize the tree was a walnut til my very expensive tomato plants in my new grow bags with the pricy soil began wilting. What can be done to save them. If I move the bags, even if the plants can be saved, how do I know the new plant won’t die too?Will emptying the bag & laundering it work?
