I am digging up masses of orange/brown root systems from my garden beds. These roots are not related to any veggies grown in these
beds. To an extent these roots have always been there but this year in great proliferation, meshed and tangled together almost like clusters of birds nests, others twiggy, 2-3 ft long, 1/8-1/4 in diameter....what is this stuff?
I know of several plants that have orangish roots. Two are trees, buckthorn and mulberry. The final one is oriental bittersweet, a vine that produces clusters of orange-red berries in fall. Take a good look at your neighbor's yards. All three of these plants are vigorous growers and their roots will compete with your vegetables for nutrients and water. If none of these 3 appear to be the culprit, post again with a picture if you can.
