| Jul 29, 2016 at 3:47 | comment | added | Traveler | Oh, I also put the chippings around the rose bushes and they started looking sickly as well. I just replaced that mulch earlier this week. BTW, it didn't seem to affect the beans (both green beans and dry shelling beans), goji berries, black elderberries or any of the fruit trees (I have 15 of them). Even the apple trees seem to be unaffected. | |
| Jul 29, 2016 at 3:40 | comment | added | Traveler | I'm going to have to replant the asparagus (arrrrg!) and wait another couple of years before I can harvest it. This would have been the third year since I planted the original asparagus. I guess I'll chalk it up to the cost of education. | |

It's been about a week and a half since I did this, so I'll see how things look in another couple of weeks. | |
| Jul 29, 2016 at 3:36 | comment | added | Traveler | I have about 4000 sq ft of space between the garden and the food forest and only the plants that had black walnut mulch seemed to be affected. It decimated my potato plants and my asparagus. It also caused the blueberries (I have a LOT of them), raspberries, tomatoes, grapes, and tea plants to turn light green and sickly looking. I have spent about 20 hours removing all the black walnut chippings, fertilized the plants with cotton seed meal, bone meal, and sulfate of potash. | |
| Jul 29, 2016 at 3:22 | comment | added | Traveler | The mulch I use is tree chippings from a local tree service (it's free). I always ask what kind of trees are included in the chippings. When this particular load was delivered I asked if it had any cedar and was told, "No, but it does have black walnut." At the time I was not aware that black walnut was a problem. | |
