Can I Put Walnut Chips in My Garden

Yes, you can. I would recommend that if you do, just make sure to test your soil once a year to keep an eye on the nitrogen levels. Sometimes the decomposition process of wood chips of sawdust can leech nitrogen out of the soil, but mostly the benefits of adding a mulch of this kind outweigh the problems.
