I'm new to vegetable gardening and living in Central Texas (zone 8b) has its challenges with the intense heat and strong winds causing my soil to dry out quickly. I applied wood-chip mulch to retain moisture, but I learned that it might rob my soil of nitrogen. What should I use instead for mulch? And now that I have these wood chips down, should I remove them or leave them?

If you can get your hands on straw, that’s a great option! Just be sure it’s the real stuff and not some weird sticky version for construction. I personally like to use wood chips but mix in some leaves for added nutrients. Any natural mulch can help your plants, so don’t stress too much about it!
I’m a fan of living mulches like clover! Just keep trimming them down, and they’ll give you mulch plus nutrients for your plants. It’s a nice way to keep the soil covered and healthy.
For garden mulch, it’s best to use organic materials that help with moisture retention while preventing weeds. While wood chips can tie up nitrogen in the soil, they primarily sit on top, so you might still be okay if you’re not tilling them in. I like to use leaves and grass clippings as mulch because they’re high in nitrogen and break down quickly. Honestly, you can experiment a bit! Keep the wood chips in one part of the garden and try something else like leaves or straw in another area. Just take notes and see what works best for you. Good luck with your new veggies!
Actually, wood chips on the surface aren’t that much of a problem unless you mix them into the soil. I’ve been using them for my pathways and have leaf mulch in my beds. Just remember to keep your mulch layers decent and let nature do its thing. If you’re worried about nitrogen, you can boost your soil with a little urea on top. It’ll help to create a nutrient-rich environment. Keeping things no-till works wonders too since it promotes worm activity and enriches the soil.
