Answer: Mulch is an excellent way to reduce weeds, maintain soil moisture and improve the soil as it breaks down over time. You can use pine needles, partly finished compost, rotted leaves, straw, shredded bark, or any other organic material as mulch. There is one caution in using pine needles as mulch in a vegetable garden, and that is that the pine needles are fairly acidic and can lower the soil pH as they decompose. If your soil is already somewhat acid, this could make it too acid for most vegetables to grow their best. But ornamental shrubs, trees, and most perennial plants will be happy growing with pine needle mulches. Best wishes with your landscape!
