What are the pros and cons of using grass clippings for weed control in the patch? Should clippings be avoided all together?

In order to effectively block the sunlight to prevent weed germination, you need a fairly thick layer of material. One concern is that if the clippings are wet, they can mold providing an inoculum for disease. Grass clippings are low in lignin and hemi-cellulose and will decompose easily. If you use something that is more complex carbon chain (higher in lignin and hemi-cellulose) it will not decompose as easily and will dry out quicker when wet.. Materials like straw or peat moss are better choices. On the other hand grass clippings will provide nutrients as they break down.

You must be sure that the grass clippings haven't been treated with any weed treatments. That will leach into your garden area. Better to use the hoe and compost the grass clippings with last years leaf pile. I've also seen a ton of white grubs come from grass clippings...Not sure if they were imported with the grass or just a great place to lay eggs.

Fresh grass clippings get pretty hot. I have used them but this year, I will let me dry some before I put on the garden. What are your thoughts about leaves that are not composted but shredded?

I believe leaves (shredded or otherwise) can shift the pH of the soil toward the acidic side while decomposing. I suggest being careful there.
