I'm trying to figure out the best way to deal with the double-layered landscape fabric that was installed in my planter areas by the developer. They put mulch over it, and I'm planning to create a cactus and succulent garden. Should I just cut holes in the fabric for planting, or should I remove it entirely? I plan on replacing the mulch with a couple of inches of decomposed granite for top dressing. My main concern with leaving the fabric is how it might affect the drainage and soil health since cacti don't like wet soil. The fabric seems somewhat permeable, but I'm worried it might cause root rot. Any advice would be appreciated!

Honestly, I think you should remove the landscape fabric. It breaks down over time and can leach harmful substances into the soil. Plus, it doesn’t really do much in terms of weed control. Cutting holes may seem easier now, but it could cause you problems later on!
You definitely want to avoid mulching over fabric. Mulch is organic and breaks down into your soil, while fabric acts as a barrier that can keep your soil from getting the benefits of that breakdown. Plus, that barrier can hold moisture in and suffocate your plants.
