The biggest disadvantages of landscape fabric are compacted soil, poor water flow, and trapped roots. You won't notice these issues during your first year. They creep in over 2 to 3 seasons and get worse every year after that. By the time you notice the damage, your soil and plants have been suffering for a while.
I helped a friend remove fabric from her beds after about seven years. We spent a full Saturday on our knees pulling strips of black material from the ground. Every piece had roots woven through it like thread through a needle. The shrub roots had fused to the fabric, so pulling it meant ripping roots apart. When I looked at the soil under the fabric, it was gray and lifeless. Beds just ten feet away without fabric had dark, crumbly earth full of worms.
Here is what goes wrong over time. Tiny bits of decomposed mulch, dust, and dirt settle into the fabric pores and clog them shut. Once those pores close, water pools on the surface instead of soaking down to your plant roots. The fabric also stops air from moving through the soil. Your earthworms and helpful microbes need that airflow to survive. Without it, they die off or leave. This causes serious landscape fabric soil damage over time. Healthy ground needs billions of tiny organisms to break down matter and keep the soil loose.
In my experience, the worst part is what you can't see from the surface. I tested the soil in a friend's fabric-covered bed with a simple squeeze test. It clumped together like modeling clay and wouldn't crumble at all. Soil from a nearby bed without fabric broke apart with a light touch. That difference tells you everything about what years of fabric does to your ground.
Penn State Extension recorded one of the worst removal cases you'll find. A fabric that had been in place for 20 years took 2 workers a full 2 days to pull out. The soil underneath felt like moist pottery to the touch. The crew had to haul in 40 bags of fresh mulch just to get the beds back to a usable state. That removal work cost far more than what the fabric cost to install in the first place.
One of the worst landscape fabric problems is how fast weeds return. Seeds blow in on the wind and land on the mulch sitting over your fabric. Those seeds sprout in the decomposed mulch within 1 to 2 weeks in warm weather. Now you have weeds growing on top of the fabric. Their roots thread down through the pores, which makes them harder to pull than weeds in plain soil would be.
If you have fabric in your yard right now, look for these warning signs. Water pooling on the surface after rain means your pores are clogged. Your plants looking stressed or stunted despite watering means roots can't spread. Weeds growing just as thick as beds without fabric tells you the material has lost its purpose and needs to come out.
To remove fabric safely from your beds, cut it into 2-foot-wide strips with a utility knife. Don't pull large sheets because you'll rip plant roots along the way. Work around root zones and cut the fabric free from stems. After you pull everything out, add 3 to 4 inches of organic mulch to feed the starved soil. Your beds will bounce back within one growing season once the ground can breathe and drain again. The cost of that mulch is a fraction of what you spent on fabric and staples in the first place.
