Landscape fabric...my nemesis. When clients ask why Landscape companies use it, I tell them, job security because they'll be back in a few years to rebuild your garden and sell you on it all over again.
You laid landscape fabric under your mulch.
The landscaper said it prevents w**ds.
5 years later:
Weeds are growing THROUGH the fabric.
The soil underneath is compacted, pale, and lifeless.
Your plants are struggling and you don't know why.
Landscape fabric is one of the most damaging products
regularly installed in American gardens.
Here's what it actually does:
Blocks organic matter from reaching soil. Mulch
decomposes ON TOP of the fabric, never reaching the
soil below. Over time, the soil is cut off from its
food source.
Suffocates soil biology. Earthworms can't move through
it. Beneficial fungi can't expand. Soil microbes lose
oxygen exchange. The soil becomes biologically dead.
Creates a barrier to water. Over time, the fabric
clogs with fine soil particles and becomes nearly
impermeable. Water sheets off instead of soaking in.
Your plants' roots sit in dry, compacted soil.
Weeds grow anyway. Seeds land on mulch ABOVE the
fabric and germinate. Their roots grow INTO the fabric,
making them harder to pull than if there were no
fabric at all. You created a w**d problem that's
worse to manage than bare soil.
The fabric deteriorates. It tears. It bunches. It
works up to the surface. It looks terrible within
3-5 years.
What to use instead:
4 inches of wood mulch directly on soil. That's it.
Mulch suppresses w**ds, retains moisture, feeds soil
biology, and breaks down naturally.
Replenish mulch annually.
Cardboard under mulch for heavy w**d areas — it
decomposes within one season and is actually beneficial
for soil organisms.
Landscape fabric is a product that creates a problem
it claims to solve while destroying everything
underneath.
Rip it out. Mulch directly. Let the soil breathe.
