Agree with John, you have a dilemma!
Thoughts revolve around the depth at which the fabric is at, in absolute terms and whether you pierced the fabric to plant. The size and variety of plant would also restrict your options.
Clearly, if the plant is such that it would root through the fabric, without a piercing, it will be compromised. The fabric will not degrade in most circumstancees.
If you pierced it to plant, then you might be able to join up the holes with a bladed tool and withdraw the fabric in ‘ribbons’.
If you have planted shallow rooting crops,such as salads, then you may be able to abandon the fabric, building up the depth over years. It will remain a pain.
I have one bed covered in mypex(which was the first one laid down before I discovered no-dig) which has strawberries planted through it. They are due to be replaced after this season. An experimental attempt to strip out 1 row last autumn resulted in being able to pluck out a row rooted for 3 years, as if it was a very tufted carpet ! The fabric remained almost intact.
