You have just encountered one of the drawbacks to using membrane janet. You can neither mulch nor feed ideally, viz., adding fertiliser around the roots.
your only option is to liquid feed once a week, at least once a fortnight.
I have removed so many membranes for various reasons and plants have responded with renewed vigour. Instead of looking pale and starved they take on better size and condition. membrane replaced with organic mulches control weeds equally as well. i cannot imagine not being able to apply thick mulches to my plants as I have been doing these past few weeks.
Annual weeds tend to root into membrane material and mosses too tend to populate it.
many will disagree with me ...gardeners do that .....so others will possibly offer an alternative to liquid feeding
