I hope I read your information closely enough. You need to give this plant fertilizer. It is struggling on many accounts.
Those clippings are freshly killed organic material. Anything alive that dies has to be decomposed. Starts instantly. Those decomposing organisms need nitrogen for energy. Non decomposed organic matter causes nitrogen to be depleted.
If you want figs someday we need to talk about formulations of fertilizer to promote reproductive growth. Right now this plant needs a balanced fertilizer. Watering is not a problem at all...just chemistry or 'nutrients' your plant needs desperately to make its own food via photosynthesis. The chlorophyll in your plant are being put on hold. Plenty of sunlight, water but no chemicals that that plant needs to do photosynthesis. Nitrogen, Phosphorus, Potassium and possibly some micronutrients.
Weeds really really get hugely magnified as a problem. They just are not...a big deal. Fertilizer is just as important as water and sunlight and drainage. Try Osmocote 14-14-14 extended release. Very safe very sane. Lasts a long long time.
