Fresh grass cuttings can get very hot and stacks dumped by

them as a weed suppressing mulch between rows (avoiding stems) until the

That's interesting. You ought to contact the no-dig system pioneers
about your find because mulching the entire area and covering the
entire plant as it grows (giving it a helping hand as it sometimes push
the mulch instead of breaking through it) is very much how we've been
doing it for err... a long time. The key here and perhaps your point,
is that you need to let the first layer of mulch to dry before applying
another.
