As another member stated, sometimes it's easier to build a compost/mulch pile in rings around established trees/banana mounds and so on, water well then dump say 3 handfuls or so of vermi worms (a course sieve thru a vermi bed/plot works just fine for harvesting worms) then let them loose in the new compost pile and let the worms eat their way thru and poop out the castings in situ.
Use pure castings after fruit set as it's like high nitrogen fert - the new leafy growth will help protect the fruits from too much sun but if you apply castings during bloom time some veg and trees abort flowers and just grow new leaf flushes instead.
Not sure if you are referring to me,
but, i do that.
i have mostly "guilds" around/under my fruit trees
where i grow smaller plants like aloe, sage, comfrey, basil...
so there are a few plants in a raised area
The whole area is heavily mulched with grass clippings, leaves,
sawdust, clippings, coffee grounds etc...
usually wood chips on top.
I have a large worm bin and put all my kitchen scraps,
and some coffee grounds from Starbucks in to feed the worms.
It got so productive, that when i use the worm castings, i dont bother taking all of the worms out
and putting them back into the bin.
i might grab %50 of the easy to pick worms and put them back into the bin,
and let the rest go under the fruit trees.
I did this for 2 years, and now there are stable colonies of compost worms
all over my yard. You just need a deep mulch layer
and add some green stuff like grass clippings on occasion to keep them fed.
fish emulsion and molasses will fed them also.
i add spirulina, fish emulsion and kelp to my worm farm on occasion
the worms break them down into plant-accessible minerals.
high in micro-nutes.
They work 24x7 for you
they dont complain, and you never have to pay them either.
here is a short video of a spot where i lift the mulch and compost
and find red worms hard at work.https://www.youtube.com/watch?v=qvAW01u2Dzw
