Starting with your name and location will help.
It helps to facilitate communication, especially
on agriculture lists where context is so important.
Geography and location says a lot about the climate,
soils, plant species, and other agricultural characteristics.
Also, how "many" fruit trees are you talking about.... 10 or 100 or 1000.
Those three numbers represent three totally different
cropping systems, equipment needs, and scale of operation.
Grass is especially tough on young trees. It can stunt
"Devil's Grass." That's what bermudagrass used to
be officially called in the old days, by farmers.
It will laugh at daffodil bulbs, then it will run them over.
Interestingly, I have a row of garlic chives about 60'
long that persists on its own with just an occassional
brush-hogging down each side. It seems to have
remarkable weed-suppressive capacity.
Allelopathy works in certain situations, but it is
pretty specific. A mow-killed rye cover crop mulch
can suppress weeds fairly well for about 30-40 days
before weeds start germinating and creeping through.
In contrast, rye that is incorporated as a green manure
has little weed-suppressive effect.
Fencing is another consideration to protect young
fruit trees, when deer are present.
