i dont let myself get hung up on labels.
i am growing dozens of fruit trees, dozens of herbs,
roots crops and flowering plants.
i am still pretty much in the early phases, i only started on it 3 years ago
and the first year was a 1/2 hearted attempt.
I just gfot 3 yards of soil in, and ordered a few 3 gallon plants.
at some point i want to be able to not see any grass.
i know i can sheet mulch it all now, but its a lot of work
and i have no help.
i have salvaged 2x4 and other wood and materials as walkways and borders
i have several groundcovers growing, and chop + drop a lot of my mulch
i even got a used wood-chipper (i need to fix) and a dead tree ready to go.
I am also experimenting with border/zone pushing.
i am in New Orleans (zone 9) and growing mango, papaya, guava etc...
THere are a lot of people in California and Fla that push zones, and grow sub-tropicals
but none in New Orleans
So i know i will have losses.
We just had the coldest day of the last 10 years a few weeks ago
and i lost a few mango, black sapote, neem, eggfruit and others.
but i am not detterred.
several plants came through. Even a Baobob in a container.
i have LOTS of mustard, gynura and other small plants that grow fast
and i also often use as mulch.
i dont ever seeing it as totally hands off
even in 20 years when the mulberry, babob, longan, Inga, white sapote
and other trees are 50ft tall or more, and shade the whole system
i would still want to prune them, and prune shade-tollerant plants under them.
Call it a food forest,
permaculture, or just a backyard with a lot of plants
i dont really care.
it is what it is...
