The Tropical Fruit Forum

  I think I would be more worried that it won't get enough sun.

Yes, but it depends on the orientation of the house and resulting shade.
If this is on the north side of a house you should only consider shade loving plants. Most annuals love more light. Most fruit trees unless they are shade lovers will grow tall and spindly in such conditions trying to find light.
If you want one tree plant it on the extreme outer end and it will grow outwards towards the light you could plant shade lovers back of it. I know of a mango planted directly under a vigorous oak tree. One branch grew horizontal and found it's way out to the sun, then grew up and is making some fruit. So if a tree can find sun it can have it's roots in shade. Here it is:

Congratulations growing any mango so far out of zone is an accomplishment with many odds against you. The next challenge will be to overwinter it.

These nanas have started to get pretty big since I first stared this thread and are starting to lean a bit.

Does anyone have a suggestion or idea on how to anchor them to the cinderblock wall? Thanks.

I knew they would lean outwards.
Looks good with no need to secure them since they are between the wood and wall. Let them lean out they will touch the wood and be supported.

Here’s the progress so far:

These photo say I need permission to see. Maybe you need to set them to public?

I have grown cashew in the tropics and they are very tolerant of sun. The large reserves in the seed gives them strong growth at first. They grow in very poor soil but can't stand any waterlogging or poor drainage. I grew in #10 cans in a very gritty mix with some compost but mostly quarry fines with almost perfect drainage. Some rock quarries have little use for the fines if you know where an old quarry is they may have piles of it or it may be for sale.
which is coarser than sand

I ran across this discussion of Dorian and if anyone wants to geek out he shows a lot of details.

What would be the best way to combine these 4 species mono cropping patches within the food forest?
Could I intercrop between them (for example macadamia and coffee), and with other species (such as bananas, etc)? What would be the best tree spacing for these crops? Any suggested varieties for these species?

There are advantages to keeping similar trees together, but maybe advantages to spreading them out.
Yes you could intercrop between larger trees but usually intercrops are chosen as short term like bananas, or shade lovers like coffee.
Your Macadamia would be large in size trees and very long lived so they wouldn't fit into an intercrop scheme as short term or shade lover.
Avocado might be able to tolerate some limited shade and definitely enjoys wind protection.
Tree spacing really depends on variety and I would suggest only planting varieties proven in successful your climate.

Looking at your questions it seems you would benefit from learning the permaculture design process. I did take a class and found it useful because it systematizes the assessment of a site to take account of all the environmental factors, needs and goals, stacking multiple functions in the same space over time, among others. Doing this takes lots of on site observation, researching local knowledge, and developing solutions to problems. You start out generalizing and get more specific as you go along but by breaking down the elements into manageable parts you'll find that many decisions which once appear complicated get simplified. Sometimes constraints end up leading you towards solutions which weren't clear at first.

You should at least look at your most significant crops, mango, avocado, coffee and Macadamia and dive deep into each one. Learn where they evolved, which management of each works best in real life in the Azores. Look at a young, medium and mature planting of each one locally to see what worked and what didn't(always ask the grower what mistakes he made!). The site appears to have established grass. Grass can be good it is natures blanket over soil when cut regularly but that is more suited to ordinary orchard management. A classic food forest is a soil building system which uses the widest variety of support species spaced out over time emulating the succession of species building a self sustaining forest. Yes you can have a blend of both but the established grass can be a hindrance to management or it could be an assest. It would really be beneficial if you could actually go and see the process of a sucessful project likeyou propose in your zone.

This doesn't get into detail but is the best short explanation of what a food forest is intended to be that I know of.

i still think your calculations in hectares are wrong and the fires in Brasil are probably 4-5 times bigger.

My calculations are accurate, and based on the figures quoted in the newspaper, there is a big difference in the case of Bolvia.

I'm not the only one asking why Bolivia is getting a "pass". It turns out that the socialist-dictator-to-be Evo Morales signed a decree legalizing the burning of land in Beni and Santa Clara and others in Latin America are calling him out.

Evo Morales legalized agrarian burning
A month before the fires, on July 9, Bolivian President Evo Morales approved the modification of the “Supreme Decree (DS) 26075” through the promulgation of DS 3973, which allows burning of permanent forest production lands.

They all obediently stand and applaud as Morales signs the order:

"A team of University of Florida biologists found, for example, that it was almost impossible to establish the Brazilian pepper in an undisturbed forest."

Humans have damaged the landscape so much.

That was believed true in 1982 by the New York Times.

Brazilian Pepper even invades and dominates mangroves. To get it out then the mangroves are destroyed. I actually do call it Satanwood. Luckily I'm not allergic and was able to tolerate running it through a chipper. Here I was yanking them out with a small tractor. If you cut them high and use that as a lever they have shallow root systems and can be pulled over in sandy soil. The 12 inch diameter monster at left side of the screen required an excavator.

And there is another aspect when calling socialist vs capitalists.The socialists did manny mistakes ,but they have the power to revert them back as you see in China right now,whereas the capitalists take the monney,destroy the land and they cant do nothing to restore it after because there is no profit in doing so.

Actually, since forests produce wood which is a renewable resource they are quite profitable and are increasing in the USA, which did significantly deforest and is a capitalist country. My family has operated a sustainable timber farm in Arkansas for over 100 years and 4 generations

This grafted variety is known in the area and was propagated by the nursery which used to own my place. Does anyone have experience with it? I am waiting for this to ripen.

I've had some luck getting Acerola from cuttings but tented the cuttings and had them in full shade a log time. Probably less than 50% success. Agree with Peanut Butter Fruit, seeds are large, have a lot of energy. They respond very well to tipping and every time the shoots grow 3-4 leaf pairs I tip them and get 2 branches. These bear on branch tips so you don't want a tall tree but the most multi-branched compact shrub you can get.

I stumped them and they have quickly sprouted. Some sprouts are getting big enough to start topworking, and I plan to prepare scion wood by tipping and defoliating to stimulate dormant buds. I have access to several mature trees to get the material.
