One good practice by some farmers is to plant another genus, like apple after the plums or cherries, in an orchard, to avoid diseases and to use different nutrients.

That sounds great, Jen!
Do you think you could ask the city if you can catch a few? I am sure there is a market for this genetics, you could sell the fertilized eggs...
If I was in your country, I would try to get some.

The most common grafting techniques need the same diameter. This is especially the case with the newer grafting tools, like the omega grafting tool.

There are however many other techniques requiring a smaller scion than rootstock diameter.

As you now seem to master the principles of grafting with one technique, it is really easy to learn new ones. Just search for images for "grafting techniques", you will find many suited ones. https://duckduckgo.com/?t=ffab&q=grafting+techniques&iax=images&ia=images

Having grafted many things, but not yet persimmon, I cannot tell you what works well for persimmon, but you can specify that in your search, most techniques seem to have been used.

There is a lot of research on agroforesty in the tropics, you however have to use other terms for research:

I think that Tropical Homegardens is the term you are looking for.

Use that in google scholar or any other scientific repository, and you will find way too much information :-)

Hello fellow berry fan Emmett,
I avoid this problematic by bringing in cuttings of the berries I want. It has the advantage of being way cheaper, (usually free), but you might be a little bit later.
Good luck with your berries

I finally bought 2 of Lloyd Kahn's books from worldofbooks.com. They arrived within the announced time, and the condition was, as stated, very good. Although one had a cut in the cover.

Kate, I really like your approach of NOT going through affiliate links owned by Amazon. But to manually search for the books independently. Thanks, I pick it up!

Don't cut down your girdled trees yet! Maybe you can save them by bridge grafting: Below a video showing the process with apples

Aha, thanks, this name helped me. According to the link below:

M. indica is relatively distinct, combining a scabrous upper leaf surface with elongated styles which protrude from the fruit. The first character helps to differentiate it from M. alba, the second from M. nigra.

Hi,
I received a mulberry plant which is believed to be Morus rotundiloba "Mojo Berry". I see online that the species in from Thailand, the variety is a dwarf one, and that it has the same chromosome number as M. alba.

The person who gave the plant to me told me that the fruits are red. On the pictures online, it appears that "Mojo Berry" is black. Therefore I am unsure of what it is. Mislabeling happens quite often.

Anyone knows how to identify the mulberries at the species level? I only know that M. alba has long stems, while M. nigra has almost nonexistent stems on the fruit.

Thanks for all the feedback.
Jennie, what a bummer that bookfinder is owned by Amazon, and (almost) only redirects to Amazon. I checked for books I ordered in a local bookstore, they weren't listed...
