Called stone rafting
See this video, one of several on youtube.

A forum member, Simon, undertook a study with double stone grafts in California.  Posted a lot of good info.  I believe his experience in CA was that the plant tried to flower and fruit way to young due to conditions in CA.  I am sure you can find the post if you search for "double stone" on the forum.
NOTE: the one that I tought it was psidium australe is in fact an hybrid, maybe P. guineense x P. grandifolium (Leslie Landrum told me that): frost resistance is the same and the species grows in the same region as psidium australe. A rare one! Pulp is firmer / crunchier, less gelatinous than that of the common psidium guineense and the taste is sweeter. The plant seems very similar to what you see on the internet in terms of psidium grandifolium.

Yes it is a low chill type. The new leaves are getting it maybe a week or so after forming, whenever the leaf almost gets to its full size. Every leaf on the tree has it. Unless it is super new growth.
Small scions and depends on the cultivar. Monoembryonic seedlings are generally sufficiently thick. For polyembryonic seedlings (which are thinner), there is a technique where one tips the scion donor tree before planting the seed to produce thin shoots. I think the trick is to tip just after a flush point / node (vs below it), which produces a large amount of thin shoots.

When I've grafted recently sprouted seedlings like this, I've always favored monoembryonic seedlings. I know nurseries like turpentine (which is polyembryonic), but I've had excellent success with monoembryonic seedlings, such as glenn.

Mango seedling can be grafted 3 weeks after sprouting (while still tender and "red stage") with high rate of success. The seed generally has a store of energy for 2 flushes, so if you can graft on the first flush, there is still enough energy to push the scion to a full flush. That flush is then used to provide energy to the tree.

Just wondering about how low it takes for Turpentine seeds to grow to 3 gallon grafting size?

Single bud or small scions?  It seems like the seedli gs are really small to be grafting to at that point no?  Need steady hands?
We have an Asian (Vietnamese?) lady that will come each year and ask to buy the entire crop of NDMs.

Tropical Fruit Discussion / Namwa banana Mosaic virus?

Hi. I am new to growing bananas and just bought this Namwa.  The new leaves have this pattern in them that seem to be Mosaic virus. Can anyone confirm this? Also, if this is it, how serious is it? I have a couple of other varieties planted nearby as well. Thanks for any help. I am in Homestead, FL

If you get the seed permit don't the seeds need to be shipped without dirt of any
kind? If the seeds take 1-2 months to leave their country like Brazil how would they
stay moist and not desiccate? So many seeds would not make the trip without moist substrate???

Do you have a low chill type? Are the old leaves getting this before they drop or new leaves?
