Grafting climate question

[Redpaws]

If you graft any tropical fruit tree onto a non-tropical fruit tree, can you avoid death by cold temps?
Example: Grafting mango cuttings onto a pear tree. Will this allow the mango branches to survive sub-zero winters, and then be able to grow fruits during summers? Or will the mango grafts still permanently die after temps hits freezing?

Been wanting to get some tropical fruits for my base, but that'd be a very long journey, and a very long time to find out if all the grafted cuttings permanently dies in the winter or not.

...Or have I misunderstood completely, and the die-below temperatures only applies to the growing stages of fruit trees, but not to fully grown trees? Could I plant a mango tree in a temperate area in very late spring, and as long as it grows before fall, it'll survive winters?

I don't see any temperature requirements for the grafting process itself on the wiki, but for several reasons grafts should be somewhat in the same temperature zones as their host.

https://wiki.vintagestory.at/Fruit_tree/en#Grafting_Fruit_Trees

Depending on the trees you want to use in combination with the temperature ranges around your home, you might get away with planting/grafting them in greenhouses, though.

The main goal/answer is if I CAN have tropical trees/fruits growing in a place that can go down to -15C during winters, or if even adult fruit trees would die off entirely. Only being able to get fruit during summers is perfectly fine. The wiki isn't clear if the die-off temperatures only applies to growing trees, or if it also applies to mature trees. Tried searching around for an answer, but I just get a flood of wholly unrelated results.

I am gonna test this real quick, since if have the same question.

so my test result, "Cannot mix decidious with evergreen trees" was the message from the game.

That's good to know! What about fully mature fruit trees? Do those also die to the cold? Or could I grow an evergreen tree, in a place that experiences freezing temperatures at winters, if I time it right?

According to the wiki, it sounds like even adult trees die when it’s too cold. There’s always a chance it’s wrong, but I wouldn’t count on it.

”When planting a fruit tree cutting directly in the ground, each of the cuttings has a 40% chance to take root. However, if they are planted outside of their temperature comfort zone, where winter temperatures fall below their die-below temperature, they will not take root no matter what - or they might grow up only to die during the winter.”

If you’re dead set on having different fruit trees at your base, try what this post recommends to edit the cold resistance/die below temperatures of fruit trees.
