because it has the name of Japanese maranon? since it does not resemble the classic maranon at all ... what is the origin of the name?
Thank you
Hi Gittel.
I could not tell you. The common or popular names are given by the people, depending on their culture, tradition and / or the characteristics or uses that are given to the plant.
Unlike the scientists, that each plant only has one and you can know the origin and the meaning that it has by studying the taxonomy, this does not happen with the common names.
Regards!
I have a tree that is 2 meters tall and in these warm months the leaves are turning yellow. What could it be? Could someone tell me if this is normal?
Hi Rudy.
It could be because it is too hot, or because the soil does not have a low pH (acidic). It is a tree that does not like extreme heat too much; in fact, for it to be healthy it is recommended that it does not exceed 35ºC. But also, as I say, it could be that the soil is not suitable. In any case, it will be good to fertilize it with a fertilizer for acid plants. Of course, you should follow the instructions on the package.
A greeting.
