Making a Barocho on a Blossoming Tree in Nissan

The question is: Are we told to make the bracha in Nisan because that’s when the trees (generally) blossom, or is there a particular preference or obligation to make the bracha only in Nisan?
In most of the Northeastern US fruit trees blossom in Nisan. Even in an “early” year (like this year) by the last few days of Nisan it should have warmed up enough for the earliest blossoms to unfurl.
The question comes up in Eretz Israel where there are fruit bearing trees like almonds that bloom before Nisan, and in colder climates (or cold springs) where nothing blooms until Iyar.
Do you make the bracha early (Shvat, Adar) if you see a fruit tree blooming or is there a reason to wait until Nisan?
Did you miss your chance to make the bracha if Nisan ends and no blossoms opened yet, or can you make the bracha in Iyar?
What about the Southern Hemisphere where the seasons are all mixed up? (Hint: there are all kinds of shaylos that come up there, and there are different paths in Halacha followed in different places, Argentina, South Africa, Australia, etc according to the poskim who determined Halacha in each place.)
I’m not going to offer any answers. If I tell you all what my understanding is I just know the complaints will appear like blossoms on a plum tree in Nisan.

May I say a blessing on a fruit tree whose fruit has been pruned?

For example, a coconut tree that’s had all of its coconuts removed?

Thank you

Lightbrite, the blessing is made when you see the blossoms. A tree with fruit or after the fruit is harvested doesn’t fit the bill. It’s questionable if the closed flower buds are good, better if you can see the petals of an open blossom.
I have no idea how the blossom of the coconut palm looks. Maybe they’re too high up to notice? All fruits start with a blossom but some are small and insignificant, and some are showy. Some flowering trees that are covered with blossoms in the spring don’t bear edible fruit. The Bracha must be made on the flowers of a tree that bears fruit, like apple, cherry, peach, plum, quince, citrus.
If you’re in the Northern hemisphere I’m sure your search will produce results soon. Let us know what you found!
By the way, this Bracha is made only once a year, every spring, preferably Nisan if that works where you are.

Can you make the same Bracha in a Toyota?

You can not say bracha in a Mazda as it is AZ. That is Avoda Zara. You also can’t say bracha over other AZ – Astra Zenica – as astra means “star” and Zenica means nothing, so you don’t want to say brocha over Avoda Zara or over nothing (as in “thanks you for nothing”). It also has questionable performance, so no bracha b’sofek. On a plus side, seems like Wallenbergs still have a share in the company.

other questionable places for bracha, ask your posek –
Subaru (stars, Pleiades), Yugo (sakana), Ford (anti-semite), VW (ditto) esp Rabbit and Beetle – not kosher. Tesla – drives by itself, no bracha required

@huju, then he asks a Open Orthodox rabbi and he say responds, its a svek svaka one side its named after a animal, one the other hand Tata Motors did some enviormental damage and driving a car causes global warming therefore make a brocha without using the shem

I think it’s ליהנות. Not להנות.
