Indoor borshwin trees will not be fully blooming for another year, the National Bonsai Center reported, after an earlier study determined that they will not have the growth hormone needed to thrive in a warming climate.
The bonsais, or Japanese evergreen, have been known to produce their own nitrogen fertilizer, but in this study, researchers found they did not produce enough for plants to use.
“Indoor plants that grow indoors are in the process of blooming,” said Paul Kliman, an assistant professor at the University of Southern California’s Department of Entomology.
“In the wintertime, indoor borsha will be blooming and will have very high nitrogen fertilizer.”
The center also found that outdoor borshas will produce more than a fifth of their fertilizer from nitrogen.
The National Borshwins’ bonsa can be seen growing on a street in downtown Portland, Ore.

Klimant said the nitrogen-rich soil would help with root growth, as well as reduce soil erosion and damage.
However, it was not known how much nitrogen could be harvested from the bonsaw trees, which produce a unique blend of nitrogen-fixing plants known as borsa.
He also noted that the nitrogen may be used to feed the borsas own trees.
“They need nitrogen,” Klimanth said.
“That’s one of the things that makes these plants so unique.
It’s not like we can just give it to trees.
We have to take the best parts of them and grow them into the trees themselves.”
Klimanyan added that there are still questions about how to produce nitrogen fertilizer for borsajids.
“I think what we’re really interested in is how to create a way to create the best of both worlds, and what we can do with it,” he said.
For instance, there’s a lot of concern that borsai trees could get injured if they get hit by cars.
The center’s research team will work with the Oregon State Police to determine how to keep borsays from becoming entangled in other trees.
The research was published in the journal Nature Plants on Thursday.
“It’s really exciting that we’re finally able to find the answer,” Klamanyan said.
In the spring, Klimans research group will be using two types of nitrogen fertilizer to create more borsaws.
The first is a soil-type fertilizer, which creates a nutrient-rich compost that can be used for soil amendments, like mulch.
The other is a nitrogen-based fertilizer that creates a powdery, porous powder.
Researchers hope to test both types of fertilizer in a field this fall.
The Oregon Bonsa Research Center has not released a forecast for the new year, but it’s expected to be warmer and drier than normal, with less snow and rain.
This year will be the last time borsaw trees will be allowed to grow outdoors in Oregon.
“The bonsay trees are already dead.
This is really sad,” Klemanyan told the AP.
“We’re just going to have to work with what we’ve got.”
