Hi there!
I am growing a Pinus Aristata from a seed. It was doing super good until a couple days ago when the vibrant green turn to almost brown. It was receiving direct sunlight for relatively long hours.

Is there a way to get its vibrant green back?

Do you have a picture from the seedling as it looks now?

By the way, I am sure you know but.. ines should be outside.

Thanks for your reply.
I fact, I didn't know they should be outside. It is my first try so thank you for pointing that out. The seedling is still small, though, and it is windy outside so I am not sure if I can do that.

I am attaching some photos for the seedling now.

Thanks again for the help.

Well, its fairly easy: if you dont place it outside it will die!
sarcastic mode on " i am not aware of seedlings that migrate inside their first years..." sarcastic mode out.
I have no idea where the idea comes from that trees can survive inside, let alone saplings or seedlings...They need to be outside to survive, our homes are a hostile environment for them ( dry/hot/always the same temp).
Btw, you do know that there will not grow a bonsai tree out of that seedling but a normal tree?

The seedling looks fine. As the seedling matures, the stem turns woody. This includes a change of colour: it will become brown

That's relieving!! Thanks!

Why is this? sorry if I'm being naïve but you can google many images of Pinus Aristata bonsai trees.

Of course there are...
And i will say it again: there will not grow a bonsai out of that seedling but a normal tree. Bonsai is not a tree species nor do they grow under normal circumstances into a small tree that fits in a pot. Bonsai are made by man through the use of a lot of techniques. So bonsai seed does not exist, out of a seed of a bonsai tree will grow a normal tree if left untouched

No one mentioned 'bonsai seeds'

... then replace bonsai seed by seedling or sapling, or whatever young plant you want. Point is that every plant will take its normal full grown shape and size if left untouched.
