Hello, I’m new to bonsai and I’ve been trying to figure things out myself. Doing this has lead me to the fact that I can’t find much help if I don’t have a community to converse with.
So I have a few trees not sure what they are all named ( I grab trees from the woods n such on my travels. One of them is not doing so hot. I was hoping to train it until it could be wired.
I grabbed this long needle pine from North Carolina back in November. She came home back to NJ and was planted into soil so she could root. After a few months (around January) the weather got really bad and I was worried the roots would freeze in the pot. So I brought it inside to a cooler room in my home with ample light. It was doing ok until about a week ago when all the needles started to look dry and faded. Today I touched it and a few needles fell out. Upon light touch I pulled the rest.

By your description, it seems dead to me.
Can you grab some pictures as easily as you grab the trees from the woods?
Pictures help a lot.

Hi an welcome.

Sounds to me like you just killed your first pine.

Lesson to learn: There is the right time for everything. If you cannot protect from the frost, wait with collecting trees untill frost is pretty much gone.

Well I got 2 that day. This one was WAYY smaller tho and the roots barely came out with it.

Sorry I added the pictures but did not insert them

The pine is dead. The juniper will likelly follow if kept indoors. I can see snow outside. I would put juniper outside, taking the snow off the ground and put the pot on the ground. Then adding a thick layer of snow on top of it. This way it will stay moist and protected from deap frost.
