Hello everyone! This is my first post on here and I am a pretty new bonsai grower. I have some Trident Maples that are giving me some trouble, looking for a friend here.
I keep them outside on my deck during the day and in the shade when its hot and bring them inside at night. I have been trying not to let them dry out to much. My medium is a mix of coir, perlite, vermiculite. Have been fertilizing every ten days or so. I have let off that since they have been deformed the past few weeks.

I added attachments can people see them?

Plants hate to be treated like this. Give them one spot and leave them there. Tridents are hardy. Ensuring they are watered and not in full hot wind exposure they can take most normal summer temperature ranges (say, 20-35 degrees).

So it is best to either leave them outside or inside full time? What time should I bring them in so they don't freeze?

Outside all the time. Never inside. If you live in a place with particullary hard winters store the tree in a cold but protected place in winter.

There is a common misconception that it hurts the trees to be outside in the winter. Every year I have to tell my wife that I am going to leave them outside. Every year.

The woods are full of trees that live outside all winter. They like it and have to have it. Their genomes expect a length of time not growing, resting.

You do want to protect just a little bit. Trees in the forest have their roots stuck in a huge heat sink and the roots don't want real fast change from way above freezing to way below. If a cold snap is coming up, don't leave them on the plant stand, but put them down on the ground. If you have pretty harsh winters, maybe put them in an unheated storage shed. But, let them have the environment they evolved in.

One way to protect the roots from quick changes in temperature is to dig the entire rootsystem with or without pot into the ground during winter. A quite common approach were i live in Sweden.

Myself, I have an unheated greenhouse where I store all my trees in winter. Some digged down in the growing bed and some on the concrete floor.

In fall I move my stands into the garage for maintenance, painting and storage. My trees are pushed together against a wall on the ground. Out of most common wind and out of sun.

In my garden I do not protect most trees (Juniper, beech, maples, syringia, larch, yew) for occasional deep frosts (-20C ).

What seems to be worse on my trees is late March/early April when we get a killer frost. Trees start to leaf out here in late January, and new growth starts in late February for almost everything, and then after a month of nowhere near freezing suddenly temps drop to 25F/-4C. I don't pay much attention to weather most of the winter but watch every day from mid March and move all the trees into the garage. It gets some heat from the house but I keep them close to the door. In the past I have lost trees and a lot of new growth.

Last year we had four days below freezing, lowest down to 27F/-3C during December and January. Then early April came with 22F/-6C three nights. Brutal.

Do you think the curling and dry leaves I have is from taking them inside and outside or could it be my water quality or watering habits?
