I have recently left Southern California for Northern Idaho. Is it possible to grow dwarf lemon trees here? Could I leave outside during the spring and summers and bring inside ? Obviously they would be in pots that can be rolled in?
Yes, you can do this if you can keep them warm enough. Your zone is not a favorite of lemons, but with proper care you should be able to grow them. You are in zone 6; this article addresses growing them in zone 7, so you'll need to be extra cautious:

Here's an article that lists the fruits that grow best in your zone:

Some of the leaves look like there were holes eaten into them, but cant find any pests. Lemon tree is losing leaves that seem like they were dried out, but kept the soil well watered... Tips are turning brown on new leaves, and branches are getting droopy. I am having trouble figuring out what is wrong with it and would love some advice/opinion on how/if it can be saved. Thank you!
It's an interesting fact that overwatering can produce the same results as underwatering when it comes to leaves that look dried out and wilted. If your tree is getting too much water, the roots begin to drown and develop "root rot," which prevents the water from traveling up the trunk into the rest of the plant. If your soil isn't draining well, this may be your problem. As to the holes, there's clearly something munching on your plant. Try a few treatments with neem oil. Here are a few articles that should help:

There is a plant (weed?) growing right next to my potted Lemon Tree. Is it a weed? Photo's are attached. Thanks !
It looks like a tree sucker and should be removed. Always remove them as soon as you see them.

My lemon seedlings were thriving, but suddenly they're starting to turn brown. One has already died and I want to save the others. Currently they're all in one pot and until I noticed the first plant going brown, I'd kept them on a windowsill that got morning sun with a gallon plastic bag over them to create a greenhouse effect.
Let go of the plastic bag. Those are good for germinating seeds, but once the seeds have germinated, the bag is no longer needed. Now they need good air circulation to prevent fungal disease. Make sure they aren't being overwatered, also.

Which nutrient deficiency in this plant?
I bought my house 45 years ago and this lemon tree was in there and as big as it is now, bears fruit twice a year. Now I noticed that the trunk is cracking up and don't know why and what to do to prevent from spreading and or killing the tree. The tree leaves are healthy and bearing fruit. Thank you for your prompt attention Armen
Without knowing the age of the tree, you cannot know how long it has left to live. This tree is VERY aged. I would say that any cracking will be unavoidable, and expected, with an older specimen.
You can see this tree out, naturally, or you can help the structure in attempt to keep it alive for longer.
When building a brace, or putting any screws into the tree, just be sure that the screws are galvanized to avoid further damage.
Here is an article that will help you to give it the best care for the remainder of its life:
