Apple is Crispin have no idea how to reduce image size
Typically, pests like this are controlled with Bacillus thuringiensis. This will target the larva, and ultimately, take out the population.

Hi my mother has a vigorous vine in her garden. I don't know what it is. But it has wrapped itself around her apple tree and is shockingly a part of it now. I can cut the vine at base where it grows from the soil. But as the vine is now part of the tree, will it live off the tree now, if I cut the vine at base? Like a parasite? I don't know what the vine is. It's very twisty and gets everywhere....thanks.
Before deciding to do anything, I would first get several pictures & samples of the vine and its blooms and take them to a local garden center for identification. I normally try to keep all plant growth away from my apple trees.
I have a filbert tree that has the blight, several other trees already died and were removed. Today I think I saw the familiar bubbles under the bark on my apple tree. Is it possible that apple trees get it too? And will it kill them also? Is there anything I can do?
This research says it only affects filbert-type trees. https://hort.extension.wisc.edu/articles/eastern-filbert-blight/
Here's our GKH article on how to treat the disease:

But apple have their own blights like fire blight and Southern blight.

My baking apple tree ,for the last two years hasn't produced many fruits, and what few appeared,were only the size of golf balls,the same with my two eating apples,they are all growing in largetubs,well watered and fed,have had them maybe between five and fifteen years,please can you help?... thank you .
I suspect the soil has not been changed or topdressed for a while. Trees in containers need compost added as a side dressing to help replenish the soil. It's also possible the tree is root bound and unable to take up nutrients.
Check the tree for pests as well. Poor pollination could also result in small apples.
It also could be the tree needs pruning.

I ordered rootstock to propagate more apple trees at my home and was wondering when should I plant the rootstock in pots? Do I plant them right away when temperatures are still below freezing at night or wait until the end of April? I live in zone 4 Minnesota.
If you are planting in container, then I would advise planting immediately. You will want to keep these inside for the first year to let them get established before planting out in spring. This will give them a drastic head start.
Here is a collection of articles that will help with apple care:
How much cost will come , how much water required fro this project. I am planing to grow 30 tree for apple 25 tree for peach & 20 tree for pomegranate.
This is going to be a lot of information- Much more than I could put, here. I can point you to some resources that will be helpful, and more thorough, than I can be in this instance.
