You can control that by pruning. Here's how:

I bought a weeping cherry tree 2 summers ago, last summer a branch started growing straight up in the air. I read your article on what to do and it said not to prune it as it will eventually weep. I didn't think it was a grafted tree. The branch is thicker now and taller and is not showing any signs of weeping. We will prune it either way this fall. We looked for a graft knot and didn't see one that we know of. Could the branch have grown out of this knot? The close up picture is of the branch growing out of the tree. The last picture is the other side of the tree, not sure of that looks like a graft knot or not.
The graft should look like a knot in the wood.

I picked up the wrong can, and sprayed the young tree’s branches with Cutter Backwoods. In the morning, I did douse the tree with water (less than 12 hours later), but all of the leaves are brown and wilted. Ugh! Help!
You will have to treat this as if it were sprayed with a pesticide. This article will help you begin to correct the problem, although it is common for a tree to die when this happens: https://www.gardeningknowhow.com/plant-problems/environmental/herbicide-plant-damage.htm
I've had a weeping cherry tree for a few years. The limbs are strong and long but the trunk just isn't getting taller. The limbs are dragging the ground. I don't know if this thing is going to grow or not. The trunk also looks like it is branched out like limbs, instead of one trunk? When it was just a twig, rabbits chewed it off so I don't know if that has anything to do with it. Does it have a chance or should I start over?
The rabbit may have destroyed the graft. At a minimum, it ruined the central trunk and spurred sprouting from below the graft called suckers. Read the following article and decide whether you want to try to train what is left or start over. https://www.gardeningknowhow.com/ornamental/trees/weeping-cherry/cherry-tree-no-longer-weeps.htm
We planted this weeping cherry 2 years ago. Last year it was fine. This year, it bloomed beautifully in the spring, but in early July the leaves started wilting and developed black spots (see attached picture). The bark looks fine, but a couple of long branch ends look dead. From this description and picture, do you have an idea if it can be saved?
It appears to have received a little too much water, leading to a fungal infection. You will want to treat the tree itself with a fungicide. This article will help: https://www.gardeningknowhow.com/garden-how-to/info/using-fungicides-in-garden.htm
My personal recommendation is to use DOLMITIC LIME and WETTABLE SULFUR. Just a cup of Dolomite lime and a teaspoon of wettable sulfur scattered around the root area will help, drastically. Do this once per year, and as a spot treatment.

Is human urine good for lemon trees?
This article will help you with your cherry tree: https://www.gardeningknowhow.com/edible/fruits/cherry/when-to-fertilize-cherry-trees.htm
Human urine, unlike most other mammals, does not break down into ammonia, fully, inside the body. This means that is contains a fair bit of urea, which the tree will have a hard time breaking down without the help of specialized bacteria. They may or may not be present in the soil.
What you may notice when you start using human urine is leaves turning yellow, pH dip WAY downward, and lockouts of potassium, phosphorus, magnesium, and calcium.
If you ferment it with hay, then compost, you will have a nutrient rich solution. I'm afraid, before that, it is not going to be very good for your tree.
One more thing to consider with human urine is metabolites that don't get processed fully, or remain in human urine. Some things that we consume are quite toxic, and even more so to plants. Feeding them our urine will be a death sentence to the tree without proper preparation.

The tree was just planted in August; this just started happening.
Without seeing the tree, it is hard to say for certain. My best guess will be a fungal infection. This can happen when the tree is planted in heat, and gets watered just a little too much in compensation.
Many times, the winter should take care of it. Freezing temperatures can help drastically. I would also treat with a fungicide to be sure. This article will give you more information: https://www.gardeningknowhow.com/garden-how-to/info/using-fungicides-in-garden.htm
