Am I able to use pig manure on my garden straight up, as it's full of garden worms, so I thought it must be okay. I have mixed it with soil and some bark to try to get some hardwood cuttings to take.

We would not recommend using manure that has not been composted on the garden, especially from animals that are not vegetarian. Because pigs are omnivorous and eat meat, they are more likely to carry pathogens in their manure that can make people sick. Allow the manure to "cure" away from the garden for 6 - 12 months, then spread it on the garden.
However, if you are certain they are only fed non-meat, you can reduce the amount of time the manure sits, but it still needs a little time to "cool" down, as they say. Fresh manure has very high nitrogen which can burn plants. With the worms, that will certainly help to reduce the time, but I would still recommend that you let it sit away from the garden for a few months, maybe 2-3 months, so that the nitrogen mellows.
