    The general rule for newly planted trees (their first year) is to give them 10 gallons weekly per inch of trunk diameter at breast height. (DBH) Of course, severe heat or drying winds increase water needs. Sandy soils also increase water need. Water the same amount but twice weekly in sandy soil.

    Driving a nail into solid wood of a healthy, vigorous tree is not likely to cause immediate harm. But it's certainly not a good thing to do and it should be avoided if possible; there may be longer term negative consequences. There is potential for introducing pathogens. The degree of harm depends on the several factors, including the tree species and its ability to resist infection and decay.

    I will need to know the exact kind of shrub before I can give you good recommendations. Also, as we are based out of the US, as much about the climate of your area as you can give will help me to know what to do here as well. Photos will also help me to see what is going on.

    This appears more like insect damage; try looking under leaves to see if you can see a pest.
    I would however began treating with Neem Oil. Treat every 3 days for 2 weeks to start. This looks severe and you may need to treat through the season.

    This can be a rather difficult illness! When it keeps coming back, you will need a carefully planned attack method. The key will be persistence.

    This article will lay that out for you: https://www.gardeningknowhow.com/plant-problems/disease/black-knot-tree-disease.htm

    Promote a dominant central leader and prune for structural integrity. You can shorten lower branches, but leave some foliage to support photosynthesis and stability. Eventually you can remove these lower branches to achieve the clearance you need and desire.

    It will be difficult to pin down without a photo, but my best guess is something fungal. There are several options from here. My recommendations are as follows:

    About a CUP of DOLOMITIC LIME and a TEASPOON OF WETTABLE SULFUR per inch of tree caliper. So a 4 inch wide trunk would need about 4 handfuls of lime and 4 teaspoons of wettable sulfur scattered about away from the trunk. Feeder roots are further out than anchor roots.

    Your other defenses will include spray fungicides. This article will help: https://www.gardeningknowhow.com/garden-how-to/info/using-fungicides-in-garden.htm

    This article will help you to craft your own fungicides, should you choose this route: https://www.gardeningknowhow.com/garden-how-to/info/homemade-fungicide.htm
