As a shrub, you would think I would know. Oddly enough, steak and whiskey doesn't work for my plants.
I have ligustrums that I'm trying to fertilize.

My understanding is that for ligustrums, they will take a pound of nitrogen, two or three times a year, such as March, May, and July.
My questions are pertaining to the applications.
Can I put the fertilizer over the mulch or do I need to scrape back the mulch, apply fertilizer, water-in, and then reapply the mulch?
Do I need to use a slow release fertilizer, and if so are talking organic or something like PCU/SCU, or can I get away with an all purpose or ammonium sulfate fast release? Lastly, do I need to apply any kind of micronutrient package? Thank you.
These were just planted Fall of 2017, so they are less than a year old, in terms of being transplanted. There were 3-4 gallon sized plants if that gives any indication of actual age.
