Most junipers don't expect a lot of fertilizer. I would go very carefully with the ammonium nitrate.

Problem with fertilising plants at any time of the year is that they tend to grow and young growth is susceptible to frost etc. Conifers grow better without adding fertiliser, they grow more compact and true.
