Hello; the best protection against pests is general good health. Most
primroses need full sun in the spring for maximum vigor. I have grown them
in areas which were primarily shady year-round, but they were notably less
vigorous (grew slowly, wilted easily, attracted bugs, etc.) than others
planted in sunny spring/shady summer sites. Also, I do not know how
thickly mulched they were - since most are evergreen, you have to be
careful not to suffocate them. I would think the fir branches would be OK
if placed lightly over the primroses.
Diazinon will kill maggots of most kinds, if you don't object to such a
strong poison.
