I have read on these newsgroups that one teaspoon of Epsom salt mixed in a
gallon of water will help blue evergreens to be extra blue. I apply the
teaspoon of Epsom salt dissolved in a gallon of water, then I water
generously. It does work, they are nice and blue.

My question is how often can I apply the Epsom salts to small (young) blue
spruce bushes without overdoing it?

Couple times a year. Magnesium is good for most plants, just like
iron is good for animals. Without small amounts, living things die.
