Hi, I am a first time user here, looking for help! First of all, I live just outside St. John's, Newfoundland - as far East as you can get! I have a very small blue spruce (or it used to be). We've moved and I moved it with me, however, now it is just another GREEN spruce. What can I use to turn it back to BLUE!!!
The coloring is caused by the waxy coating on the needles. Elsewhere I have seen it claimed that fertilizing can cause a faltering one to appear more blue, because its overall health (and appearance) has been improved. If you want to try this, sample your soil and have it tested first.
