Q.How would using my koi pond water affect the fertilization schedule this spring?
I have mugo and scott pine along with larch, juniper and boxwood.
Would fertilizing and watering with pond water be too much or would pond water be sufficient on its own?

I can't say with certainty whether your koi pond water would interfere with your fertilizing. This is a question for your local extension service. You may want to take a sample of the water in for testing when you ask this question.
