This is so cool to have so many input on this issue. As you can see from my Martin Frobisher seedling how chlorotic looks.
I suspect that a disease like chlorosis can inhibit seed set and make the plant more susceptible to winter kill.

Warren, I took your advice and secured some some large wheat straw bales this fall. Next spring I'll apply 3 inches of
of straw to see if that remedies the yellowing of my roses.
I too,collect rain water in large vats for watering potted roses in the greenhouse. Our well water has too many chemicals like manganese. My Ag.Rep. told me I was literally poisoning my potted roses using wall water.
I water my baby seedlings in the basement in winter with melted snow.
