Mites can always be a problem and Eric is right to look for them. I usually see browning from the interior towards the exterior when spider mites are present.

I think you problem more likely is due to the "dry March" you described. Dry soils with freezing temperatures can burn even the most cold hardy plants.

Dry soils combined with salty, man made fertilizers will burn plants every time.

Never fertilize a dry plant. Get away from any kind of product that promises a miracle.

Don't acidify your soil without first doing a soil test to see if its necessary. Check with you ag. extension agent to see if altering the pH is necessary or even feasible in your area.
