Thanks for the info.

One more question, how can this be a fertilizer burn problem and just now showing up?

Read the label on the fertilizer bag. The fertilizer dosen't go away quickly when it is poured out in the concentration that you spread. It can take a year for fertilizer to leech through the soil. At this time I would think your area is almost toxic... Just like trying to eat a fried turkey, prime rib, 10 bag of potatoes and all the trimmings in a day... Too much nutrient can be almost more of a problem than not enough. The seedling can burn up...

Yea, that makes sense.
