Due to all the leaves (tons) I have added to this particular area, I can't imagine it being short any minerals or potassium. However, due to the very wet conditions and the large amounts of rain we have had over the past several months (plus all the tons or high carbon organic material) I can be almost certain I am very short in nitrogen here. Yes, a soil test and a plant test would be best (I agree) but right now in this location I need to get them fertilized. I should have done the tests earlier (maybe next year)?
