You have to read the bag carefully. http://www.seedland.com/mm5/merchan...roduct_Code=FERT-423403-15&Category_Code=fert The Pennington 29-0-5 "slow release" may be within the law--but the label is intended to fool you. It contains 6.8 percent coated slow release nitrogen. And sometimes due to rough handling--some of the coated granules are already cracked--and thereby useless as coated fertilizer. Consider Scotts to be the highest price, and highest quality (at consumer outlets). Applied now, most of that product would be used up and absorbed by the roots in the fall.
