Review: My lawn has never looked so good. - A landscaper suggested we get a good fertilizer for our centipede grass, so we chose this brand. This stuff is great! Our lawn has never been so lush. We had some bare spots where a tree fell over and destroyed an area and this fertilizer had the area filled in in two weeks.
Review: good for orchids - We bought this because a friend used to help his orchids to flower, really good product and you don't have to fertilize for a very long time, you only have to be aware of what concentrations of minerals you require or if its for flowers or other things like vegetables.
