I have used a number of Fertrell products obtained through my local dealer over the last six years including Holly Care, rock phosphate, greensand, lawn fertilizers, and kelp. I have been 100% satisfied with all of them. I recently moved to SC and have recommended to a local garden center that they carry Fertrell products.
Great company with represenitives around the country. They sell organically certified fertilizers and supplements for large scale growers and farmers. They are extremlly reasonable in price. They are also knowlegdable and willing to help you determine which fertilizers are best for your situation.
