Last year I bought the 360 day version of nutricote. I was and still am very pleased with that particular product. I have waited for months for it to be “in stock”. I finally purchased this product, although I wanted the 360 day version. I am sure this is an excellent product, but I will have to use it later so that it lasts through the summer months (bloom season-April through September for Daylilies in Texas). The reason for the 4 stars has nothing to do with the product itself, but rather for the lack of restocking the 360 day version. Nutricote is the best product of its kind on the market. It’s not easy to find for public consumption. I am sure this product will not disappoint!!!
