Jack's Professional 15-10-30 Pot Mum Fertilizer - 25 lb

High-Potassium Finishing Nutrition for Flowering Crops - 25 lb

Late in production, too much vegetative growth can leave you with weak stems and uneven flowering. This 15-10-30 formula uses a 1:2 nitrogen-to-potassium ratio to support stem strength, flower development and controlled growth through the final stages. It also carries a traditional general-purpose micronutrient package, so you do not need to source a separate basic micronutrient blend.

The 25 lb unit suits growers who feed regularly through a production cycle, from serious home gardeners with several containers to greenhouse operations that want a steady supply of a finishing fertilizer.
