The fertilizer registration program ensures fertilizer products are in compliance with California Code of Regulations for fertilizer. Product labels are reviewed in the order they are submitted. It generally takes 60 to 90 days to complete a fertilizer registration. It is unlawful to sell an unregistered fertilizer product in California. To ensure your product fulfills registration, please begin the registration process 6 months in advance of planned date of first sale.
