Does Thrive have a used by date?
Hi - Does Thrive have a "use by date" or does it deterioate with age - mine is now yellow in colour?
As long as the product is kept in a cool dust free environment it should not deteriorate and will be effective when using to fertilise plants. Thrive All Purpose Soluble Fertiliser is yellow in colour and the texture is a fine powder.
