What is the shelf life of Bora-Care once it is mixed?

I mixed a ratio of 1:1 Bora-Care with water, but I had a half gallon left over. How can I store the extra mix of Bora-Care solution? How long can I store it for before using it again?


Any left over Bora-Care can not be stored. Bora-Care that is left for more than a few hours after it has been diluted will start to separate from the water and will be impossible to get back into a proper diluted form. You should dump any extra mixture right up against the foundation of your house (away from any plants as borates will kill plants). Be sure to thoroughly rinse your sprayer to avoid leaving any Bora-Care residue that can potentially clog the nozzle or hose.
