What is the shelf life of this product? If I use 1/2 gallon this year, will the other half be good next year?

Buy the concentrate and use as much as you need, then rinse out your sprayer, don't keep mixed product. We have saved the concentrate and used that year to year with no problem. Just keep it where it won't freeze and thaw. Last year was terrible for hydrangeas and even wilt pruf didn't save the buds when we had prolonged very cold weather early spring. Let's hope for a better year. Christine and Richard

It will definitely be good the following year provided you store it in a place where it can't freeze. Hope that helps.

check expiration date on container. My last container says 1-20-2016 so you should be good for at least a year.

This product doesn't have a shelf life that I'm aware of. The contents are under pressure. As long as the integrity of the container isn't compromised you should be good to go.

I'm not a seller, but a customer like you. That being said, I have used these products for a few years and have never had any problem with shelf life.

Where did you see that shelf life. When i read in to this product it said 20 year shelf if stored in right elements

my bottle says, "best by 2/2016," which suggests that they recommend a 2-year shelf life

Use half save the rest in a reusable container and you should be good as long as the container is seal

The label says" keep product refrigerated and use within 2 months." It seems ok may be for a year. However, after reading the label, I am concerned about "Nitrogen-flushed to maintain freshness." I called the manufacture product department asking the toxicity of the nitrogen, they claim it is non-toxic but there is neither study nor authority to prove it. If you have nitrogen flushed toxicity information, let me know.

I'll have to modify my answer. I have a ten test kit but, again, the shelf life was well over 12 months.

It's recommended that you change out your reagents every year but I believe that can be extended if it's kept in a cool dark environment with the cap on tight. I will keep mine for 2 years and replace it.

The stated shelf life is 2 years, but given the packaging, I would confidently use this far beyond that as the other responders have indicated.

It varies on the bottles I've purchased - on avaerage I would say it is about a year from the date of purchase. However, I have used this stuff with excellent results up to a year and half after the expiration date when properly stored.

I'm sorry, I bought this a long time ago. I don't remember the shelf life. It was well sealed, so I doubt additional sealing would help.

1 bottle might last up to a year, but if you use it frequently, it won't. Probably the four bottles are more than enough for a year and a half so you won't have any problem with the expiry date.

Yes, at least 2 gallons. It is alright to purchase another gallon as this product will last in storage without degradation.

4 Years is the shelf life. It is unaffected by opening it and using some. If it takes you 4 years to use this product, you clearly do not go outside enough. Some people use it as a back up and I would suggest using it in that last year and replacing it.
