To those who care, this fertilizer uses a plastic shell on the fertilizer to control the release. That means that after a while there will be empty plastic left in your pots and garden, neither of which is great for plants or for animals that might come in contact with your pants.

Just food for thought for those that prefer not to contribute to more plastic in the environment.

A soybean derived polymeric resin isn't the same as a synthetic plastics

No need for fake news. It's not plastic it is a biodegradable polymer resin.

Thanks for letting us know. I was planning on using this in a vegetable garden but don't want plastics in it

Glad to provide helpful information! It's not uncommon for time release fertilizers to use plastic and this is far from the only brand to do so.

If you're interested in avoiding plastics in your fertilizer, Jobe's, Down to Earth and similar organic brands don't use them. There's obvious trade offs going with an organic fertilizer vs synthetic options (cost, shelf life, etc.), but I feel like a lot of gardeners would hesitate to knowingly add plastics to their soil.

I see no coupon or deal.
It is $19.05 for me.

But then I have also bought it twice before in the last year, so maybe no deal for me from Amazon?

I had to logout of Amazon. Open above, pick the coupon and discount and then login again to see the deal and discount and make it work.

Goes to show Amazon won't ever let you see the best deal or price on while logged in (based on your shopping history).

Not sure where you found that their polymer is derived from soy beans because I found it is made in part from dicyclopentadiene.

"The coating technology in Osmocote (OM Scotts Company, Marysville, OH) was developed in the 1960s, and this coating is classified as a polymeric resin. The coating process involves coating a soluble fertilizer core with a thermoset copolymer of dicyclopentadiene and a glycerol ester (linseed oil) dissolved in an aliphatic hydrocarbon solvent."

Dicyclopentadiene in the environment is also harmful once it enters the environment, often cause disruption to the reproductive process of animals.

It's not a soybean derived polymer. In fact, it's a copolymer with natural linseed oil and a synthetic dicyclopentadiene that is absolutely harmful to the environment.

I'm not here to say that using a small amount of the fertilizer is going to kill all life on earth. I just think there's value in knowing what people are putting in their gardens.

We use this on Hosta and Daylilies, works fantastic. Also use it on our container garden. This goes on sale about once a year. Still have some left from last year or I would be in for a few bags. Thanks OP!
