Do not store diluted fertilizer.House Plants: Use 1 tablespoon per gallon of water. Feed every 2-3 weeks. Do not over water.Outdoor Plants: Use 1/8 Cup (1 fl. Oz.- 1:128) pergallon of water.

**Q: what is the shelf life**
A: From the manufacturer's website FAQ - Our liquid fertilizers have an indefinite shelf-life, until water is added. Always shake well before use. The longer the product is stored, the better you'll have to shake it up.

**Q: I like the looks of the reviews but, the smell wouldn't bother me if it works, will it attract bears and raccoons?**
A: This is the hydrolyzed fish and seaweed Mix. It doesn't smell bad when you first mix it up, just be sure to use it all at one time. I mean make small batches like a gallon at a time or quart. Use it all don't let it sit in a container. It then will stink! I haven't had any problems with wildlife. The only thing that might attract is flies.

**Q: Where does the fish come from? I am trying to avoid pacific fish because of the Japanese power plant melt-down**
A: This is what it says on the bottle and their website:  "Neptune's Harvest is a division of Ocean Crest Seafoods Inc., established in 1965 as a wholesale fish and seafood company. Still today, our Neptune's Harvest Organic Fertilizer gets made from fresh caught North Atlantic fish right on the docks of Gloucester, MA. Unlike a fish emulsion,our fertilizers are produced using a unique cold process "without cooking out all the good stuff". Best of all, it works great on everything that grows!"So it's a Massachusetts fishing industry byproduct! :)
