## Questions & Answers

**Q: Can the 50# bag be spread on my lawn using a fertilizer spreader? (Not mixed with water; direct application)**
A: That would be most likely ineffective. The ratio is a tea spoon per gallon of water. If you tried spreading the product it would most likely just burn up your grass because a tea spoon of product isn't that much. Your best bet would be to get one of those nosal sprayers and connect that to the hose and mix up a teaspoon with a gallon and then spray over your yard for best results.

### ⭐⭐⭐⭐⭐ Sea Minerals 90 are a Gardener’s Dream Come Trus!
*by H***! on May 29, 2020*

Been wanting this for years for gardening. At 60, if I don’t start grabbing gears on dreams, that ship will sail. Bought a mobile and in a court on tiny lot. I still work, but most folks here are retired and on fixed incomes. I’m going to try and engineer the lowest cost, aesthetically pleasing, growing system any senior could build, with almost no tools and have it be more than a cherry tomato & lettuce bowl in the steps! I want to pioneer ultra small space, zone 5, vertical, modular gardening system where space and watering, young bones & lots of cash aren’t barriers. Vertical squash, melons, cubes & beans, perennial berries, root crops, greens galore and abundant flowers; water and shapes, whimsy and tranquility along with abundance. Why shouldn’t seniors have that? Intensive gardening depends on great nutrients. This product from the sea is key for producing food filled with nutrients and minerals our soil no longer has. Healthy food grows in healthy plants thriving in healthy soil. Forgive typos - I’m literally 2/3 blind... but I got vision! Buy Sea Minerals - great value... I can barely lift the bag, lol. Got 150 pots coming (apparently taking the CoVid scenic route). But when they arrive, “Katie bar the door!”

### ⭐⭐⭐⭐⭐ Essential to all gardeners.
*by A***R on November 13, 2019*

I’ve been using Sea-90 in my gardens and yard for over 10 years now, I love the results! Contrary to what some think this is more than just salt, Sea-90 has a wide array of trace minerals and microbiology that are essential to plant growth. Sadly these are missing in most topsoils today.Used as directed this will greatly enhance any soil and increase crop quality and yields. I use this together with Boogie Brew compost tea and maintaining a good level of organic material in my soil to grow and harvest chemical free food every year.I highly recommend this to any gardener especially if you’re looking for alternatives to inorganic fertilizers. I also recommend reading the companion book Sea Energy Agriculture by Dr Maynard Murray to fully understand the benefits and uses.

### ⭐⭐⭐⭐⭐ Dr Murry's creation
*by J***N on February 2, 2023*

read about Dr Murray and the Salton Sea before it is gone. This is POWERFUL Sea Minerals. Better than anything You will ever find. Buy the book and read about it first and then buy the huge bags before We lose the Salton Sea.
