If you tend to buy natural versions of many household products, you may have seen neem oil listed in the ingredients.

You may have seen neem oil soap, hand lotion, shampoo, toothpaste, etc.

As a natural insecticide, fungicide and bactericide, people have been using neem for thousands of years.

This page contains a bunch of different products, mostly derived from various types of rock.

Other than perhaps the first two, rock dust and calcium carbonate, you won’t generally use them unless you have a deficiency of specific minerals.

If you just need 20-40 pounds of something, it will probably be worth it to get it from me to save yourself time trying to find it locally.

If you need more, go local – just be prepared to search for a while, because some of these can be hard to find…

Hudson Hose End Sprayer Professional


You’ll definitely want a quality hose end sprayer if you’re going to be applying liquid organic fertilizers and inoculants.

This is the metal trigger Hudson hose end sprayer, the best hose end sprayer I’ve used.

I used to use the Gilmour hose end sprayer 362, but Gilmour has now stopped making hose end sprayers.

Luckily, I found this Hudson sprayer that as far as I can tell is exactly the same as the Gilmour – perhaps even made by the same manufacturer.

This is a professional hose end sprayer.

Molasses for plants

It sounds strange, but a can of Coke can actually be beneficial for the garden.

In fact, various forms of sugar are very useful to use in your foliar sprays.

If you’re applying any kind of microbial inoculant, such as effective microorganisms or compost tea, the right sugar will give the microbes some food to eat right when they get out there, to wake them up and get them working away on all the amazing things they do for us.

Liquid Fish Fertilizer

Along with seaweed, fish has been used as a fertilizer for centuries.

But using fish as fertilizer does beat liquid seaweed in one way – the major nutrients it contains, especially nitrogen (N) and phosphorus (P).

N and P are two important elements that are often deficient when our gardens aren’t yet up to a point of cycling nutrients optimally (which is most of the time).

Sea Minerals Fertilizer

If you’re lucky enough to live right beside the ocean, I’m envious of not only your view of the surf, but the incredible fertilizer you have at your doorstep.

Sea minerals fertilizer is definitely my favorite organic fertilizer. It has very noticeably improved the health and increased the growth and yield of many of my plants.

It’s more expensive than liquid seaweed and fish, but the application rate is lower so it ends up costing less.

Rivers and volcanoes have been adding minerals to the sea for hundreds of millions of years, which is why it’s so nutrient dense in there.

That’s what we need to emulate in our gardens.

Compost Tea Brewer Bucket

There are tens of thousands of different species of microorganisms that have a huge part to play in the health of your garden.

They kill diseases, feed and protect plants, improve the soil, and perform a long list of other jobs.

In 2006, I was running my organic gardening business and learning that my clients’ gardens were deficient in proper biology.

Mycorrhizae For Sale


Canadians can get it here

A common problem in many gardens is that plants have a difficult time getting certain nutrients out of the soil, finding enough water, and protecting themselves from soil-borne predators.

That’s why they started partnering – 100s of millions of years ago – with very special fungi called mycorrhizal fungi.

If I had to narrow it down to the single most important microorganism species for your garden, it would be a mycorrhizal fungus called Glomus intraradices.
