Garden Myths - Learn the truth about gardening

Walnuts, Juglone and Allelopathy

The common statement “nothing grows under walnut trees” is not true. “Walnuts produce juglone”, is not entirely true either. “You need to compost walnut wood chips before using them in the garden”, is false. “The allelopathic properties of walnuts are well understood” – definitely not true.

This is a popular subject that is routinely discussed and written about, but the truth around walnut trees is anything but clear.

Salts Don’t Kill Plants or Microbes

The idea that salts kill plants and microbes seems very prevalent, especially among organic growers. The topic is poorly understood and leads to a number of statements that are either false or mostly false.

“Fertilizer kills plants because it is a salt”

“Farmer fields are devoid of microbes because of the salt in fertilizer”

“The NPK in manufactured fertilizer is made soluble by chemically attaching the NPK to salts”

“They [fertilizers] also make it easier for the chemicals to run off into waterways”

“Organic sources contain fewer salts”

“Organic sources are slow release”

“Fertilizers are designed to be highly soluble”

It’s time for a chemistry lesson to better understand salts, ions and the difference between synthetic and organic fertilizer.

Bokashi vs Composting

Bokashi is a fermentation method used for processing kitchen scraps in the home with very little mess and no foul odors. Some claim that bokashi is a method of composting, but that is incorrect, as discussed in Bokashi Composting Myths.

What exactly is bokashi? We call it a fermentation process but what does that mean? How does fermentation compare to composting on a molecular level? Does one method have advantages over the other?

Garden Myths Book Is Released

I started collecting and writing about garden myths about 10 years ago and have been thinking about putting them into a book format for several years. Writing a book is a big job so I decided to start this blog instead. If I lost interest and only wrote about a few myths, at least they would be published in some form. More than 3 years later I am still posting myths and this blog has become extremely popular, so I finally decided to take the plunge and write a book about them. I am pleased to announce that it was released this week.

Sunlight Calculator – Another Product You Don’t Need

Someone on a social site asked if anyone knew of a light meter that would measure the amount of light in their garden. I burst out in laughter thinking this was a great joke. Then someone posted a link to just such a product; the Sunlight Calculator. I cried. Are people really dumb enough to buy such a product?
