Does Peat Moss Acidify Soil?

Some very desirable plants like rhododendrons, azaleas and blueberries demand acidic soil and many gardeners have alkaline soil which is not suitable to grow these plants. The most common solution I’ve seen is to mix peat moss with the soil to produce an acidic environment.

Peat moss is acidic so it makes sense that if you add some to your soil, the resulting soil will also be more acidic. But is this really true? How long does the acidity last? Can gardeners with alkaline soil use peat moss to grow rhododendrons, azaleas and blueberries?

Soil Factory Using Bokashi Ferment

I am seeing the term soil factory used more often, usually in discussions about Bokashi or Vermicomposting. I’ll restrict this blog to discussions about Bokashi, but most of the comments also apply to Vermicomposting.

It is claimed that Bokashi ferment, the material remaining after the fermentation process, can be used to make soil, which can then be used for house plants or in the garden. This would be quite a feat if true. It takes nature millions of years to make soil and now Bokashi enthusiasts can do it in a couple of weeks.

Can Leaves be Used to Identify Nutrient Deficiencies?

There are lots of examples of people trying to use plant leaf characteristics to identify nutrient deficiencies in the soil. This seems to make a lot of sense. If the soil is lacking a specific nutrient, it should show up in the plant and it seems to follow that by examining the physical characteristics of the leaf you should be able to identify the nutrient deficiency.

How reliable is this method of diagnosis? Can you really identify a nutrient deficiency in the soil by looking at plant leaves?

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.

Sand and Clay Don’t Make Concrete

What happens when you add sand to clay soil? Many people claim that this will make concrete and others say that it results in soil that is easier to dig. How can there be such large discrepancies about something that is so easy to test?

Why is this a problem? Gardeners with heavy clay find it difficult to dig, so they want to loosen it up. Sand is very easy to dig and it makes a lot of common sense to add it, to create a looser soil.
