Mycorrhizal Fungi (mycorrhiza) Myth

There is no doubt that mycorrhizae fungi play an important role in plant growth. They help aggregate the soil which in turn provides plant roots with better access to water and oxygen. Their symbiotic relationship with plants helps them access water and nutrients. It is only natural that companies want to sell these fungi to you. Don’t fall for it.

What is Salt – Salts May Not be What You Think

Some people won’t use synthetic fertilizer because it contains “salts”. For years I was told not to use mushroom compost because it contains “too many salts”. Salt is also recommended to kill weeds and just today I saw a post which suggested pink Himalayan salt makes plants grow better. You can buy commercial sea salt to fertilize your plants. This doesn’t make sense. Salt is a weed killer and it’s a good fertilizer?

As a gardener it is crucial that you understand which salt is being discussed so you donโ€™t use the wrong one and harm your plants. This blog will help you through the maze of salt crystals.

Today I will dig deep into this myth and uncover some surprising facts. Then I will review the latest research on the subject.

In this post I will have a closer look at something called seed dormancy. What causes it and how do you overcome it so the seed germinates.
