I received this question about leaching salts from the rootzone: “I remember talking to you once before regarding flushing excess salts from the root zone and the application of gypsum or other calcium products before the flush and you telling me it was not necessary.

Not everyone understands how the MLSN guidelines work. I saw a photo shared by Andrew McDaniel followed by a number of replies from STSAsia exhibiting confusion on the latter’s part about the use of the MLSN guidelines.
