Golf course putting greens are covered with many types of grasses. I’ve written about my skepticism that adding Si will increase green speed in 3 posts on the blog (post 1, post 2, post 3), and I’ve done so in reference to Zoysia matrella greens which are known for the high silica content of the leaves.

A correspondent wrote to ask about the ever popular topic of Si and green speed: Pretty sure I already know the answer to this, but I had a conversation with our rep from […] fertilizer company about my frustration in not being able to increase our green speed […].

Jason Haines passed 4,000 Twitter followers in July 2017. In the turfgrass industry, that’s a lot. But wouldn’t it be nice to have more? He asked if I had any suggestions about how to get more followers as a superintendent.

Once upon a time,1 Paul Robertson asked if anyone was using a Pelzmeter to measure green speed. a long discussion followed, and the notifications on my Twitter account blew up.

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.
