“A neighbour gave me some Wollastonite to try on my tomatoes as a calcium supplement to help with foliage issues. Worked like a charm. Hoping to buy it locally next season”

“We have been successfully growing walnuts, oaks, and fruit trees in a very cold climate, -42C at times, where wollastonite/CW Grow is one of our main tools in helping trees adapt to colder climates.”

Jeremie, Permex – Val David, QC

“Tried Wollastonite last year as a solution to grubs and digging. It worked so well I used it once again this year. Very pleased with the results. I’m told it’s great for gardens and trees and I plan to use it next year on all.”

Robert – Russell, ON
