We’re adding a new link regarding the use of Epsom Salts in the garden.
There is a Plant Talk #1601 on the CSU Extension site that refers to the use of this and you need to read and understand what type soil your garden really contains before deciding to use Epsom Salts. Soils in the mountains, front range and eastern plains can be very different in the way they’re composed, which would determine whether or not the Epsom Salts are beneficial for you or not.
The link outside the Extension site is : https://www.backyardboss.net/epsom-salt-for-plants/
Soil tests can be done for a fee by the CSU experts and you can contact Master Gardeners at the Pueblo Extension office for details.
