|Ph and nutrients all test fine in rose garden soil. But, report shows sodium content is excessive @ 177 ppm. Should I treat with gypsum?|
Gypsum will help displace sodium from the soil particles and then with a drenching with water the sodium can be moved out of the root zone. Check the irrigation water by having it tested to see if it is contributing to the sodium problem. If so you may need to come up with another source of irrigation water.
Thanks for the question. Please stop in again soon!
