Phytophthora Root Rot
From: McQueen Landscaping, Berkley, CA
My company has been maintaining a high-end estate with many mature rhododendrons, most of which have been in the ground 10 to 15 years. The rhododendrons began to exhibit die-back and leaf wilting, and several plants died. Shortly thereafter, Phytophthora fungus was diagnosed in the landscaping beds. I immediately started using Growth Products' Companion Biological Fungicide, Essential Plus, and "TKO" Phosphite 0-29-26. One month after the first application the rhodies showed promising new growth. By that summer, the plants once again looked vigorous and healthy, and the following spring the rhododendrons had gorgeous blooms. I have not lost any plants since we started applying Growth Products. And now that the plants are healthy, I feed them with Growth Products' 14-7-14 All Purpose fertilizer to keep the plants in tip-top shape.
