Dealing with cholorotic Nozomi Rose - Part 4 (Conclusion)

by Richard Chew




This is an update since the last posting a month ago http://rosegrowing.blogspot.com/2008/12/dealing-with-cholorotic-nozomi-rose_22.html





The result is encouraging. New flower bulbs emerged. It successfully endured the rainy period in December.






Another bulb....




I have learned that most of the times symptoms of nutrient deficiencies may not necessary be corrected by supplementing the deficient nutrients. The likely possible cause is due to high soil pH that reduces the nutrient absorbtion rate, thus cause the plant to exhibit the symptoms. Correcting the soil pH will very likely improve the result.



The above picture was taken last November before the leaves withered off. I am led to believe that the continous rain during November and December had a dramatic impact on the soil pH, which in this case caused the chlorosis. Adding organic materials on top of the soil not just helped correcting the soil pH but also help reduce irritation to the soil organism like earth worms from the pelting rain at the surface.

In conclusion, I feel it is imperative that soil pH is checked before treating nutrient deficient symptoms. Another point I wish to highlight before I close, is that a month ago, I received a comment from a reader saying that this rose isn't a Nozomi rose. After checking from some other sources, I must admit that it is true that what I have is not a Nozomi rose.

Thank you for following my story in dealing with chlorosis. Hope this is good resource for you in dealing with plant diseases.

Wish you Happy Chinese New Year.
