A repeated question re: black spot on red tip photinia

[sandih]

I have been organic for over 15 years, inside my home and in my garden. We moved into Lake Highlands about 1.5 yrs ago and there's a row of photinias along the fence. I hate them, my husband does not. One of them has developed the dreaded and often fatal black spot/fungal disease that spreads quickly to the others.

I need to know if there's an organic treatment that works very quickly. I have read about the corn meal sprays and the other things to mix in around the base.

Tell me what you personally used that worked. I know what Howard says, so tell me what YOU have used as well.

Thanks!

Just use the Sick Tree Treatment

I used the sick tree treatment on my hollies and it worked very well! They were looking so sick. They had black spot and the leaves were falling off like mad. I also used corn meal. They look really healthy now. It took about 2 months to see all the good results.
