Q.I Lost My 20yr Old Canary Island Palm Last Fall To Suspected Crown Rot. It Went Down Hill FAST. My Neighbor Lost His Also
Now the HUGE problem. This palm was the “centerpiece” of my front yard island. I had planted a hedge of variegated arboricola around the outside perimeter years ago. The canary island palm was taken down last fall, just 2 wks after it first looked sick. This spring, all of the arboricola quickly went into decline. Now all of it is cut back to the ground. I can find no info on control/ridding this island of whatever fungus that caused the crown rot. There are other plantings in this island not effected & doing well. Sure looks horrible & we are in a retirement HOA. It was recommended that I apply a granular fungicide multiple times & wait till next spring to replant anything. Trying to find a list of plants not susceptible to the fungus causing all this heartache! PLEASE help me out here. Currently, I also have a nice hedge of arboricola across the rear of my house…which I have been drenching weekly with Daconil & daily picking up any dropped leaves & clipping off any brown spotted leaves. Trying so hard to save that hedgerow! Also have 3 other palms in the yard I’m worried about. Per advice, all three bases & roots have been drenched with copper sulfate, but I’ve been told that using copper sulfate also can have negative/toxic effect if used more than once. Right now, the Bismark & 2 Queen palms are looking fine. Feel like I am loosing all my 21 years of landscaping. Thanks for any help, brand names, plant lists, whatever you can do! Getting quite desparate here….and discouraged.

I also suggest waiting till next spring to plant anything where the canary palm was. In the meantime, incorporate lots of compost into the planting area. When you decide to plant there again, do not plant anything in the same family as a canary palm. Here is more:

I wouldn't apply any more fungicide, it could just create more problems as you say. Keep the area free of dropped leaves and continue with proper watering and fertilization.
