On Friday we had a really good zoom call with Mark Robinson, one of the top palm guys in the world. Also on the call was Spencer Bemus of Bemus Landscape in San Diego, Duane Faloni from Sperber in San Jose, Dustin Kelly in Sacramento. We talked a lot about diagnosing and testing procedures for Fusarium. Big take away for Phoenix is you should be fertilizing your Canary Island dates 4X per year. Pretty sure nobody is doing that.

I was looking at some trees in Mare Island Ca. Look at the trunk on this eucalyptus that’s about a 4 foot 2 x 6 in front of it for reference.

Did you know this little 40 page book tells you almost everything you need to know about fertilization. If you don’t have a years old organic nutrient cycling program for your not native trees, they probably need fertilizing. But if you’re doing it wrong, you could be doing more hard than good. One message throughout the book is recommending testing before fertilizing and almost everyone skips this crucial step to effectively fertilizing.
