Triangle palm

Question

I have two triangles palms approx. 20 ft high . One just fell over. Totally rotten on bottom. How do I save other one? Can I plant another?

Answer 1

It sounds like your soil has gotten a bad infection. I would recommend using wettable sulfur to kill off the infection. When you add this, you will also want to add dolomitic lime to keep the pH stable while the sulfur kills off the infection.

I would wait about a month to replant to be sure the infection in gone. The other tree may, or may not already have the infection. It is possible that it can recover without showing symptoms, but it is more likely to share the same fate.

Treat the area as I described, and you will be able to plant again within a month or so.
