Areca Palm W/Orchids Has Fungus
 

I need HELP, PLEASE. I have an Areca Palm Clump. It is about 15 feet at highest point, there are about 10-12 individual trunks. It has developed a fungus that can be controlled(not cured) by Copper Fungicide or Neem Oil, Sprayed on fronds. My problem, I have several large (Vandas, Dendrobiums) orchids attached to trunks. Over spray will obviously cover the orchids. I am also worried about the ECO damage to the ground and critters living there. Any of you have experience is this or a similar situation. Any and All suggestions are greatfully accepted and appreciated. THANK YOU

You may want to consider liberal use of plant probiotics:

What do Plant Probiotics Do?

Hi Ray, I use Probiotics I got from you for my orchids. How would that work for the Areca's

Same way, but palms don't have the thick, waxy cuticles on their leaves that many orchids do, so foliar uptake is also effective.

Thanks Ray, Of I wanted to pour on roots, what dosage would I try. Thanks Again

The manufacturer recommends 2-3 ounces/gallon, every 14-21 days. That will get a good population going. I would recommend that you spray and drench.

Once you’ve done that a couple of times, I drop the rate to 1-2 oz, once a month

Do not expect to see a sudden turnaround. Such treatments take time and do nothing to repair damaged tissues. You’re much more likely to realize issues aren’t progressing a few weeks in.

If you have used any disinfectants or bactericides, wait 3-4 weeks before applying live microbes.
