Mold Invading My Trees – Action Required?

[ward]

Hi everyone,

 

After weeks of consistent rain and heavy humidity, I’ve noticed mold started growing around the base of my trees, mainly oil palm and cashew nut. It’s spreading on both bare clay soil and thick grass patches.

 

Any idea what kind of mold this is? Is it harmful, and should I take action?

 

Appreciate any insights!

I don't know exact ID, but it appears to be superficial on soil and fallen plant material, due to the wet conditions you have noted. I don't think it's powdery mildew and does not appear to be a plant pathogen. It will likely clear up as the dry season proceeds.  I would regard it as "nature's way" of seasonal decomp. It may be a good thing, and beneficial for soil building with your red gravel that appears to be deficient of soil organic matter content.

But keep an eye on it. If you notice the growth on the living plant parts, then re-post some new pics and we may be able to recommend an organic program fungicide like Potassium bicarbonate.  Don

Hi Don, thanks so much for the insight and advice!

 

It’s good to know this growth might actually be helping the soil, especially with building organic matter. I’ll keep an eye out for any changes, especially on the living parts, and will share an update with new pics if needed. 

 

Really appreciate the help—thanks again!
