Understory Citrus

[VUgearhead]

Just saw this video from Pete Kanaris of Green Dreams about understory citrus showing possible resilience to HLB.

Here is the YT link. Anyone seen this before? Is it just wishful thinking?

HLB is primarily a root disease that causes 50% decline before foliar symptoms occur. It could be that root health is improved in trees growing in a natural environment or because nutrient uptake is slower than typical citrus orchards which get fertigation and folair feeding.

The research does show that a steady controlled release of nutrients is better in the age of HLB.
