Finally got my little tree looking healthy, but in the last two months I’ve been noticing very tiny white flecks under the leaves and in the branches. Mostly random individual flecks, but they definitely colonize in patches (like in the pics below). Leaves started turning yellow & dropping. Tried poking/prodding the flecks, nothing is moving (don't think it's a fly), looks like a scale. Really hoping it’s not the dreaded mite…
I drenched it completely with Monterey Horticultural Oil yesterday. It’s a tiny tree, so I’ll brush whatever it is off in a few days (if it’s still there). Just want to have a plan ready for the next time I notice it.
