Worm castings and tea for white fly

I added more worm tea to the Mandarin, worm castings under both the Mandarin and Valencia, and rubbed some white fly off each.  There was much less today, but I'd just done a lot of physical removal 2 days ago.

White fly on the mandarin

This afternoon I notices a bunch of white fly covering the undersides of leaves on the mandarin tree, which is still very small. Some growth new this autumn was curling and unhealthy. There were small patches of white fly also on the nearby valencia. Daughter and I spent most of an hour rubbing off white fly by hand and rinsing the leaves. When we finished, I poured worm tea over the entire tree and into the soil. Hopefully this helps turn the tide.
