Happy sap?
Hi guys, lately I've been noticing that a few of my orchids are extruding some clear sap from the undersides of the leaves. I know this can be an indication of pests but look as i may, i can't seem to find any mites or scale. No webs, no red streaks with wiping, no little mealy bugs or scale that i can see... On my phals is usually on the edges of the leaves and on the den its mainly at the underside of the leaf where the leaf meets the cane. I have been putting them outside these couple of days as we've had some nice weather. I doing knife if that would affect anything... Should i have any cause for alarm?
