Thin liquid weeping from tip?
Tonight, I had this Italian Honey cutting with thin liquid running out of the top cut - so much liquid that it was running down the entire 4" of the exposed cutting. A few months back, I had similar liquid running out of a Latarrula cutting, it was also running out near the terminal end, but that one had a terminal bud, and the weeping was coming from base of the bud, where the bud meets the cambium. That Latarulla cutting never did make it, even as strong and thick as it looked, even with all the amazing roots, it just shrivelled up and went limp, and the terminal buds never broke.
Even stranger, in the two minutes it took me to finish what I was doing and walk to get my Blackberry to take a picture of the liquid cascading down the cutting, the liquid evaporated, so I couldn't show you that there was a puddle the entire width of the cutting flowing from the clearly-soaked cut site on top. There was no residue left behind after evaporation. This wasn't sap.
This cutting has been subjected to no different amount of watering or other environmental variables than any other cutting I'm rooting right now (we talking ~50-60 cuttings or more in bins).
So, what exactly is it?
As you see below, the tip is still soaking wet in this picture - I didn't cut it recently, it came alread-cut like this several weeks ago. This cutting isn't super important to me because I have 6 backups of the same variety rooting just fine, with no liquid flow out of the top. I just want to know what this is for future reference, since I've never encountered it with other fruits and veggies I've propagated.
NOTE: A leaf or two is slightly mottled ad one is snapped off because the cutting sprouted in the bag prior to rooting. I never take my cuttings out until they're showing reasonable numbers of actual roots.
