I've moved FW umpteen times trying to beat the spring desiccation and brown spot. No luck yet but still trying. Today I noticed a strange substance on the leaf edges. It appears to be like a sap, almost like a slug trail but I know it isn't. It is mostly on the very edge of the leaf and it appears to come from within the plant. Anyone have any knowledge of this and wonder if there is some association to the desiccation?

The picture is not great but you can see the white, which is actually clear.

I would have guessed a slug trail, but I believe you that it isn't, especially since you're looking at it with your own eyes. I do wonder what the heck it is, though. I'm not very helpful, I know. Sorry.

all i see is the typical spring dessication .. and one bug hole ..

there is some bug.. that seems to eat one layer of leaf .. and maybe it is that bug.. but i dont know what does that ... pillbugs MAYBE ...

I know the pics are poor but the white on the edge is a liquid and can be wiped off. I do have pillbugs but I didn't think they attributed to the dessication. Another pic, maybe shows the sap? better. Thx Ken

There is a Black Cherry tree with a slight overhang but I don't think it drips any sap. On another note it is a PIA when seeds fall and grow, thousands of them!

I know dessication doesn't wipe off, I've been dealing with it for years on FW. I guess this was just a wild goose chase.

What does it feel like? Water or slimy?

I did wipe it off, didn't notice "sticky" but it was a very small amount. APHIDS, I'd say a strong possibility. Don't know why that didn't cross my mind. I guess I was only thinking about the future dessication and brown spots. Tunnel vision...Thanks all, going to keep an extra close watch on it this year.
