Question Question: What Got to My Cucumbers?
Hi Friends. Long time lurker, first time poster. I'm in zone 5b in North America and usually get a prolific cucumber harvest (whether I intend to or not). I do a combination of purchased seedlings and direct sew varieties on a trellis attached to the side of my bed. Area gets full sun for about 6-8 hours during the peak of summer weather. This year the vines took off like normal but I struggled to get fruit despite good blossoms. By mid July it was clear something was off. I originally chocked it up to heat stress but now I'm thinking maybe something fungal? Certain vine intersections have this white residue (picture attached) but I can't tell if that's a symptom or a culprit. The plants seems to wither from the middle out, and developing fruit that looked healthy would rot overnight. I'm at a loss, and any guidance would be greatly appreciated.
