You shouldn't need to blanch the veggies. I've heard you lose alot of nutrients that way.
Have you found a food the pleco will eat? If so, stuff whatever it will eat in the cucumber. When I add zuchini to the tank, I usually stuff several massivore or shrimp pellets in it.
I add it to the tank at night, and pull it out in the morning. Sometimes I'll leave it in until early evening the next day (if the plecos are still actively grazing on it in the morning).
Try zuchini if you don't have any luck with cucumber, its supposed to be real nutritious for plecos.
