Q.Bucket mixup
I am growing sugar baby watermelon and Spacemastet Cucumbers and cantaloupe on my balcony in five gallon buckets. I know it is incredibly stupid but I am beginning to suspect that I got either my seeds or buckets mixed up. And to add to the confusion, they are all growing on trellises and are more than the two or three feet that the cukes are supposed to be. There are lots of yellow flowers but so far no sign of fruit. It is the second floor and even though I have lots of spiders, I apparently have no bees. I guess that I will have to self-pollinate. I have tried to match the leaves with pictures on the internet but do not find many good leaf pictures. Two of them are very similar in size and look but one comes to a definite point on bottom. The third is more split (fancier). I am not doing a very good job at the descriptions.

Thanks to the internet I found the answer to my question. I entered watermelon leaves as well as cucumber leaves and cantaloupe leaves and was able to sort things out. I even found two very little watermelons growing on what I had thought was my cantaloupe plants. A bad storm last week blew off all the watermelon and cantaloupe flowers so I hope I will get more. It also knocked off one of my only two peppers and removed its flowers but I can see there is new growth coming at the bottom of the plant. As far as the cucumbers, there are lots of very small cucumbers and lots of flowers. But the vines are 5 to 6 feet long and the Spacemaster info says it should be between 2 to 3 feet long. So i'm wondering if I should cut them back? Thanks for any help that I may get.
