I have them, if you are interested. Let me know.

Not too much rain. This plant has had yellowing of the leaves since it was a seedling. I have gotten a few messages from people that the Golden Midget just has yellowish leaves. I can propose that maybe the fruit turning yellow/falling off is because of lack of pollination? I have a blacktail mountain watermelon growing right next to it that has no problems.

Blacktails and Sugarbabies have a bright yellow bottom from the start so don't go by that clue. The yellow bottom clue works well for larger white bottomed melons. Besides the brown tendril and other good clues posted above another one I find useful (esp for small melons easy to turn over) is to look for tiny black specks on the bottom that don't rub off. These are mildew specks and indicate that the melon has sat on the ground for a long time, long enough to be ripe. These black dots show up after the tendril has browned. The black specks are very small (smaller than this period . ) and are found grouped up in a patch of dots. If you ever buy a melon at the store it's the one clue to look for (within the yellow bottom) since no tendrils are attached.
