Mag, Armenian cuke is actually a type of melon (Cucumis melo var flexuosus), not a true cucumber (Cucumis sativus). The current crops' flavors wouldn't be affected by cross pollination. I avoid cross pollination by using tightly fitting floating row covers. For a day or two one variety is exposed to bee activity while nearby relatives are covered with the fabric. After that another variety is exposed and the other potential parents are covered by fabric. In the cool spring around here I do hand pollinate to get some early fruiting: bundle some male stamens together and swish them inside the corollas against the female styles. Watch out for resting bumble bees early in the morning!

Yes, different varieties of watermelons can be grown close together. Noooo....this practice would not cause the fruit to develop abnormally? That just doesn't happen. Are you thinking of cross pollination? Watermelons won't cross with other melons, only watermelons. Same for cantaloupe. If you grow more than one type of melon from the same family in close proximity and you grow those seeds out next year you'd likely get some strange melons NEXT YEAR.

Are you saving seed? If not don't worry about cross pollination. Cross pollination only effects the seed and only for the next generation. If you want to save seed for next year's crop you will have to bag (tape) the blossoms and hand pollinate. Zeuspaul

Chances are better than good, Breezy. With rare exception (such as with corn), new traits do not appear until the next generation, because the genetic changes are in the seed. So if you plant both Collective Farm Woman (which, btw, is a very good melon) and Golden Jenny they will both grow fruit the first year that is true to type (presuming the seed is pure and there are no mutations). However, if you save seed from both, and have not taken steps to isolate them, then there's a good chance that they will cross, and next year you'll get something totally different.
