Hi--

I have 4 cantaloupe vine that by all signs are healthy and thriving. The plants were started indoors in early March, and were transplanted to containers outdoors in early April (and brought indoors during any cold spells). The vines are about 4-5 feet long, and have been in bloom for over a month, but there are no female flowers forming. How long do the vines flower before female flowers begin to appear? Any help is appreciated!
