I am growing watermelons for the first time and things have been going great. I have healthy vines with nice green leaves and plenty of male and female flowers. Many of the female flower bulbs (the little fruit under the female flower) are now the size of a big marble. Early in the female flower production stage, I saw female bulbs the size of peas. I have searched the internet everywhere but I cannot find how big an unpollinated female flower will grow before it falls off the vine.
If the little watermelons are the size of big marbles, does this mean they are filling with water because they were pollinated?
The plants I have will produce the oblong, light and dark striped rind watermelons. I leave for work too early in the morning to see whether the female flowers are opening during the day and by the time I get home the flowers are already closed for the day.
Any help is much appreciated.
