I have 9 plants in my backyard in 3 hills in a pretty tight space. They are very healthy with dozens of female flowers and tons of males. The problem is, every time I pollinate a female it dies. Some are growing a bit for a week, then the tiny watermelon falls off.
I keep well watered, and we are going trough a heat spell (90 degree days). I have been using liquid seaweed. Like I said the plants are all very healthy, I just can't get a watermelon to grow.
Last year I had three plants and three small but delicious watermelon.
It's early enough in the season, but I'm looking to get a few going. Maybe I should cut some vines? Some plants may have a few females. It's one giant mess I can't tell what's what.
Help please!
