I am growing a variety of watermelon called "red rocket". These are supposed to be, according to the tag, large oblong-shaped with a high yield, however, the only 2 fruit I have growing are just the size of small rockmelons and appear to have stopped growing. The oldest of these 2 is about 5 weeks now. Are my expectations of what is called large fruit and high yield too high, or do I need to do something to help them along. I have recently used Dynamic Lifter For Fruit and Citrus in the patch but am unsure if this will help. The other problem is that, although the plant is very vigorous and has plenty of flowers, it doesn't seem to fruit, even though I've used the brush trick to help pollinate. The only thing I can think of is that it doesn't get a lot of sun, but if this was the problem would that not also affect the quantity of flowers and health of the vine?
