Because they can't be grown from seed, therefore they have to be hand-propagated from cuttings. These cuttings have to be looked after in heated greenhouses through the winter.

Poor seed germination contributes some to the cost, but I have seen watermelons with and without seed for the same low price many, many times. I think part of the high price you see might be simply because people will pay for the convenience of not having seeds--supply and demand drive the price. I love watermelon and prefer the kind with seeds. Maybe it's my imagination, but it seems sweeter.

Seedless watermelons DO come from seeds. Here's how according to the Texas Agricultural Extension Service:


"Seed Production: The obvious question asked about growing seedless watermelons is: "How does one obtain seed of a seedless watermelon?" Obviously, you cannot save seed from a seedless watermelon. So, where do the seeds come from? Simply stated, the number of chromosomes (the threadlike bodies within cells that contain the inheritance units called genes) in a normal watermelon plant is doubled by the use of the chemical colchicine.

"Doubling a normal (diploid) watermelon results in a tetraploid plant (one having four sets of chromosomes). When the tetraploid plant is bred back, or pollinated, by a diploid or normal plant, the resulting seed produces a triploid plant that is basically a "mule" of the plant kingdom, and it produces seedless watermelons. Seed of seedless varieties are available from most major seed companies."

They are grown this way from special seeds and are called a "Seedless" watermelon. I had one last weekend and it was wonderful. I hate dealing with those big black watermelon seeds that the regular ones have.e
