Dig holes in the ground for the transplants. Place one-seeded watermelon in the first row and transplant seedless watermelons into the next two holes. Continue to stagger your plantings, with one-seeded variety to every two seedless. Water the transplants in and wait, about 85-100 days, for the fruit to mature.
How do you grow seedless watermelons if they have no seeds?
Seedless watermelons are triploid. They have three sets of chromosomes. This odd number results in them being sterile and not producing seeds. The way they become triploid is by mating a diploid male with a tetraploid female.
Will seeds from a seedless watermelon grow?
Seedless watermelon fruit will have white seed traces, but only occasionally will it have a mature, brown, hard seed. Since the pollen of these plants is not viable, a diploid, seeded watermelon needs to be planted along with the seedless variety.
Are seedless watermelon genetically modified?
Seedless watermelon is not a genetically modified food; it is a result of cross-breeding. The result is a watermelon with 33 chromosomes, and the tiny white seed husks don’t mature into fertile seeds and therefore is sterile.
Where do seeds for seedless watermelon come from?
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.
Can you grow watermelon from white seeds?
White seeds are really just immature black seeds. The seeds are infertile, so they won’t sprout into a watermelon plant if you planted them.
What is the best month to plant watermelon?

Can you still buy seeded watermelon?
While the seedless and mini varieties have taken over in popularity and demand, there certainly are still many folks who grow and sell the seeded watermelons, oblong in shape, chock full of black seeds.
What is the disadvantage of seedless fruit to humans?
The major disadvantage to breeding seedless fruits is the reduction in the diversity of cultivated fruits, leading to a higher susceptibility to pests or diseases, which could wipe out all of these genetically identical clones.
How can you tell if a watermelon is male or female?
The male flowers appear first on the plant and the female flowers follow a week or two later. It’s easy to tell the difference between the two. A male flower will connect directly to the vine while a female flower will have a bulb behind the flower. The bulb behind the flower looks like a miniature watermelon.
How do you plant watermelon?
You can sow watermelons directly into the ground when the soil temperature is above 65°F. Plant seeds 1/2 to 1 inch deep, placing two or three seeds in groups 18 to 24 inches apart. Once watermelon seedlings are established, remove two and leave the best watermelon plant in each group.
Why does my seedless watermelon have seeds?
Seedless watermelons are known in the trade as triploid watermelons; they contain three sets of chromosomes. Plant breeders obtain seeds for these melons as the result of crossing a melon that has double chromosomes with a regular watermelon. This is done by hand pollination.
Can you plant watermelon seeds straight from the fruit?
If you’re up for a challenge, or just curious, and decide to use seeds from a store-bought watermelon (or are using seeds from an open pollinated heirloom watermelon), you’ll need to dry the seeds before you plant them. Once they’re dry, you can plant them!.
Can you grow watermelon from store-bought watermelon?
How to Plant Melons from the Grocery Store. In order to grow seeds from a store-bought melon, it’s essential the seeds are harvested, cleaned, and stored properly. In addition, many grocery store melons were picked before they were ripe, which can result in immature seeds that won’t germinate.
What do watermelon seeds look like?
The seeds are small and black or slightly mottled black/brown in color. Although usually discarded, the seeds are edible and delicious when roasted. They are also highly nutritious and high in fat as well. One cup of watermelon seeds has over 600 calories.
Do you soak watermelon seeds before planting?
Many types of plant seeds benefit from pre-planting soaking to soften the outer seed coating and hasten germination. However, watermelons are an exception to the rule. Soaking the seeds before planting increases the risks of various fungal diseases, such as anthracnose caused by the Colletotrichum lagenarium fungus.
How long will it take for watermelon seeds to sprout?
Seeds will germinate in 4–12 days.
What is the fastest way to germinate melon seeds?
Melons can be started from seed indoors a month before the last frost date. Plant three seeds per cell or per pot in sterile-seed starting mix, a quarter-inch deep, and place the containers over a seedling heat mat set to 85°F. The seeds should germinate in three to four days at that temperature.
