Seedless watermelon growing is much the same as growing seeded varieties with a few differences. First of all, seedless watermelon seeds have a much more difficult time germinating than their counterparts. Direct sowing of seedless melons must occur when the soil is at a minimum of 70 degrees F.
Will the seeds from a seedless watermelon germinate?
Seedless watermelon should be germinated at 85oF until at least 30 to 40 percent of the seedlings have emerged. Maintain soil temperatures at 70°F to 80oF after germination. Watermelons are warm-season plants of tropical origin Seed germination and plant growth are best at warmer temperatures.
Can seedless watermelon reproduce?
Seedless watermelons are triploid. They have three sets of chromosomes. This odd number results in them being sterile and not producing seeds.
Are the seeds in seedless watermelon viable?
Seedless watermelons are always hybrids. This fact makes seed costlier. While these seedless plants are sterile, female flowers from these sterile plants can produce fruit if they are pollinated by normal pollen from a seeded watermelon or suitable pollinizer.
Can you buy seedless watermelon to plant?
Red Winner Watermelon Plants produce sweetly flavored, 15-18-pound melons with seedless, crispy red flesh on vigorous vines. Notice: because seedless varieties must have a pollinator plant growing alongside, we have included a non-harvesting pollinizer plant inside the pot.
How do you start seedless watermelon seeds?
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.
Can you plant watermelon seeds right out of the watermelon?
You can save the seeds from your watermelon to grow more plants, but you’ll have to wait until next spring to plant them. If you save the seeds from a grocery store melon, you might be surprised at the variety of fruit you produce.
Why does my seedless watermelon have seeds?
So those white seeds are really just hollow shells of seeds that haven’t matured. Yes, they are still seeds, but they are so soft and immature that they are completely edible and harmless — no spitting required.
Why does my seedless watermelon have black seeds?
In theory all of the seeds in a seedless watermelon should abort early leaving you with those white empty non-viable seeds. Occasionally seedless watermelons have a few normal looking black seeds like this. They are not hollow and certainly appear to be normal seeds.
Are seedless watermelons male or female?
In other words, a seedless watermelon is a sterile hybrid which is created by crossing male pollen for a watermelon, containing 22 chromosomes per cell, with a female watermelon flower with 44 chromosomes per cell.
How do you prepare watermelon seeds for planting?
Cut the melon, dig out the seeds. Put seeds into a large bowl and fill it with water. You will notice that the healthy(viable) seeds will sink to the bottom, while the bad seeds will float with most of the pulp. Scoop out the floating seeds and pulp and dispose of them.
Why are seedless watermelons more expensive?
Hybridizers and seed producers harvest the small percent of viable seeds to use for future plantings. This is why the seedless watermelons, seeds for planting and fruit for eating, tend to be more expensive than their seedy counterparts.
Can I plant white watermelon seeds?
Watermelon has two kinds of seeds: black and white seeds. “Black seeds are the seeds found in a regular watermelon, and they can be planted in the ground to sprout a watermelon plant, whereas white seeds are immature seeds, so they can’t be used to plant a watermelon plant,” says Tammy Lakatos Shames, RDN.
Do seedless watermelons need a pollinator?
Because seedless watermelon are not self-pollinating, pollenizers, or diploid watermelon crops, must be included in production to provide pollen, which is then transferred by bees to flowers of seedless melons.
Are seedless watermelon genetically modified?
Seedless watermelon is not a genetically modified food; it is a result of cross-breeding. The male pollen of a watermelon, containing 22 chromosomes, is crossed with the female watermelon flower, which has been chemically altered to contain 44 chromosomes.
What are the black seeds in watermelon?
The black seeds in a regular watermelon are just plain ol’ seeds. They’re mature, fertile seeds, so if you planted a few in the ground, they would indeed sprout into watermelon plants. While they’re thought to be too hard and therefore inedible, they are actually completely safe to consume.
How do farmers grow seedless watermelons?
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.
What is the difference between seedless and seeded watermelon?
The Difference Between Seeded and Seedless Watermelon
The difference between the two is that while traditional, seeded watermelon contains hard black seeds, seedless watermelon has been bred to produce very soft and pliant edible seeds.
How do you grow a seedless fruit?
Can you plant a seedless fruit? The answer is no! You can’t plant a seedless fruit, because the plants that produce them don’t occur in nature because they’re sterile. That means they can’t reproduce.
How can you tell if a watermelon seed is good?
Good seeds will sink down to the bottom of the bowl while the bad ones will float in the water. Once you have the good seeds, you can dry them and spread them along with the soil. From here, you can just leave them in the soil to dry and germinate on their own.
What month do you plant watermelon seeds?
Watermelons need about 100 days of warm weather to produce an edible melon. If the warm, late fall and winter weather of recent years continues, you may get a watermelon for Christmas. The best times to sow seeds for watermelons are early March and early August.
