Watermelons - Bradford Family Watermelon

3.14 out of 5 based on 22 customer ratings
(22 customer reviews)

In the 1850s, Nathaniel Bradford developed a unique watermelon breed that was known as the sweetest and most flavorful, right down to its dark green skin. By the early 1900s, however, watermelons had been developed with hard, thick skins and tough rinds at the sacrifice of flavor, which were ultimately more profitable because they were able to be shipped with very little breakage. And so the Bradford watermelon, fell out of cultivation and became lost to the annals of history. However, although the commercial line disappeared, the Bradford family never stopped growing the original watermelon. Recently “rediscovered,” the Bradford Family Watermelon and its unique products are being introduced to chefs, gardeners and food enthusiasts around the world.

The Bradford Family Watermelon is passing germination tests at USDA’s Seed Lab in Columbia, SC, with greater than 90% success. However, this heirloom has been grown and saved on the same farm for over 100 years, so specific environmental conditions could affect germination. This is a rare seed being reintroduced to the home gardener and we encourage you to grow and save your own stock for regional adaptation. The Bradford Watermelon is now being successfully grown all over the USA, we welcome and encourage you feedback!

***This is a late summer melon, and requires very warm soil between 80 and 85 degrees, and to be kept damp, but not wet. Feedback from our customers suggests that planting too early and/or over-watering accounts for most failures in germination. Please call anytime if you have questions about growing these delicious watermelons, we are happy to help!***

These Bradford Watermelon seeds are rare, hand-selected, hand-sorted seeds direct from the Bradford family. The majority of the seed price goes to support the Bradford family as they continue to work hard to preserve this plant and reintroduce its unique, historic products. 3 Gram Packet

Notes From Nathaniel Bradford:

Bradford Watermelons are a LATE SUMMER WATERMELON and prefer a sandy loam soil that is high in organic content and drains freely. Choose a location that best fits that soil condition in all day sun.

Cultivate the soil for the watermelon patch allowing approximately 40 square feet of growing space per plant. I prefer to lay out my patch in rows of hills spaced 8 feet apart on center from hill to hill and spacing between rows 10 feet apart on center. Each planting hill supports 2 plants.

To create your hills, dig a shallow hole about 6 to 8 inches in depth by about 18 inches across and fill the hole with well composted stable manure. Create mounds or hills over the manure using excavated soil from the hole about 8-10 inches high by 3 feet wide and flat on top.

Place seeds in the center of the mound about a half inch but no more than one inch deep. Make sure seeds are spaced out about an inch or so apart in the mound. Lightly tamp the soil over the seeds to settle out the soil and carefully water them in if desired to speed germination.

At the time the vines flop over and begin to vine across the ground, side dress the mounds with well composted stable manure at a rate of 4 rounded shovelfuls per mound along with one round shovelful of well composted poultry manure. Do not place on the mound! Scatter around the perimeter of the mound.

Tilling for weed control is good as long as there is access in the patch. Hand weed everything else. Limit walking and compacting the soil. Limit handling and disturbing the vines. Once the patch is covered with vines stay out. Resist the urge to walk through the vines and even pull weeds. Some weeds in the patch will not affect the melons at all. Compacting the soil will.

When Bradford Watermelons reach full size and a rich lustrous solid green, begin checking for ripeness. In South Carolina, it’s about 85 days from planting. There is a small tendril just opposite the stem. When it turns brown, and withered, it is a few days of being ripe. The thump test is the best way to tell after the tendril turns. It should sound solid when thumped. Immature melons have an echo sound like ping-ping. Ripe melons have a dull flat sound like punk-punk.

I have been growing our Bradford Family Watermelon for more than 30 years. I still learn more every year. Allow yourself to make some mistakes and learn as well. The joy of growing a Bradford Watermelon from seed to a 40 pound fruit, though challenging, is hard to beat and well worth the reward!

Good luck!

    I suppose you can never know why one might have a bad experience, but in Southern California, with mild weather in April, I had a heck of a type getting these seeds to sprout. I planted 9 of them on a hill and only 1 took. I planted 6 sugar baby seeds left over from last year on the hill next to it and all 6 germinated – plus one I did not even know I had dropped a couple feet away. The one that popped up has been growing strong but wish I had at least one extra plant. I will try again next year germinating in a starter tray.

    I too am an experience melon grower and I failed too get a single seed to sprout. Planted in prime soil in central Texas in the 3rd week of May. I just sent an email requesting a replacement. These melons sound wonderful and at a dollar a seed we should expect a crop.

    I have also had a hard time with my Bradford seeds in NC. Split a pack with my father-in-law neither of us have had any plants to sprout since planting 3 weeks back. Bought an extra pack for my Uncle’s garden he planted his this past week hopefully some of his will come up.

    I bought some of these to see if they lived up to the hype and like the reviewer before me I had horrible germination rates. My packet came with 12 seeds and not a single one took. After having no trouble with other seeds from this company and 1000s others I’ve planted this spring I would not recommend anyone wasting their money on these seeds.

    Zero germination. Could be my fault. Planted them in a starter tray outside in June, thought I kept them properly watered. I may try again next year.

    I grew several plants in upstate South Carolina, and had no problems. It grew well even in our clay soil (with some amendments, of course). We got a couple of melons that were deliciously sweet, although not as large as the ones the Bradfords grow. The melon had plenty of wonderful seeds that I was able to dry and save for future plantings.

    Nate- I am very pleased with the results to this point. I purchased 20 seeds and happy to report 100% germination! We reside in Alabama and decided to plant in well drained sandy soil and dressed with aged horse manure. So far so good with 5 beautiful hills a couple with softball size mellons.

    We haven’t gotten any ripe melons yet, but they are doing well. We got about 75% germination. There are 10 to twelve melons, probably more because they are hard to see under all the vines and leaves. I planted 3 hills with a couple of plants in each. I’ll come back and let you know more when we have eaten one.

    If you haven’t had a Bradford melon, you are definitely missing out. They are nothing like the round balls called watermelons in most grocery stores today. By far the best and sweetest watermelon I have ever had.
    This is my first time growing the seeds in my own garden. Germinated about 16 seeds, all but one or two made it to seedlings. I picked about 6 of the best and planted them in my very small garden. Had to trim back to the best three and from there they took off. My girls call affectionately call it “the jungle.” Right now I have 3 melons, each about 10-12″ long getting bigger by the day. There are a few other late bloomers that I hope will make it but not so sure.
    I am a very inexperienced gardener and consider myself lucky to get anything to grow or escape being dug up by the dog. I was very careful to follow the instructions with the seeds as best I could, fertilized with some old horse manure, and I feel that has made all the difference.
    Looking forward to enjoying the ripe melons later this summer.

    I planted 40 Bradford Melon seeds on the first day of June. My soil is Rosalo fine sandy loam in the upper Piedmont of North Carolina. I had a 95% germination rate. The plants are growing strong and the melons are now approximately 10″ long. I am very pleased with their progress and will post another rating after harvest.

    Seeds have been in the ground for two weeks now, with no sign of germination. I followed the planting and watering instructions , and the weather has been perfect. My garden has grown everything from tomatoes, peppers, cucumbers, melons, lettuce, beans, etc… for more than forty years. Must be a problem with the seeds.

    also 0 for 12 on germination in soil blocks. company replaced the pack so I will try again in 2017…

    I planted a bunch last spring – started some indoors in April, some in the ground 2nd week of May. I’m in WNC, so we have cooler nights.

    They did not start very vigorously. Grew slower than the crimson sweet from the previous year. But they exploded at the 2 month mark and took over the field. I got dozens of melons. I only culled a few, but those plants yeilded 40+ pound melons. They were very sweet, softer fleshed melons. They were not ripe when the tendril/small leaves dried out – i found they were best 3-7 days AFTER THE tendril was found dried up.

    Very good melon. Certainly not mushy, just not crisp.

    I wonder if anyone has tried physical seed scarification to combat this germination problem aka using some sandpaper to wear away a small portion of the seed coat so as to allow water in and the sprout out?

    • :

      Hi Hilary – this may help and it’s worth a go, however the challenges seem to be environmental because on the Bradford farm and with externalized germination testing, the seeds are 90%+ for germination, and many people have similar success, while some people have poor success.

    Couldn’t get any to germinate last year (2016) out of 24 planted in May, June, and July in eastern Mass, though all my other melons & squash came up well (kabocha, cantaloupe, 3 varieties of pumpkin). Gonna give it another try this year in a more controlled environment (start indoors, tend carefully in pots on the porch). Fingers crossed!

    I have zero seeds germinate indoors or outdoors. I have planted in sandy loam that has been raising watermelons for many, many years and no sprouts at all. I suspect they were not put up right because a few volunteer watermelons are up already next to where i planted these. i will order some more and try again.

    As per instructions I waited until June 1st (I’m in zone 7a) to plant directly outside and 6 of my 10 seeds germinated. I lost one plant to a critter, but of the remaining 5 plants they were healthy and spread all over the garden. I culled the melons down to the three earliest per plant, and they grew huge! They were by far the most delicious melons I’ve ever eaten, and I saved the seed from the melons of the three healthiest plants. I expect my saved seed will be even more vigorous for me on my farm. Can’t wait to grow (read: eat) them again this year!

    I started indoors this year and none germinated. I wrote to the company and their response was not satisfying. They basically said that i had to wait until the soil temperature was 80 degrees. Well, these are the conditions I have in my greenhouse. I think there must be a problem with their processing of the seeds.

    • :

      Hi Nina, I’m sorry you didn’t get any seeds to germinate. It sounds like you had the right soil temperature. The seeds are passing an independent germination test at above 90%, so the processing of the seeds is not the problem. However, some growers (like yourself) are experiencing low to no germination. Until only a few years ago the seeds have only been grown and saved in a very limited geographic region and perhaps that over-specialization has resulted in some unknown requirement. I know this is a frustrating thought, we hope that as more seeds are grown and saved in new areas (lots of people are having success) then the watermelon will once again be successful all over the country. If you haven’t already, please email to register your problems.

    Best watermelon I’ve ever eaten in my entire life…and I’ve been eating them for almost 30 yrs! My family enjoys growing these every year. The trick is to not plant too early and avoid soaking will kill the seed. These are desert crops that love 80 degree soil temps, so water only once at planting and wait until they come out the ground. Your patience will be rewarded with juicy goodness!

    I love this Watermelon! All of the products are amazing. As for growing the seeds, the main thing to do is FOLLOW THE DIRECTIONS! I’ve learned that the hard way! If you do everything according to what they say, you will succeed. I want to know how to grow the awarermelon Rind Pickles. LOL.

  22. 5 out of 5


    Wonderful melon! The flesh is so sweet, the rind makes great pickle but also can be eaten like cucumber. You must read and follow instructions. Do not plant too early. This melon grows for a long season. It is a very late harvest.
