Notes From Nathaniel Bradford:
Bradford Watermelons 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!
