HOW TO GROW

Sowing: In cool climates, watermelon seeds should be started indoors, but no sooner than a month before transplanting; plant three seeds per peat pot, 1/4" deep. Provide heat to keep the soil at least 80-85 degrees F. Cut off all but the strongest seedling as soon as true leaves appear, and transplant about a week after frost; put two or three plants in each hill with a 6-8' space in all directions. Gardeners in warm climates will be able to direct sow watermelons as soon as the soil temperature reaches at least 75 degrees F, planting six seeds per hill with 6-8' of space in all directions. Thin to the strongest two or three plants as soon as the seedlings appear. Watermelons should be planted in full sun and rich, loose soil. Young seedlings may benefit from black plastic to warm up the soil.

Growing: As soon as the vines begin to develop, apply a thick layer of mulch to control weeds and protect the melons from soil contact. Keep the soil moist until the fruit begins to grow, then water only if the soil dries out completely. Watch out for insect pests, which can be a problem. Charleston Grey is resistant to anthracnose and fusarium wilt.

Harvesting: Gardeners use many different methods of testing whether their watermelons are ripe, but knowing the approximate mature size of the melon helps to determine when it is nearing ripeness. One test is to knock on the watermelon with your knuckles, listening for a dull thump rather than a hollow ring. Another method is to check the underside of the melon where it rests on the ground; the skin should be a rich yellow. Also, the curling tendril closest to the stem of the melon often indicates ripeness when it begins to turn brown. Watermelons usually keep for several weeks in a cool place.

Seed Saving: Watermelons will cross with other varieties of watermelon, so isolation may be necessary to ensure genetic purity. When the melon is ripe, the seeds will be mature. Cut open the melon and remove the seeds; wash them to remove the sticky residue. Spread them out to dry for a week, then store them in a cool place for up to four years.

At last!

I've been looking everywhere for this watermelon seed. My grandfather raised his family on his garden and this watermelon was always a favorite. I've only found this Charleston Gray on your site. I look forward to getting them. Thanks for continuing this seed and your efforts to keep our food heritage safe!

DESCRIPTION

IN-STOCK ORDERS SHIP THE NEXT BUSINESS DAY VIA THE US POST OFFICE.

Charleston Gray is a big juicy watermelon variety for your home garden! Oblong fruit average 22 to 26 long x 10 in diameter with a tough striped rind that makes this a good shipper! Mature melons weight from 25 to 35 lbs. Bright red, fiberless flesh is crisp and sweet. Matures in 85 to 100 days. Resistant to FW & AN1. Average water needs. This plant is attractive to bees, butterflies, and/or birds.
Charles Frederic Andrus, a research scientist at the USDA laboratory in Charleston, developed this melon in the late 1940s to fulfill the need for a good shipping melon that could resist disease. His Charleston Grey watermelon was introduced in 1954 by the Southeastern Vegetable Breeding Laboratory. An immediate success, it was once the most popular commercially grown melon in the United States; though other varieties have now taken this position, Charleston Gray watermelons still make the state of South Carolina proud.
