Charleston Grey (87 days)

Heirloom Seed Package contains 2 grams or about 20 heirloom watermelon seeds

Charleston Grey watermelon was introduced in 1954 by the Southeastern Vegetable Breeding Laboratory of Charleston, South Carolina

Charleston Grey produces fruits that are large, light greenish gray, 28-35 lbs., cylindrical-shaped, 22" long by 10 in. across. 

Slice them open to find juicy, crisp, firm red flesh dripping with heavy watermelon flavor. 

Rind is thick enough to protect it from that bumpy trip to the beach house or market.  This rind also helps protect it from sunburn as the fruit is growing in the garden. 

Charleston Grey is resistant to anthracnose and fusarium wilt.

Recommended by the University of Florida Institute of Food and Agricultural Sciences.  "These seed varieties have been tested and proven resilient in the Florida backyard garden."

The Texas Cooperative Extension at Texas A&M recommends this variety for Texas!

Planting Tips:

In warmer climates, can be direct sown 1” deep once soil is above 75.  For cooler climates, start seedlings 2-3 weeks before last frost and place in final spacing of 3-4ft. on 6 ft. rows.  Loose, fertile soil in full sun will ensure a good crop.  For sweeter melons, reduce watering in the last month before harvest.

If direct seeding, don't plant seed till the soil temperature is 70 degrees or more.  Watermelons are originally from Africa and need heat to grow well.
If you do not have a long hot summer choose an organic variety that is quick to ripen. 
Because we want to get an early start we normally plant watermelon seed in four inch containers inside a greenhouse.

For Best Eating:  Water until the fruits are about the size of a tennis ball then only water if the plant totally dry.  The best tasting organic melons are concentrated in flavor because they are not over-watered.

Seeding Rate: 5,000 plants/acre, aproximately 1/2 lb.

Heirloom seeds are hardy but always take care with your garden seeds to give them the appropriate amount of moisture - not letting the vegetable seeds dry out prematurely or overwatering and possibly having them rot.
