Watermelon Charleston Gray HEIRLOOM Seeds

Watermelon Charleston Gray HEIRLOOM Seeds

Citrullus lanatus

Item #0284

85-100 days. It's worth the wait for these large, juicy fruits that average 22”-26” long and 25 to 35 pounds. You’ll have lots of thick slices for those late summer barbecues and picnics! This open pollinated melon, developed by renowned watermelon breeder Charles Andrus of the USDA lab in Charleston, SC, was the first to be resistant to both fusarium wilt and anthracnose disease. Greenish-gray rind protects melon from sunburn. It is still affectionately called “that gray melon from Charleston”.

This packet sows 12 mounds.

Days to Emerge:
5 - 10 Days

Seed Depth:
1/2”

Seed Spacing:
3 seeds per mound

Mound Spacing:
6' apart

Thinning:
When 4" vines, thin to 2 per mound


When to sow outside: Recommended only for USDA zone 8 or warmer: 1 to 2 weeks after average last frost, and when temperatures are warm.

When to start inside: Recommended for USDA zones 7 or colder: 4 to 6 weeks before average last frost.

Harvesting: It can be tricky to know exactly when a watermelon is ripe and ready to pick. First, know the number of “days to harvest” and begin checking fruits as harvest date draws closer. Signs to look for are:
(1) the bottom of the melon (where it lies on the soil) turns from light green to a yellowish color; (2) the surface color of the fruit turns dull; (3) the skin becomes resistant to penetration by the thumbnail and is rough to the touch; and (4) light green, curly tendrils on the stem near the point of attachment of the melon start to yellow and turn brown. All of these indicators may not necessarily occur at the same time.
