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 25‒35 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 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 up to 20 mounds.

Days to Emerge:
5 - 10 Days

Seed Depth:
1/2”

Seed Spacing:
2-3 seeds per mound

Mound Spacing:
4'-6' apart

Thinning:
Thin to 1 plant per mouond


When to sow outside: RECOMMENDED: 1 to 2 weeks after average last frost, and when soil temperature is 70°‒90°F.

When to start inside: 2 to 4 weeks before transplanting, when weather is warm and settled. Sow into biodegradable pots that can be directly planted in the ground.

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 tendril on the stem near the point of attachment of the melon is brown and dry. All of these indicators may not necessarily occur at the same time.
