Coverage & Planting Details
| Coverage | This packet sows up to 14 mounds. |
|---|---|
| Row Spacing | 4'–6' apart |
| Seed Depth | ½" |
| Seed Spacing | 2–3 seeds per mound |
| Thinning | When 3 leaves, thin to 1 plant per mound |
| Germination | 5–10 days |
| Start Indoors | Not recommended except in very short growing seasons, 2 to 4 weeks before transplanting. Roots are sensitive to disturbance; sow in biodegradable pots that can be planted directly into the ground. Transplant when soil temperature is at least 60°F. |
| Direct Sow | RECOMMENDED. 1 to 2 weeks after your average last frost date, and when soil temperature is 70°–90°F. |
| Growing & 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. |

- Raejean P.AZ, United StatesVerified BuyerRated 5 out of 5 stars7/11/26So happy I had to write another review with pics
This is our new favorite watermelon variety! This actually tastes like an old-fashioned watermelon from my childhood before everything went seedless! So sweet! Perfect! This watermelon weighed 9 lbs. 15 oz. and the vines are so prolific. We have watermelon coming out our ears, we are in heaven and so are our neighbors!

Watermelon vines normally only have a couple, this variety has many many melons per vine. 7 pounds 14 ounces! They do have a lot of seeds, I think I’ll save some to plant next year to see what happens.

- Elvy N.Rated 1 out of 5 stars6/22/26Very bad germination rate
I sowed 5 little mounds and only 1 plant germinated. Did a germination test on the rest of the seeds and sure enough the germination was very poor. Botanical interest has been great for seeds and I don't think this reflects on their general quality, but this one was a disappointment.

- Daniel M.Verified BuyerRated 1 out of 5 stars6/22/26Poor germination
I attempted outdoor and indoor germination with this variety this year. I tried multiple attempts for both and got no germination. I would have gotten more watermelon buying a melon from the grocery store. Pretty disappointed in this one.
