Helping You Become a More Successful Gardener
CITRULLUS lanatus 'Jubilee'
Jubilee Watermelon, Watermelon
This is one huge watermelon! The large, oblong melons of ‘Jubilee’ are green striped on the exterior and have crisp, sweet, red flesh on the interior. Fruits have been known to reach up to 35 pounds (~16 kg.). ‘Jubilee’ is an ideal cultivar for the American South due to its ability to withstand high heat. The vines are also quite disease tolerant—particularly to fusarium wilt and anthracnose. This vigorous variety bears mature fruit in 95 days after planting seeds.
Watermelon is a tender annual tropical vine that needs a long, very warm growing season to produce its famous fruits. Yellow, bee-pollinated flowers appear among the attractive, deeply lobed, gray-green leaves throughout the growing season. Some flowers are male and others female. Female blooms have a bulbous ovary at the base, which will eventually become the fruit, and the males only have pollen-laden anthers.
Watermelons do not become sweeter after being harvested, so they must be picked when ripe. It is tricky to know when to harvest—especially considering the fruits take a while to mature and patience can wane. The best means is to monitor the tendril closest to the developing fruit. Once the tendril starts to turn brown, the fruit is ready. Another method is to keep an eye on stem health. When the stem is green and firm, the melon is still ripening; a soft withering green stem is an indication of ripeness, and a dry or unattached stem can mean over-ripeness. Finally, check the underside of the melon and give it a light knock. If the underside of the melon has turned from white to pale yellow and a hollow sound emanates from the fruit, it is probably ripe. When harvesting, cut the melon from its stem. Tearing the stem can lead to vine rot.
Full sun and fertile, friable loam are perfect for watermelon culture. Watermelon plants appreciate sharp drainage, so it is best to sow the seeds in low mounds of soil (called "hills"). After the threat of frost has passed, plant as many as three seeds per hill and keep the soil evenly moist but not wet (wet soil can induce seed rot). Once the small plants have emerged, keep them lightly moist and feed them regularly. Provide ample room for the plants to sprawl across the ground. The sheer weight and size of the melons precludes training the vines on trellises.
