Overview

Congo watermelon is a classic heirloom known for its large, oblong fruit and sweet, juicy red flesh. Popular for generations, this variety delivers dependable yields and that true, old-fashioned watermelon flavor perfect for summer gatherings.

Conditions

For soil, use a fertile, well-draining potting mix that’s high in organic matter. For the best quality melons, provide full sun (6+ hours of direct sunlight) and consistent soil moisture during the growing season. Watermelons also need ample vining space, so plan accordingly.

Planting

Watermelons are most commonly planted directly outdoors in the garden once soil is above 70°F.  Use our grow calendar tool to find specific planting dates for your region! Seeds germinate in 7-14 days. 

Plant seeds outdoors in groups of 2–3 seeds (each seed ~3” apart), 1" deep, 18-36" apart in rows that are 5 to  6 feet apart. Plant seeds in hills or hilled rows to keep soil temperature high and provide good drainage. Thin to 1 plant per group as seedlings develop.

Pests and Disease

"Sudden wilt" is a complex disease and cold weather stress syndrome in late summer when plants have a heavy set of ripening watermelons, can cause plants to wilt almost overnight. Keep plants healthy with good fertility and irrigation to avoid sudden wilt.

Protect against cucumber beetles with floating row covers applied at germination.

Harvest

There are 3 ways to tell when a watermelon is ripe: 1) the tendril nearest the point on the vine where fruit stem attaches is browning/dead; 2) the spot where the fruit rests on the ground is yellow; and 3) the classic mystery — you hear "punk," as opposed to "pink" or "pank," when you flick the melon with your fingers. Stems should be cut with a sharp knife close to the fruit.

Such a convenient little tool
Color: Red/Battery
Once I figured out how to use it, I wondered what took me so long to purchase it. Very easy to get the hang of using. Not too fast, not too heavy, not too noisy, just perfect can opener without all the hardworking and spilling contents all over the place.

Don’t buy it
Color: Red/Battery
Stoped working after 6 months. I wish I had purchased the same one I had, Kitchen Mama, but the price was better for Circle Joy. Silly me I won’t be fooled again. I have arthritis and can’t use manual openers. This is going in the trash today. Btw- I only use it 1 or 2 times a week.
