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.

This version doesn’t work
I used these 2 nights in a row. I was hoping Oracoat found a solution to the problem people like me have with the regular Xylimelts: irritation of gums. As others have noted the “sensitive” version doesn’t melt and the goo that remains can be difficult to remove. I didn’t have too much trouble after the first night. However, the second day after use, it was so hard to get the remains out, I wound up with a very sore spot from digging it out. I will toss the rest. It’s too bad this effort fizzled. I hope Oracoat will find a solution For sensitive mouths. In the b meantime, I will use the original for a few nights and then stop before repeating. The idea behind the original product is fantastic. Unfortunately this attempt to make it usable for people with sensitive mouths hasn’t worked. Please try again.

An improvement over the original product, but could be better
I had used the original Xylimelts a few years back for my night time very dry mouth. They worked very well, completely dissolving overnight, but they caused sores inside my cheeks. Recently I discovered this new version which was purported to be made without the offending ingredients. They don't work quite as well, as they don't completely dissolve, but so far haven't caused any irritation. My mouth isn't completely parched as it was without any product, so it is definitely better than nothing. There is a gel-like residue in the morning that needs to be scraped off the teeth. I think Oracoat has some more R & D to do.

These work well!
These work to keep my mouth moist for hours. The only downside is the glue stays in your mouth till you can scrape it out with your finger. I thought it would dissolve but it didn’t. Very grateful to find something that moistens my mouth for so long though. They’re easy to use too. Taste slightly sweet but otherwise I didn’t notice anything.

Xylimelts Sensitive
I was sensitive to the regular Xylimelts after a few months use. Painful gums and hives inside my lips and cheeks. The sensitive version immediately corrected the problem and I’ve been using them without issue for nearly a year. The product is a lifesaver for drymouth that occurred when I was sleeping.
