A whole watermelon weighs 15-30 pounds and consists of roughly 60-65% red flesh, 30-35% rind (the white-green outer portion), and 1-3% seeds. When most households eat watermelon, the flesh gets eaten and the rind goes straight to trash — pounds of material per melon, multiplied across millions of melons consumed every summer in the US alone.

That’s a substantial waste stream that has three legitimate uses worth knowing about: the Southern American pickled-watermelon-rind tradition that preserves the rind as a sweet-sour condiment, composting (which works fine but has a few quirks worth knowing), and feeding the rind to chickens, pigs, or other livestock. None of these uses are well-known to most households, but all are practical and have long histories.
This is a practical look at all three options, with methods for each.
The Pickled Watermelon Rind Tradition
Pickled watermelon rind is a quietly persistent Southern American tradition with roots that go back to the colonial era and likely earlier — many cultures with melon traditions developed pickling methods for the rind. The product is a sweet-sour, slightly translucent pickle that pairs well with ham, barbecue, charcuterie, salads, and as a side condiment. The texture is crisp-tender, distinctive from cucumber pickles, and the color ranges from pale green to light pink depending on the recipe.
The basic method takes a day or two but the actual hands-on time is modest.
Step 1: Prepare the rind.
Peel off the dark green outer skin entirely (a vegetable peeler works). What remains is the white-green inner rind. Cut it into 1-2 inch cubes or strips. The flesh-side edge of the rind sometimes carries a thin pink layer of remaining watermelon flesh; trim or leave depending on preference.
For a typical 20-pound watermelon, the trimmed rind yields about 3-5 pounds of cubes — enough for 3-6 pint jars of pickled rind.
Step 2: Salt soak.
Cover the rind cubes with a brine of 1/4 cup salt to 4 cups water and let sit overnight (8-12 hours) in the refrigerator. The salt soak draws out water and firms up the texture, which is critical for getting the right snap in the finished pickle.
Step 3: Drain, rinse, and parboil.
Drain the salt brine, rinse the cubes thoroughly, and parboil in plain water for 5-10 minutes until just tender (a fork should pierce easily but not crush). Drain again.
Step 4: Make the pickling syrup.
A traditional Southern recipe uses:
– 2 cups water
– 4 cups vinegar (apple cider or white)
– 4 cups sugar
– 2-4 tablespoons pickling spice (cinnamon, cloves, allspice, mustard seed)
– 2-4 lemon slices
Bring to a boil. Add the rind cubes. Simmer 10-15 minutes until the rind becomes slightly translucent.
Step 5: Jar and process.
For shelf-stable storage, pack the rind into sterilized canning jars, cover with hot syrup leaving 1/2 inch headspace, seal with lids, and water-bath process for 10-15 minutes. Properly sealed jars last 12-18 months in the pantry.
For refrigerator-only storage, skip the water-bath; the jars last 2-4 weeks in the fridge.
Cost: $1-3 per jar for ingredients plus reusable jar costs (one-time investment).
Yield from one watermelon: 3-6 pint jars depending on rind volume.
This tradition has held in Southern home kitchens through generations because it’s tasty, frugal, and turns waste into something genuinely usable. Older Southern cookbooks (Joy of Cooking, classic Southern Living editions, regional church cookbooks) usually have at least one watermelon rind pickle recipe. Modern food writers like J. Kenji López-Alt and Stella Parks have written practical updates of the technique for contemporary cooks.
Composting Watermelon Rinds
For households that don’t pickle, composting is the next-best option. Watermelon rinds compost cleanly with a few specifics worth knowing.
Composting characteristics:
– High moisture content (90%+ water)
– High nitrogen content
– Soft enough to decompose quickly once cut
– Rind skin is fibrous and slightly slower to break down than flesh
Why size matters. A whole watermelon rind dropped intact into a compost pile takes 4-8 weeks to fully decompose. The same rind cut into 1-2 inch cubes breaks down in 2-3 weeks. Larger pieces work but they slow the whole pile down.
Why moisture matters. Watermelon rind adds substantial water to a pile. If your pile is on the wet side already, watermelon rind can push it into anaerobic territory. Compensate by adding extra browns (dry leaves, cardboard, straw) along with the rind.
A typical addition routine: Cut the rind into manageable cubes (about 1-2 inch cubes). Add to the compost bucket along with other kitchen scraps. Dump into the outdoor pile and bury under 2-3 inches of dry browns to balance the moisture and reduce critter attraction.
Watermelon rinds in worm bins. The high water content can overload worm bins. Add small amounts (one cup at a time), bury deeply in the bedding, and let the previous addition disappear before adding more.
Critter attraction: Watermelon rind is sweet and attracts fruit flies, raccoons, possums, and other wildlife if left exposed. Always bury under dry browns or in the pile interior. Wire-mesh cages or closed bins help in critter-prone areas.
Seeds: Watermelon seeds, like other cucurbit seeds (cucumber, squash), often survive cool home composting and can produce volunteer plants. Most home gardeners don’t mind volunteer melon vines; some find them valuable as a free crop.
Feeding Watermelon Rinds to Animals
For households with backyard chickens, ducks, pigs, goats, or rabbits — or for those with friends or community members who raise these animals — the rind is excellent feed.
Chickens and ducks. Both love watermelon flesh and rind. Cut the rind into manageable strips (the chickens can peck through; ducks gulp larger pieces). Provides hydration on hot summer days and a sweet treat. Limit to occasional treats, not a daily large portion — too much fruit can disrupt digestion or shift egg production.
A typical 5-bird chicken flock will pick clean a 5-pound watermelon rind in 1-2 hours of foraging.
Pigs. Pigs eat essentially all of the watermelon — rind, flesh, seeds, anything. Pig farmers in the South historically valued watermelon rinds as summer-feed supplement. A single pig can finish a whole rind from a 20-pound melon in under an hour.
Goats. Goats enjoy watermelon rind in moderation. Cut into manageable strips. The rind provides hydration and a sweet treat. Don’t feed large quantities — goats can overeat sweet foods.
Rabbits. Domestic rabbits can eat watermelon rind in small amounts. The rind has more fiber than the flesh, making it the safer choice (the flesh is high in sugar). Cut into small pieces; introduce gradually.
Horses. Watermelon rind is generally safe for horses in moderation. Cut into 2-3 inch pieces (smaller pieces can be choking hazards if the horse doesn’t chew properly).
Cattle and sheep. Many livestock farmers feed watermelon rinds as a summer supplement. Cattle eat them whole; sheep prefer smaller pieces.
What not to feed: Don’t feed the outer green skin if it has pesticide residue (rinse first or peel). Don’t feed moldy or fermented rind. Don’t feed rind that’s been salted (from pickling preparation) — too much salt is harmful to animals.
Where to find takers: Local farms, community gardens, urban chicken keepers, livestock-keeping neighbors. Many communities have informal networks where families with surplus produce or waste connect with farmers who can use it. Apps like Olio, Too Good To Go (in some markets), and local Facebook groups facilitate this.
A Combined Strategy
For households that consume a lot of watermelon in summer, a combined approach often works best:
-
Pickle a few jars when you have time and energy for canning. One pickling session yields enough jars to last through the year.
-
Compost the rest of the rind that you don’t pickle. Cut, balance with browns, bury in the pile.
-
Set aside some for neighbors who raise chickens or pigs if you have those connections. A whole rind that goes to a backyard chicken flock often produces more value (eggs, neighbor goodwill) than the same rind going to compost.
For a typical household consuming 5-15 watermelons over a summer (30-150 pounds of rind total), this combined approach can eliminate 80-95% of watermelon-rind waste and produce real value from each pound.
Regional and Cultural Notes
Southern United States. Pickled watermelon rind is a deep tradition. Many families have generational recipes. The product is sold at farmer’s markets and specialty stores year-round.
Caribbean. Some Caribbean cuisines pickle watermelon rind with hot peppers and lime for a distinct sharper flavor profile.
Asia. Watermelon rind is used in stir-fries, soups, and preserves in several Asian cuisines. In Chinese cooking, the white inner rind is sliced thin and used in cooling summer soups. In Korean cuisine, watermelon rind kimchi exists as a regional variant.
Mediterranean. Italian and Greek traditions include watermelon rind in some preserves and antipasto preparations.
Modern food movement. Reducing food waste is a contemporary interest, and watermelon rind has gotten attention from chefs like Dan Barber (Blue Hill at Stone Barns), Tamar Adler (writer), and Massimo Bottura who has popularized “lower hierarchy” ingredient use in fine dining settings. Watermelon rind has appeared on tasting menus at high-end restaurants in the past several years as part of waste-reduction culinary statements.
Practical Summary
Watermelon rinds are too useful to throw in the trash, and you have three good options:
- Pickle them for a year-round Southern condiment that pairs with everything from ham to cheese plates.
- Compost them with browns to balance the high moisture, cutting into cubes first for faster decomposition.
- Feed them to backyard chickens, pigs, or other livestock — yours or a neighbor’s.
For most households, the answer is some combination of the three. A few jars of pickled rind in the pantry. The rest going to compost or to a friend with chickens. None going to trash.
Beyond Pickling: Two Other Cooking Uses
For households interested in cooking with watermelon rind beyond pickling, two additional approaches work well:
Stir-fry or sauté. Peel the green skin, cut the rind into thin matchsticks (like julienned daikon radish), and stir-fry with garlic, ginger, soy sauce, and sesame oil. The rind takes on the flavor of the seasonings and provides a crisp-tender texture similar to cooked daikon or cucumber. A useful weeknight side dish that takes 8-10 minutes total. Works particularly well with Asian-style meals.
Watermelon rind chutney or relish. Cooked down with vinegar, sugar, ginger, and warming spices like cinnamon and clove, watermelon rind makes a savory-sweet chutney that pairs with grilled meats, cheese boards, and curries. Indian and Persian traditions have versions of this preparation. The chutney keeps refrigerated for 2-3 weeks or can be water-bath canned for shelf storage.
Watermelon rind candy. A more dessert-oriented use: cubes of rind boiled in heavy sugar syrup until they become translucent and candy-like. Stored in airtight containers, the candied rind lasts for weeks and works as a topping for ice cream, in fruit cakes, or as a snack. The method is closer to candied citrus peel than to a pickle.
A Final Honest Note
These uses for watermelon rind are real but require a few minutes of intentional handling. The default behavior of throwing the rind in trash is faster and easier. For most households, even adopting one of the three options (pickling, composting, or feeding to animals) for some portion of the rind is meaningful progress over the throw-everything-away default.
The 30-35% of a watermelon that’s traditionally been waste is in fact one of the most useful waste streams in a kitchen — easy to handle, multiple legitimate uses, and tradition behind every method. Worth the small effort to redirect from the trash bag.
