How to Grow Cantaloupe

A freshly ripened cantaloupe straight from your own garden is one of the summer's greatest pleasures. There are hundreds of varieties of cantaloupe to choose from, but the classic Hale's Best, a popular melon with old-time growers, is one of the best. Whatever variety you choose, you can learn to prep the ground for planting, care for your budding melons, and identify common problems throughout the growing process to give you the best chance for success. See Step 1 for more information.

EditPrepping the Ground and Planting

1. Select a hardy variety appropriate for your climate. Cantaloupes, also known as muskmelons, are available in dozens of cultivated and heirloom varieties, and grow best in hot weather, at least 2-3 months of consistent warmth. Cantaloupes love very sandy and loamy soil with good drainage, and a pH of around 6.
   
   • Varieties good for cooler climates include Hale's Best, Sarah's Choice, and Eden's Gem. Varieties noted for their flavor include Hearts of Gold, Ambrosia, Athena, and Honey Bun.
   • Pay particular attention to the time to maturity listed on the seed package. Most of the time, you won't buy cantaloupe starts, you'll purchase seeds and start them yourself. On the seed package, pay particular attention to planting advice and information about keeping them safe, and pay particularly close attention to the length of time to maturation.
   • If you want to save cantaloupe seeds from a particularly-delicious melon for planting, scoop them from the flesh and soak them for two days in cool water, then drying them thoroughly on a paper towel. Store them in a clean jar in a cool, dark environment until you're ready to start your melons. While viable for around two years, it's usually best to plant seeds within the year.^[1]
2. Select an appropriate location for cantaloupe. The most important part of planting and growing cantaloupe is warm soil and enough space. The vines need some room to spread out, regardless of whether you plan on trellising or letting the melons mature on the ground, so you'll need a fairly wide bed, depending on how large a crop you're going to plant.
   
   • It's a common misconception and fear that cantaloupes will cross with other members of the same family, including cucumbers, other melons, squash, and pumpkins. They won't. Don't worry about planting your vining fruits in the same area of your garden plot. Most strange or bland-flavored cantaloupe is not the result of accidental cross-breeding, but the result of environmental factors or other problems.^[2]
3. Prepare the soil. Lay compost or well-rotted manure evenly on your planting bed to create a rich feeding area for the cantaloupe. 6-8 inches of well-tilled soil is appropriate, plus your fertilization matter.
   
   • Start cultivating soil by tilling the ground at least a foot deep, aerating and thoroughly mixing the rough soil, removing any rocks, twigs, or other hard bits. Mix in a thick layer of manure and a smaller layer of compost on top, replacing the earth you excavated. Cantaloupes grow best on mounds, slightly raised above the surrounding ground, so don't worry if you've created a big bulge in the ground.
   • If you want, it's common to cover the ground of your plot with plastic film or weed matting prior to planting, to speed the warming process of the soil. It's important to plant cantaloupe starts in warm soil to promote healthy growth.^[3]
4. Consider starting cantaloupe indoors. If you knew the exact date of the last frost of the season, planting cantaloupe would be a snap. Ideally, cantaloupes will be direct-sowed approximately 10 days before the last frost, earlier in warmer climates. Because that date is ever more difficult to determine, it makes starting your cantaloupe indoors a somewhat more grower-friendly method.^[4]
   
   • If you live in a cooler climate, start seeds indoors about a month before transplanting by sewing them in biodegradable seedling pots filled with rich planting soil. You won't be able to disturb the gentle root system created by the germination, so it's important to use a biodegradable pot, rather than terracotta cotta. Moisten the soil generously, but without standing water. Plants should have a few mature leaves before transplanting.^[5]
   • If you live in warmer climates, you can direct sow seeds when the soil temperature warms to at least 65 degrees to avoid poor germination.
5. In your plot, create mounds for planting. Cantaloupe should be planted on raised mounds in a row, with each hill about 12 inches (30.5 cm) apart from the next. Rows should be at least 4 feet (1.2 m) apart.
   
   • Some growers prefer trellising cantaloupe, training the vines up onto a trellis pole or wire as a way of keeping the melons off the ground. This typically only works for smaller melons. If you want to trellis your variety, make sure to save room for the trellising, discussed below.
6. Plant your cantaloupe. Wait for the ground to warm to at least , sometime after the final frost of the season. Depending on where you live, this may be earlier or later in the planting season.
   
   • If you started your cantaloupe indoors, plant your biodegradable pot in the middle of each mound, as close to the center as possible. Wet the soil generously during planting.
   • If you're direct-sowing seeds, drop 5 cantaloupe seeds about one inch deep, 18 inches apart, in hills about apart.

EditCaring For Canteloupe

1. Water the cantaloupe deeply and sparingly. Keep the soil around the young cantaloupe plants moist, but not standing in water. They should get around 1 or 2 inches a week. Cantaloupe will be very sensitive during periods of drought and may need additional watering, so use your judgment and keep a close eye on the plants to make sure they're growing and looking healthy.
   
   • Melons will take a while to set on the vine, but most of the sugary flavor in a melon can be determined from the leaves. Just because you don't see melons yet doesn't mean that you don't know anything about how they will taste. Pay attention to the quality and vigor of the leaves: they should be dark green, with stiff structure and and healthy color. Yellowish or spotted leaves may be a sign of dryness or disease.
   • It's typical for melon leaves to wilt significantly in the midday and stay wilted looking until the evening in extremely hot weather. This isn't necessarily a sign that you need to water the cantaloupe more, however, so look at the quality of the leaves, not the limpness.^[6]
   • Drip-tape can be quite effective in watering your melons, but you can also hand-water or do whatever is appropriate for the size of your plot and other planting projects. Water around the base of the vines and try not to get the fruit wet, when it sets.
2. Protect the fruits as they begin to grow. Whether you're growing new plants or have transplanted your starts, it's a good idea to cover your rows with floating row cover in order to keep them warm and protect them from insects. You can use small loops of chicken wire to create a tunnel, then drape your netting over the row.
   
   • It's important to remove the matting after the threat of frost has dissipated and blooms have started to form, so that pollinating insects can reach the blossoms.
3. Weed the area thoroughly before the vines start running. It's challenging to walk around the thick network of vines, much less to weed it. To give your vines the best chance at growth, try to weed aggressively in the first couple of weeks of growth, and let them grow big enough to get a head start and beat out the weeds as the plant matures.
   
   • One of the difficult things about growing cantaloupe directly from seed is that the budding cantaloupe plant looks an awful lot like clover, a weed that you'll want to pick. Because it would be a tragedy to pull your budding plant, try to mark your start with a plant card, or wait until it distinguishes itself from the clover to start pulling weeds.
4. Consider trellising cantaloupe. Depending on how you've set up your growing patch, it may be appropriate to trellis your melons so they can grow off the ground. A fence-style trellis set low to the ground is the most effective for growing cantaloupe.
   
   • To train the vines, start by planting poles high at each mound in your melon row. You can use metal wire, planks of wood, thick twine, or any other available supplies to connect the poles and provide something for the melons to cling to. Train the vines up along the
   • To support the fruit, give them something to rest on or in to lessen the load on the vines. Place the fruit on raised mulch beds or pedestals like upside down cans or pots. You can cover the fruits if they are under attack by animals, such as ground hogs.
   • When your vines start fruiting, melons seated directly on the ground are more prone to rot and being picked off by critters. If the weather becomes somewhat damp, trellising is a good way to keep your melons protected from harm, especially in the latter stages of the growing season, but it's not super-necessary. Do, however, consider raising your melons off the ground level to protect them as then vine-ripen.
5. Fertilize plants periodically. During the growth process, its somewhat common to use a nitrogen fertilizer on plants that have not bloomed, or seem to be moving slower than other plants. Lining some coffee grounds around the root system can be an effective way of waking up the plant.
   
   • It's also common to fertilize cantaloupe with a higher potassium and phosphorus fertilizer after the blossoms have opened, though long time deposits of phosphorus fertilization can be environmentally hazardous. try to avoid weed killers and other chemical additives, line organic matter like compost or manure around the root system if they're lagging.
6. Withhold some water just before the cantaloupe reaches full ripeness. Too much watering can dilute the sugar content in the melon as it ripens and affect the flavor of the fruit. It's common to hold back on your watering in the last week before you harvest the melons.
   
   • When a cantaloupe is ready to pick, the stem will start cracking slightly where it meets the stem. It's overripe when it falls off completely.^[7] It's also common that you'll start smelling the distinctive musky smell of a ripe melon when you're near the patch. If you can smell cantaloupe, they're ready to pick.
   • Most varieties of cantaloupe will ripen within 4 weeks of appearing on the vine, though pay attention to the guidelines of the particular variety you're cultivating for more specific instructions.

EditTroubleshooting Cantaloupe Problems

1. Learn to recognize common pest infestations. Because they lay around the ground, melon vines are particularly susceptible to pests like insects, mites, and leaf miners. To keep from worrying, you can learn to recognize common problems and figure out whether or not you've got a serious problem.
   
   • Root knots and swelling mean nematodes, a significant problem that you won't be able to take care of this season. Pull up your plants and sew some cereal rye into the soil to cleanse it.
   • Stickiness and wilting mean aphids, which can be treated with Theodan or other organic insecticides like essential oil/olive oil mixtures.
   • Leaf tunnels and trails mean leaf miners, which isn't something to worry about. They shouldn't affect the fruit significantly.
   • Yellow webbed leaves mean spider mites, meaning that plants will need to be removed, if the small red mites are significant enough.^[8]
2. Recognize the symptoms of common blights. Grown and watered properly, your cantaloupe should be fine most of the time. Occasionally, though, ground-vining fruit are susceptible to blights and diseases that can ruin crops if not treated immediately. You can learn to recognize the most-common varieties of blight, so you can pull up the plants and save your other crops, or start a fungicidal regimen, depending on the severity.
   
   • Yellow spots with downy undergrowth signify downy mildew. This is sometimes treated with chlorothalonil, or other organic-based wide-spectrum fungicide, though it shouldn't be necessary for most gardens. Proper trellising of vines should help circulate air and eliminate the possibility of mildew.^[9]
   • Broken stems emitting amber-colored liquid means gummy sap blight. This is a soil-based blight, which means the crop will likely die this season, but you can treat sap blight by rotating varietals around your plot, and possibly using a selective fungicide.
   • Fruit rot after rain means southern blight. In regions with heavier soil, this is a common problem. Avoid over-watering and mulch between the plant and the soil to prevent rot.
3. Learn why vines sometimes won't set fruit. After going to all the trouble to prep your ground and start your cantaloupe, there's nothing more frustrating than a mess of vines that never sets any melons. Learning from this experience, though, can help ensure that you'll have fruiting vines in the future. Most fruiting problems are the result of one of two things:
   
   • A lack of pollinating insects can result in healthy-looking vines that never set. Cantaloupe vines produce male and female flowers, and pollination between them is necessary for fruiting. If you're growing cantaloupe in a greenhouse, or live somewhere that bees are scarce, you might need to pollenate by hand.
   • Improper ground temperature will force the plant to only produce male flowers, which makes it difficult to fruit, even if pollinating insects are very present. Make sure you wait to put your plants in when the soil is around .
   • If your melon plants struggle to produce, but you're doing everything by the book, try tilling some cereal rye in plots you plan on growing in for next season about a month before putting your plants in the ground.

EditTips

• Some gardeners suggest removing all but one growing fruit from a cantaloupe vine every 2 weeks. This way the vine can concentrate on the one fruit, making it sweeter.

EditWarnings

• Cantaloupe vine leaves can be attacked by insects and fungus. The quality of the leaves contribute greatly to the sweetness of the fruit. Ensure that the leaves of the vines are in good condition.
