The All Sweet Watermelon is a quintessential summer fruit, known for its elongated shape, striped green rind, and deep red, ultra-sweet flesh. Each melon typically weighs between 25 to 30 pounds, making it a true heavyweight in the garden. This variety is seeded, but the seeds are small and easily removed. The flesh is crisp and juicy with a high sugar content, making it a favorite for fresh eating.
The vines are vigorous and sprawling, often requiring ample space to thrive. Large, lobed leaves protect the fruit from sunburn, and bright yellow flowers attract pollinators like bees. All Sweet is a standard in watermelon breeding programs due to its resistance to fusarium wilt and anthracnose, as well as its excellent shelf life and transportability.
Watermelons trace their origins back over 5,000 years to the Kalahari Desert in Africa. Ancient Egyptians even depicted them in hieroglyphs and buried them with their pharaohs as a source of hydration in the afterlife.
The All Sweet variety was developed in the mid-20th century in the United States as a market-friendly cultivar, designed for both home gardeners and commercial growers. It quickly gained popularity due to its reliable yield, disease resistance, and classic sweet flavor that recalls heirloom watermelons.
All Sweet Watermelon seeds
Seed-starting mix or well-draining soil
Seed trays or peat pots (optional for indoor starting)
Compost or organic fertilizer
Garden space or raised bed (at least 6–8 ft. per plant)
Mulch (e.g., straw or black plastic)
Watering can or hose
Trellis or support (optional, but usually grown on ground)
No special scarification is needed, but for faster germination:
Soak seeds in warm water for 12–24 hours before planting.
Ideal soil temperature: 75°F to 90°F (24°C to 32°C)
Germination time: 4–10 days
Do not plant seeds in cold soil; they will rot or fail to sprout.
Choose the Right Location:
Pick a spot with full sun (6–8 hours minimum daily) and well-drained, sandy or loamy soil.
Soil pH should be 6.0 to 6.8.
Starting Seeds Indoors (optional):
Start seeds 3–4 weeks before last frost date.
Use biodegradable pots to avoid disturbing roots when transplanting.
Direct Sowing Outdoors:
After the last frost and when soil has warmed to at least 70°F, sow seeds 1 inch deep, in mounds or rows.
Space mounds 3–4 feet apart with 6 feet between rows.
Watering:
Keep soil consistently moist during germination.
Once established, deep water once a week. Avoid watering leaves or fruits to prevent rot and mildew.
Feeding:
Fertilize at planting with compost or a balanced 10-10-10 fertilizer.
Switch to high-phosphorus and potassium fertilizer once flowers appear.
Mulching:
Apply mulch to retain moisture, suppress weeds, and warm the soil.
Black plastic mulch is especially effective for early season planting.
Pollination:
Watermelons require insect pollination. If fruit isn’t setting, hand-pollinate using a brush or gently rubbing male and female flowers together.
Pest & Disease Control:
Watch for cucumber beetles, aphids, and squash bugs.
Use row covers until flowering starts, and apply neem oil if needed.
Avoid overwatering and rotate crops to reduce fungal diseases.
Harvesting:
Harvest 85–100 days after planting.
Signs of ripeness:
Tendril nearest the fruit turns brown and dry
Underside of melon turns creamy yellow
Deep, hollow sound when tapped
Cut fruit with shears or knife to avoid damaging the vine.
Watermelons are 92% water – no wonder they’re the go-to summer hydration snack!
