Description
Watermelon Crimson Sweet is a reliable favourite, that delivers exactly what its name promises: deep crimson flesh, an irresistible sweetness, and that quintessential juiciness that makes every bite a delight.
The fruits are typically large, averaging between 9 to 14 kg, with a sturdy, slightly striped rind that transitions from green to a duller shade when ripe. Inside, the flesh is a vibrant red, fine-textured, and most importantly, bursting with that unmistakable watermelon sweetness. Watermelon Crimson Sweet remains a benchmark for flavour, striking the perfect balance between sugar and water content.
The vines are vigorous, spreading generously, which is part of what makes this watermelon such a productive grower. Each plant can yield multiple fruits, so a few seeds go a long way in filling a summer table.
Another appealing aspect of Watermelon Crimson Sweet is its versatility. Of course, it’s perfect for eating fresh, sliced straight from the fridge or tossed into a fruit salad but its high sugar content also makes it excellent for juicing, sorbets, or even pickling the rind if you’re feeling adventurous.
It’s a no-nonsense watermelon that does what it’s supposed to do, grow big, sweet, and juicy. There’s a reason this variety remains popular, it simply works. So whether you’re a seasoned gardener or just starting out, Watermelon Crimson Sweet seeds offer a dependable way to bring a taste of summer to your backyard.

Climate and Seasonal Timing
- Temperature Requirements: Watermelons require temperatures above 20°C for germination and optimal growth. Ideal growing temperatures range between 21°C and 35°C.
- Planting Seasons: See climate guides on product description.
- Frost Sensitivity: Ensure all threat of frost has passed before planting. Use protective covers if unexpected cold snaps occur.
Site Selection and Soil Preparation
- Sunlight: Choose a site with full sun exposure. Watermelons require at least 8-10 hours of sunlight daily.
- Soil Type: Prefer sandy loam that is rich in organic matter. Heavy clay soils can be amended with compost or sand to improve drainage.
- Soil pH: Maintain a soil pH between 6.0 and 7.5. Conduct soil tests and amend soil with lime if the pH is too low.
Planting Techniques
- Direct Seeding vs. Transplanting: Direct seed watermelons in the ground or start indoors and transplant. Transplanting can give plants an early start.
- Spacing: Space mounds about 75 cm apart.
- Isolation from Wind and Weeds: Use windbreaks or plant near natural barriers. Employ mulch to suppress weeds.
Watering and Irrigation
- Initial Watering: Keep soil consistently moist but not waterlogged, especially during germination and initial growth.
- Drip Irrigation: Use drip irrigation to deliver consistent moisture and minimize fungal diseases associated with overhead watering.
- Reduced Watering at Fruit Maturation: Gradually decrease watering as fruits start to mature to concentrate sugars and improve sweetness.
Fertilisation and Nutrient Management
- Initial Fertilisation: At planting, use a balanced slow-release fertiliser with emphasis on potassium for fruit development.
- Supplemental Feeding: Apply a side dressing of compost or additional fertiliser throughout the growing season, focusing on nitrogen during vine growth, and phosphorus and potassium when fruits start to develop.
Pest and Disease Control
- Common Pests: Monitor for aphids, cucumber beetles, and cutworms. Utilize organic pesticides or companion plants for natural deterrents.
- Diseases: Practice crop rotation to reduce fungal diseases like powdery mildew. Use resistant varieties when available. Ensure proper airflow and sunlight penetration by pruning leaves if necessary.
Companion Planting
- Marigolds: Deter nematodes with their strong scent.
- Radishes: Protect against cucumber beetles and enhance soil health.
- Corn: Acts as a natural windbreak and provides shade for younger plants.
Avoid Planting With:
- Potatoes: They compete for nutrients and attract similar pests.
- Other Cucurbits: Avoid planting near cucumbers and zucchinis to prevent cross-attraction of pests and diseases.
Harvesting
- Timeframe: Typically, watermelons are ready to harvest about 80 days after planting, depending on the variety.
- Indicators of Ripeness: The watermelon should have a hollow sound when tapped, the underside will turn a creamy yellow, and the tendril near the fruit stem will dry out.
