The classic picnic melon of perfect balance. ‘Crimson Sweet’ produces round fruits with light and dark green striping and vibrant red flesh bursting with sugary flavor. The texture is crisp and fine-grained, with a refreshing sweetness that defines the summer harvest.

Fruits average 20–25 pounds, with vines that spread widely and resist common diseases. Excellent for home gardens and market stands alike.

Choosing the Right Location:

Light Requirements: Watermelon - Crimson Sweet thrives in full sun. Select a location that receives at least 6-8 hours of direct sunlight daily.
Soil Requirements: Prefers well-drained, fertile soil with a pH of 6.0-6.8. Although adaptable to various soil types, it grows best in sandy loam soil enriched with organic matter.
Planting Seeds:

Timing: Sow seeds directly outdoors after the last frost date when the soil has warmed to at least 70°F (21°C). Alternatively, you can start seeds indoors 2-4 weeks before the last expected frost date.
Sowing Depth: Sow seeds 1 inch deep in hills or rows.
Spacing: Thin seedlings to 2-3 plants per hill, with hills spaced 6-8 feet apart. If planting in rows, space plants 3 feet apart with rows 6-8 feet apart.
Watering:

Initial Watering: Keep the soil consistently moist but not waterlogged until the seeds germinate, which typically takes 7-10 days.
Ongoing Watering: Once established, water deeply and regularly, especially during dry periods. Watermelons require consistent moisture, particularly when the fruits are developing. Avoid overhead watering to prevent foliage diseases and water at the base of the plants instead.
Temperature and Climate:

Preferred Temperature: Watermelon - Crimson Sweet grows best in warm temperatures ranging from 70-90°F (21-32°C). It requires a long growing season with plenty of heat.
Fertilization:

Feeding: Incorporate organic matter such as compost into the soil before planting. Use a balanced, all-purpose fertilizer at planting time and side-dress with additional fertilizer or compost when vines begin to run and again when fruits set.
Pruning and Thinning:

Thinning: Thin seedlings to prevent overcrowding, which can hinder growth and reduce air circulation.
Pruning: Not necessary for watermelons, but you can pinch off the growing tips of vines to encourage lateral growth and more fruit set if desired.
Mulching:

Mulch Application: Apply a layer of organic mulch around the base of the plants to retain soil moisture, suppress weeds, and regulate soil temperature. Black plastic mulch can be used to warm the soil and speed up growth.
Pest and Disease Management:

Common Pests: Watermelons can attract pests such as aphids, cucumber beetles, and squash bugs. Use insecticidal soap or neem oil to control these pests if necessary.
Diseases: Ensure good air circulation around the plants to prevent fungal diseases. Avoid overhead watering to minimize the risk of mildew and other fungal issues. Crop rotation and proper spacing can also help reduce disease incidence.
