- Species and varieties: Crimson Sweet watermelon (Citrullus lanatus) is a popular variety known for its sweet, juicy flesh and vibrant red color. It is a type of watermelon that is widely grown and appreciated for its large size and excellent flavor.
- Hybrid or heirloom: Crimson Sweet watermelon seeds are typically heirloom seeds, meaning they are open-pollinated and have been passed down through generations without genetic modification. This variety is prized for its consistent quality and traditional taste.
- Pruning and training: Crimson Sweet watermelons do not require extensive pruning. However, it is beneficial to remove any weak or diseased vines to encourage the growth of healthy fruit. Training the vines to spread out can help maximize sunlight exposure and improve fruit development.
- Fertilization needs: These watermelons benefit from a balanced fertilizer, such as a 10-10-10 NPK formula, applied at planting and again when the vines begin to run. Additional side-dressing with nitrogen can be done when the fruits start to develop. Regular watering is crucial, especially during dry periods, but avoid overwatering to prevent root rot.
- Hardiness zones: Crimson Sweet watermelons are best suited for USDA hardiness zones 3-11. They thrive in warm climates and require a long growing season with plenty of sunshine.
- Climate requirements: These watermelons need a warm, sunny climate with temperatures consistently between 70-85°F (21-29°C). They require well-drained soil with a pH between 6.0 and 6.8. Adequate spacing and good air circulation are essential to prevent diseases and promote healthy growth.
