- Water at the base of the plants to avoid wetting the foliage, which helps reduce the risk of diseases such as powdery mildew.
Fertilizing

Pest and Disease Management
- Regularly check for common pests such as aphids, cucumber beetles, and root-knot nematodes. Vigilance is key to maintaining a healthy crop.
- Utilize organic or integrated pest management strategies to effectively manage pests and diseases while promoting a beneficial insect ecosystem.
Harvesting
- Harvest cantaloupes when they have a sweet aroma and their skin color transitions from green to a golden hue. Regular harvesting encourages continued fruit production.
