Water deeply and consistently, especially during flowering and fruit development. Provide about 1–2 inches of water per week, but avoid overhead watering to prevent diseases. Reduce watering once fruits start ripening to improve sweetness and prevent splitting.

For best results, hand-pollinate flowers if pollinators are scarce. Simply transfer pollen from male flowers to female flowers using a small brush or cotton swab.

Cantaloupes are susceptible to pests like aphids, cucumber beetles, and squash bugs. Use row covers to protect young plants and apply neem oil or insecticidal soap as needed. Fungal diseases like powdery mildew can be prevented by ensuring good air circulation and avoiding overhead watering.

Cantaloupes are warm-season crops that grow best from direct seeding or transplants. Start seeds indoors 3–4 weeks before the last frost if growing in cooler climates, or directly sow seeds outdoors once the soil temperature reaches at least 70°F (21°C). Plant seeds ½–1 inch deep in well-draining soil and keep them moist until germination, which usually takes 5–10 days. For better germination, soak seeds in warm water for 12–24 hours before planting. If starting indoors, use biodegradable pots to minimize transplant shock when moving seedlings outdoors.

Cantaloupes need full sun and warm temperatures to thrive. Choose a planting site with loose, sandy, well-draining soil and a pH between 6.0 and 6.5. If planting in a container, use a pot at least 16–18 inches wide with good drainage holes.

When planting in the ground, sow seeds in small mounds or raised beds to improve drainage and warmth. Space plants 36–48 inches apart to allow vines to spread. For vertical growing, use a strong trellis and provide support for developing melons with slings made from fabric or netting.

Cantaloupes are heavy feeders and require nutrient-rich soil. Before planting, mix compost or well-rotted manure into the soil. Use a balanced fertilizer (such as 10-10-10) at planting and switch to a low-nitrogen, high-phosphorus and potassium fertilizer (such as 5-10-10) once flowers appear to encourage fruiting. Mulching around plants helps retain moisture and suppress weeds while maintaining soil temperature.

Since cantaloupes are warm-season annuals, they do not overwinter. At the end of the growing season, remove plant debris to prevent disease buildup. If growing in a greenhouse, maintain a temperature above 70°F (21°C) for continuous growth.

Cantaloupes take about 70–90 days to mature after planting. Signs of ripeness include a golden or yellowish skin tone, a sweet aroma, and the fruit easily detaching from the vine with a gentle tug.

To increase fruit quality, limit each vine to 3–5 melons by pruning excess flowers and smaller fruits. Also, trim back excessive vines to direct energy toward fruit development.

For best storage, keep harvested cantaloupes at room temperature until fully ripe, then refrigerate for up to 5 days. Cut melons should be stored in an airtight container and refrigerated.
