Growing Melons in Containers: Rewards and Realities

Container melon growing seems simple—controlled soil, measured inputs—but the author, a former field-scale grower, found it far more challenging than acreage. One failed plant means total loss; no "backup" vines to compensate.

Container Basics

• Varieties: Choose compact types: 'Minnesota Midget', 'Sugar Cube', 'Organic First Kiss F1', 'Organic Sivan F1' cantaloupes.
• Container size: At least 16 inches deep; 3+ cubic feet soil per plant. Half 55-gallon barrels work well (cheap, hold multiple plants).
• Trellising: Essential to keep fruit off ground and prevent vines sawing themselves on pot edges. Use pantyhose or onion/potato sacks to support fruit.

Keys to Success

• Pests/diseases: Choose resistant cultivars; fence out deer/groundhogs; healthy plants resist best.
• Fertilizing: Melons are heavy feeders. Potting mix nutrients exhaust mid-season. Supplement with balanced fertilizer, shifting from nitrogen to phosphorus/potassium as fruit sets.
• Watering: Tricky in containers. Author hand-watered with drip tray for occasional bottom-watering, avoiding overhead irrigation to prevent disease.

Field growing with composted manure remains easier, but container melons earn respect for the skill they demand.
