Planters Jumbo Melon
Planters Jumbo is a heat-loving cantaloupe that thrives where others struggle, developed specifically for growers who face unpredictable water conditions. These 4 to 5 pound melons mature in 80 to 89 days and produce sweet, deep orange flesh beneath a firm, netted rind. Hardy in zones 2 through 13, this open-pollinated heirloom resists powdery and downy mildew, making it both reliable and flavorful from mid-summer through early fall.

Highlights
The defining strength of Planters Jumbo is its stubborn resilience in challenging conditions. Market growers have long favored it because it produces consistently sweet fruit whether conditions are wet or dry, a rare trait that removes the guesswork from melon growing. Combined with solid disease resistance and the ability to thrive in containers, raised beds, or traditional garden rows, this variety delivers dependable harvests without fussy demands.
Common Uses
Planters Jumbo cantaloupes are enjoyed fresh, often cut into wedges or scooped into balls for fruit salads and desserts. The firm rind holds up well to storage and transport, making these melons suitable for meal prep and farmers market sales. Their sweet flesh also works beautifully in smoothies, granitas, and as a simple breakfast or snack on warm days.

Care Instructions
Transplant Outdoors
Transplant hardened seedlings outdoors after the last frost date, when soil temperature reaches at least 65 degrees Fahrenheit. Space plants 48 inches apart to give vines room to sprawl.
Direct Sow
Direct sow seeds outdoors after the last spring frost, when soil is warm. Press seeds into warm, well-draining soil at the appropriate depth and thin seedlings to 48 inches apart.
Harvesting
Cantaloupes are ready to harvest 80 to 89 days after planting. Look for a deep, netted rind and press the stem end gently; ripe fruit will slip easily from the vine with slight twisting. You'll also notice a sweet, fragrant aroma near the stem end when melons reach peak ripeness. Pick melons in the morning for best flavor and immediate enjoyment.
Pruning
Planters Jumbo's vining growth habit doesn't require heavy pruning, but you can selectively remove dead or diseased foliage to improve air circulation and reduce disease pressure. If growing in containers or tight spaces, gently guide vines along trellises or allow them to cascade, removing damaged stems as needed.
