Cuban Neck Pumpkin: Growing the Caribbean Heirloom Crookneck in Kansas
By Autumn Prairie Pumpkins
Cuban Neck is one of those Caribbean heirloom varieties that looks almost comically oversized, a massive crookneck squash with a long, curved neck and a bulbous seed cavity at one end. It can reach 15–25 lbs at full maturity, and the long neck is nearly all solid flesh. If you've ever processed a butternut and wished the neck section was twice as long, Cuban Neck is your variety.
This is a Cucurbita moschata heirloom that's been grown throughout Cuba and the Caribbean for generations. The tropical origins mean it's bred for extreme heat tolerance, and Kansas heat doesn't faze it. The moschata genetics provide the vine borer resistance we count on for all our varieties. The crookneck shape makes processing a dream: slice the neck into uniform rounds, peel, and you've got consistent squash pieces without dealing with a seed cavity until the very end.
Why Cuban Neck Works in Kansas
The Caribbean and central Kansas share one key trait: summer heat. Cuban Neck was selected under tropical conditions where temperatures routinely exceed 90°F for months, our Kansas summers are right in its comfort zone. The thick moschata stems resist vine borers, and the vigorous, spreading vines produce abundantly even in challenging conditions.
Days to maturity run 100–115 days. With a mid-May planting in central Kansas, you're looking at a September harvest, plenty of time in Zone 6b. The plants are large and vigorous, so plan space accordingly.
K-State's squash vine borer guide (MF3309) covers Kansas growing practices applicable to all moschata varieties including Cuban Neck.
How to Grow Cuban Neck in Kansas (Zone 6b)
Starting Seeds
Direct sow mid-May after soil hits 65°F. Plant 1 inch deep, 2–3 seeds per hill, thin to strongest plant. Cuban Neck germinates quickly in warm soil. Starting indoors 3 weeks early works if you want a head start on the longer maturity window.
Spacing
8–10 feet between plants. These are big vines that produce big fruit, give them room. Train vines in one direction along a row to manage the sprawl. Not a candidate for small gardens or containers.
Soil and Fertility
Rich, well-drained soil with generous compost. pH 6.0–6.8. Heavy feeder, large fruits require consistent nutrition. Side-dress with nitrogen when vines run, then back off at flowering.
Watering
1.5–2 inches per week during fruit development. Drip irrigation preferred. The large leaf canopy may wilt on hot afternoons even with adequate soil moisture, check soil before adding water.
Harvest and Storage
Harvest when the skin is uniformly tan-buff and hard. The stem will be dry and corky. The long crookneck may rest on the ground, slip straw underneath to prevent bottom rot. Cut with 4 inches of stem. Cure 2 weeks in a warm, dry area. Cuban Neck stores 4–6 months with proper curing.
Cuban Neck in the Kitchen
In Caribbean cooking, Cuban Neck is used in everything from pumpkin soup to flan de calabaza. The flesh is deep orange, dense, and sweet, very similar to butternut but available in much larger quantities per fruit. The long neck is solid flesh that slices into perfect rounds for roasting, soups, and stews.
Roast rounds at 400°F with olive oil and cumin for a Cuban-inspired side dish. Puree for soup. Cube for curries and stews. The flesh holds its shape well during cooking, making it versatile across cuisines.
Saving Seeds
Cuban Neck is open-pollinated. Save seeds from the bulb end of fully mature fruits. Scoop, rinse, and dry 2–3 weeks. Cross-pollinates with other Cucurbita moschata, isolate for seed purity.
