How to Grow La Estrella F1 Calabasa Pumpkin

La Estrella is a Cucurbita moschata F1 hybrid, and that species designation is the first thing to understand about growing it. Moschata varieties are built different. Their stems are thicker and denser than C. pepo or C. maxima, which makes them significantly more resistant to squash vine borer damage. In Kansas and across the humid Midwest, that trait alone makes them worth growing.

Here is what you need to know to get a strong crop.

Starting Your Seeds

La Estrella needs warmth to germinate well. Soil temperature should be at least 70 degrees F, ideally 75 to 85 degrees, before you direct sow or transplant. In Kansas, that means waiting until late May or early June for direct sowing, or starting indoors 3 to 4 weeks before your last frost date if you want a head start.

Sow seeds 1 inch deep. Germination typically happens in 7 to 14 days at proper soil temperatures. At 65 degrees or below, germination slows dramatically and seeds can rot before sprouting. Do not rush the season.

If starting indoors, use 4-inch or larger cells. Squash roots resent disturbance. Transplant once the first true leaves appear, being careful not to disturb the root ball.

Soil and Site

La Estrella is a vigorous grower. It wants rich, well-draining soil with a pH of 6.0 to 6.8 and plenty of compost and aged manure worked in before planting. A shovelful of finished compost per planting hole makes a real difference.

Choose a full-sun location with at least 8 hours of direct sunlight per day. Moschata vines are heat-tolerant and actually perform better as summer temperatures rise, making them well-suited to the Kansas growing season.

Spacing and Training

Space plants 4 to 6 feet apart in rows 8 to 10 feet apart. The vines will run 10 to 15 feet or more at full growth. A cattle panel tunnel or sturdy trellis works well if you are growing vertically. La Estrella fruits average around 10 lbs, so any vertical support needs to be strong enough to hold the weight. Use cloth slings or old nylon stockings tied to the trellis to cradle developing fruits.

For ground growing, let the vines sprawl. Pinch off the growing tip after 2 to 3 fruits have set on each vine to direct energy into sizing up the fruit you already have.

Watering

Consistent moisture is important during germination, transplanting, and fruit set. Once the vines are established, La Estrella handles dry spells reasonably well, but regular deep watering at 1 to 2 inches per week produces better fruit size and yield.

Water at the base of the plant, not overhead. Wet foliage encourages powdery mildew, which moschata tolerates better than other species but still benefits from avoiding.

Vine Borer Resistance

As a Cucurbita moschata variety, La Estrella has natural resistance to squash vine borer (Melittia cucurbitae). The thick, hard stems of moschata varieties are more difficult for borer larvae to penetrate compared to the softer stems of C. pepo summer squash and zucchini.

Resistant does not mean immune. In areas with heavy borer pressure, it is still worth monitoring for adult moths in late June and July. Row cover during the egg-laying period adds an extra layer of protection. For more detail, see our Squash Vine Borer Prevention Guide.

Harvest and Curing

La Estrella takes approximately 125 days from transplant to harvest. The fruits are ready when the skin has hardened and the stem begins to dry and cork over. The coloring, ranging from green to tan to red-orange, deepens and intensifies as the fruit matures.

Cure harvested fruits at 80 to 85 degrees F with good air circulation for 10 to 14 days. Curing toughens the skin, heals any surface scratches, and dramatically improves storage life. Properly cured La Estrella squash can store for 3 to 6 months in a cool, dry location.

In the Kitchen

La Estrella is a Calabasa-type squash, the same style of tropical pumpkin used throughout Latin America, the Caribbean, and South America. The flesh is sweet, smooth, and firm with a rich flavor that intensifies when roasted. It holds its shape in soups and stews without turning mushy, purees beautifully for pies and soups, and makes excellent tamales, rice dishes, and curries.

Cut the squash in half, scoop the seeds, brush with oil, and roast cut-side down at 400 degrees F until tender, about 45 to 60 minutes depending on size. The flesh scoops cleanly and freezes well.

Seed Saving Note

La Estrella is an F1 hybrid. Seeds saved from the harvested fruit will not grow true to the parent. For reliable seed saving, consider our open-pollinated moschata varieties like Seminole Pumpkin or Long Island Cheese Pumpkin.
