Seminole River Pumpkin Seeds

When to Plant Seminole Pumpkins are a warm-season crop through and through. Direct sow after your last frost date once soil has warmed to at least 65–70°F. In Florida and the Deep South, seeds can go in the ground anywhere from late winter through midsummer, with a fall planting window as well — just make sure you have 100 days before your first expected frost. In cooler northern climates, starting seeds indoors 2–3 weeks before your last frost gives the long season a helpful head start.

Starting Indoors Sow seeds about an inch deep in individual biodegradable pots to minimize root disturbance at transplant time. Keep soil warm — 75–85°F is ideal — and expect germination in 7–14 days. Harden off transplants over 5–7 days before moving them to the garden. Transplant out once nights are reliably warm.

Direct Sowing Plant 3 seeds per hill, about an inch deep, and thin to the strongest plant once true leaves appear. Give each hill a wide berth — these vines need room to do what they do. Rows should be at least 6–8 feet apart, and individual plants 2–3 feet apart at minimum.

Location & Soil Full sun is a must. Seminole Pumpkins historically climbed trees and fences to chase it, and your garden planting should reflect that spirit — give them something to climb or a wide open area to sprawl. Soil should be well-draining and amended with compost before planting. A raised hill or mound 8–12 inches tall improves drainage and warms up faster, giving the vines an early boost.

Watering Water at the base of the plant, not overhead — wet foliage is the main invitation for mildew issues. These plants are notably drought-tolerant once established, but consistent moisture during flowering and fruit development leads to better yields. Don't overdo it; they genuinely do well with less attention than most squash.

Pest & Disease Resistance This is one of the Seminole Pumpkin's biggest selling points. Where other squash varieties succumb to vine borers, Seminole Pumpkins keep right on growing — their tougher stems are far more resistant to borer damage. They also show strong natural resistance to downy mildew. Practice crop rotation year to year as a basic precaution, but don't be surprised if this is simply your most trouble-free squash.

Harvesting Fruits are ready when the stem turns brown and woody and the rind has hardened fully and reached its mature tan-orange color. Cut the stem a few inches above the fruit using sharp pruners rather than twisting it off — a clean stem helps the pumpkin store longer. Once harvested, cure in a warm, well-ventilated spot for a week or two before moving to long-term storage. In ideal conditions — cool, dry, good airflow — these pumpkins can hold for up to a year.

Young green fruits can also be harvested early and cooked like summer squash, and the yellow blossoms are a bonus harvest throughout the season.

Saving Seeds Seminole Pumpkin is open-pollinated and an excellent seed-saving variety. Since it belongs to the species Cucurbita moschata, it can cross with butternut squash and calabaza — isolate by at least a half mile if saving seeds for true-to-type offspring. Seeds are fully mature when the fruit stem has turned brown and woody. Scoop seeds from a fully ripe fruit, rinse well, and dry on a screen away from direct sunlight for 1–2 weeks. Store in a cool, dry place for up to 5 years.
