Our Picks at a Glance
How To Choose The Best Spaghetti Squash Seeds For Planting
Spaghetti squash is a warm-season crop that needs full sun and regular watering to thrive. Picking the right seed packet is about matching the seed count to your garden size and checking that the seeds are the type you want to grow.
Seed Type: Heirloom and Open-Pollinated
Heirloom and open-pollinated seeds mean you can save seeds from your harvest and plant them again next year. Non-GMO is the standard across quality seed brands, so look for those terms if you plan to grow the same variety season after season.
Seed Count and Germination
A big packet of 700 seeds suits a large garden or a planting project with friends. A smaller pack of 5 seeds is enough for a backyard patch. The fastest sprouters show growth within days, so check reviews for real germination reports.

In‑Depth Reviews
1. Spaghetti Squash Seeds for Planting – 5 Packs by Survival Garden Seeds
Our pick — over 4★ from 100+ verified ratings; the strongest balance of quality and price.
Five separate packs that sprout in under a week, for gardeners who want quick results.
These are heirloom, non-GMO Cucurbita pepo seeds from a family-owned American small business. The 5-pack format means you can stagger plantings or share with neighbors.
This variety is a vigorous vining plant that thrives in warm conditions with full sun. It works well in backyard gardens, raised beds, and larger growing spaces. The harvested squash has a thick rind that stores well for extended periods once properly cured, making it a solid winter storage crop.
The main trade-off is seed count — 5 pieces suits a modest garden but not large-scale planting. Some growers noted an occasional green squash that might be an accidental hybrid, though this doesn’t affect the edible quality. These seeds are open-pollinated, untreated, and quality tested for garden success.
Why gardeners love these
- Fast germination — sprouts in under a week
- Heirloom, non-GMO, open-pollinated seeds
- Low maintenance and attracts pollinators
What to consider
- Only 5 seeds per pack
- Occasional green squash may appear
Grab these for: a small backyard patch where you want reliable, fast sprouting with minimal fuss.
Think twice if: you need to fill a large plot — 5 seeds won’t go far.
2. Organic Squash Seeds (Winter Spaghetti) – Approx 20 Seeds – USDA Organic, Non-GMO, Open Pollinated, Heirloom, USA Origin (Pack of 2)
Certified organic seeds that sprout in just 2 days, for the cleanest possible harvest.
These seeds carry the USDA Organic Seal, meaning they’ve passed rigorous standards and been certified by a USDA Accredited agency. Each pack of 2 contains 20 seeds, giving you 40 total for a solid garden row. The seeds are packed for the current growing season and should provide high germination rates next year as well.
Germination is the thing everyone raves about here — the review pages sum it up: “I had sprouts in 2 days! Amazing!” Buyers report an 80% germination rate with strong, fast-growing plants suited to raised beds, gardens, and planters. The bright yellow vegetables have a mild, nutty flavor, making them a great pasta substitute.
For harvesting, the instructions recommend clipping the stem 3-4 inches above the squash once the rind is tough. Leave the squash in the sun for 10-14 days to cure naturally, then store in a cool, dry place. The premium packaging shows the plant variety on the front with instructions and plant facts on the back.
Standout trait: Certified USDA organic with a 40-count total across two packs, giving you more seeds than the 5-pack option above.
Reach for this if: you want certified organic seeds with fast, reliable sprouting and enough seed to fill a full row.
Look elsewhere if: you need a bulk quantity for a large farm — 40 seeds suits a home garden best.
3. Sustainable Seed Co Organic Vegetable Spaghetti Squash Seeds 1/4 LB ~700
A quarter-pound bounty of roughly 700 organic seeds for serious gardeners.
This is the bulk option, delivering approximately 700 seeds — a 140x gap versus the 5-seed pack from Survival Garden Seeds. That sheer volume makes it the clear choice for large gardens, community plots, or sharing with fellow gardeners. The seeds are organic, non-GMO, heirloom, and open-pollinated from a family-owned company focused on ethical, sustainable seed production.
These are annual Cucurbita pepo seeds that take 80 to 100 days to reach full maturity, so they are not intended to overwinter. They grow best in sandy soil with full sun exposure. Buyers reporting vigorous growth note the seedlings came up fast and looked healthy in the garden. One grower planted these alongside Butternut Squash seeds and found the spaghetti seedlings grew to double the size of the butternut.
The trade-off is that a home gardener with a small yard may find 700 seeds overwhelming. The larger quantity also means you should plan storage carefully to keep seeds viable for future seasons. For anyone serious about growing spaghetti squash in volume, this is the most economical route per seed.
Best for: serious gardeners and anyone planting a large area who wants organic, heirloom seeds at the lowest cost per seed.
Note: 80-100 days to maturity means planning your planting date matters for a fall harvest.
Choose this for: maximum planting capacity and the best value per seed of the three options.
skip it if: your garden only needs a handful of plants — you will have far more seeds than you can use.
Understanding the Specs
Germination Rate
This is the percentage of seeds that actually sprout. A high germination rate means more plants for your money. The fastest sprouts show growth within 2 days, while others take up to a week. Check reviews for real germination reports before choosing.
Organic vs Non-GMO
Organic seeds are certified by a USDA Accredited agency and grown without synthetic chemicals. Non-GMO means the seeds are not genetically modified. Heirloom and open-pollinated seeds let you save seeds from your harvest for next year’s planting.
