Approximately 12-15seeds per gram. Cucurbita pepo Lot# SQ34106 Spaghetti Squash plants grow to 40-61 cm (16-24”) tall with trailing vines that can reach 1.2 m (4-8’) long. You can expect to grow 5-7 squash per plant that can weigh up to 3.1 kg (7 lbs.). Spaghetti squash have a thick cylindrical or oblong smooth shape and a hard shell that is ivory and changes to yellow when mature. Can be stored up to 4 months. Harvest before a frost.
Squash seedlings do not really transplant that well, but it can be done if you are careful. Start transplants at least 3-4 weeks before last spring frost. Sow 2 or 3 seeds 12 mm- 2.5 cm (½-1”) deep in pots. When the seedlings are 5-7 cm (2-3”) tall, select strongest seedling and thin to 1 plant per pot using scissors. Harden off seedlings gradually by cutting back on water and expose them to sunlight daily. Seedlings should have more than 2 to 3 true leaves prior to transplanting outside. Transplant once the soil is warm up to at least 15-21˚C (60-70˚F). Plant 2 transplants per hill. Space hills 2.4-3 m (8-10’) apart each way. If planting in rows space seedlings at 61-91 cm (24-36”) apart. Space 2.4-3 m (8-10’) apart.
Direct sow seeds into garden from late May to mid-June. Sow 3 or 6 seeds 12 mm- 2.5 cm (½-1”) deep into hills that are 2.4-3 m (8-10’) apart each way. Thin seedlings at 2 per hill.
Soil Conditions: Well worked rich, loose well-drained soil. Ideal pH: 5.5-6.5
Planting Depth: Sow seeds 12 mm- 2.5 cm (½-1”) deep.
Germination: 7-14 days.
Height at Maturity: Plants reach 40-61 cm (16-24”) tall. Trailing vines can 1.2 m (4-8’) long or longer.
Days to Maturity: Long season 90-100 days.
Watering: Spaghetti Squash has regular water requirements. Water slowly with 2.5-5 cm (1-2”) of water per week. Allow it to completely soak the soil 15-20 cm (6-8”) deep. This will ensure good growth, whether vegetables are grown in single hills or wide rows. The amount of rain that falls during the week will help supplement how much you should water your garden. Soil should remain moist. Avoid getting water on the leaves to help control diseases. Water in the morning if possible to allow leaves to dry if they do get wet. This will help in preventing leaf diseases. Decrease watering later in the season to encourage fruit to mature.
Sun/Shade: Full Sun
Spacing after Thinning: Space transplant 2-3 plants per hill that are 2.4-3 m (8-10’) apart, each way.
Additional Information Spaghetti Squash are best harvested when the rind turn to yellow with no hints of green. Complete the harvest before the first hard frost. Stems and vines will be hard and dry at harvest time. It is often easy enough to snap the fruit from the vine but try and leave a bit of the stem on the fruit to help preserve moisture. Do not carry the fruit by the stem either as it could easily snap off. Cure the squash in the sun or a dry location until stem shrivels. Do not wash squash that you intend to put up for storage.
