Autumn Frost Winter Squash (F1 Hybrid 100-105 Days)

Unique, round and stocky, deeply ribbed butternut type squash. Ripens to dark tan skin with a frosty overlay. This eye-catching squash has a rich butternut flavor and stores well up to 4 months. Fruits grow to 5-7” high by 5-6” wide. High resistance to Powdery Mildew.

 10 seeds



Cucurbita moschata

Germination: 7-10 days

Germination Temperature: Optimum soil temperatures 70-85ºF

Seed Sowing Depth: 1/2-1" deep

Sowing Indoors: 3-4 weeks before the last frost. Provide 70-85ºF soil temperature. Sow 2-3 seeds per cell/pot. Sowing into individual biodegradable peat/cow pots reduces root damage when transplanting. Transplant after last frost, 36-48" apart. 

Sowing Outdoors: Sow after the last frost when the soil temperature is over 70ºF. Sow a few seeds every 36-48". 

How much does a packet plant: 12-15 foot single row, 3-5 hills

Harvest: Before heavy frost. Determine ripeness when the skin has turned color and becomes dull dry. You will be unable to create a dent when pressing your thumbnail into it. Leave two inches of the stem on the squash and manage carefully so there is no damage that can shorten storage life. Cure for 7-10 days in the sun to harden the rind and increase storage quality. Wipe any debris off the skin before storing it in a cool dark place with 50-55ºF temperatures and 50-65% humidity.

Tips: Plant in fertile soil, amended with compost or well-rotted manure, and keep well watered. They benefit from growing on black plastic and by using row covers for weed, insect control, and more rapid growth.

Fine squash

Requires warm soil for germination, not great germination. I got >20 squash from 4 plants. Powdery mildew resistant, a good thing in our area. Great tasting. One squash feeds 2 to 4 people easily. Still have them in February. Good keeper.

Tasty and productive

Excellent germination. The vines were extremely productive, many squash per vine, couldn't get an exact count though. Some variation in size; let them on the vine until fully beige with a "frost" overlay. I would consider those in the photo not ripe enough. Heavy vine borer pressure here but did not see damage on AF. Nice orange interior- very similar to butternut--excellent taste. I grew 6 plants (with several other varieties) and had so many of these, I've had to give many away! Will grow 3 plants next year. Very fertile garden, southeastern PA. Used aged horse manure/TomatoTone for fertilizer.
