Polaris Winter Squash (F1 Hybrid, 100 Days)

There is nothing like opening up the bright orange interior a butternut squash in the cold of winter, bringing back the memories of the summer season. A traditional butternut squash with medium sized, 4-5 lb. fruits. The vigorous plants produce at least 4-5 uniform fruits per plant. 

15 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 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 last frost when 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 which can shorten storage life. Cure for 7-10 days in the sun to harden the rind and increase storage quality. Wipe any debris off skin before storing 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.

with compost tea. Select the more compact varieties if your space is limited.

Have not planted yet.

Love your selection of seeds. Wow, I can tell you my lettuce is up and growing. Hope to have a early harvest. I seem to plant for the 6 neighbors and they love your lettuce too. Thank you for your input on seeds.

Polaris Winter Squash

Excellent. I have grown Polaris for the past two seasons. It is far and away the best butternut variety I have grown. My wife and I harvested at least two dozen mature squash from the planting in our garden plus some "wild-sown" plants in a waste area of our back pasture. In addition to its productivity, Polaris is a great winter keeper. We are still (mid-March) using unspoiled squash from last fall's harvest -- and we don't have a root cellar!

Best keeper ever!

Good butternut type, but not outstanding. These were nice size and very productive. Amazingly, we still have 4 from 2019 and it is now June 2020. I must have hardened them perfectly. The flavor did improve with time (or as winter drug on, garden grown winter squash became much more a treat). Just had a couple this week and they are still good. Starting to dry out a bit, but wow - what a keeper. The only ding on these are that they are not outstanding on flavor. Still will plant them again just to have squash in spring!

Polaris exuberance!

I grow this variety every year for flavor, texture, and reliability. I usually get 12-15 squash from a three-plant hill. Today I picked 38 good squash, and there are stil 8-10 not quite ripe., from the usual hill. They obviously flourished in the high rainfall summer we've had this year.
