Yellow Crookneck Summer Squash (55-60 Days)

Heirloom 1700s. This Native American summer squash is a very prolific heirloom with a buttery flavor and light yellow skin. Should be picked at 4-5” for the best taste. If you were to leave the squash on the plant until maturity they get large and have ornamental warted rinds ideal for fall decoration. 

20 seeds


Cucurbita pepo

Germination: 4-10 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 36-48" apart after last frost. 

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

Harvest: Check and harvest a few times a week. Cut or kindly twist off fruit, starting at a 3-4”.

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.

crookneck squash

this is the best crookneck I have ever grown. It outgrows the squash vine borer. Stems are tough enough to withstand some of the damage, and they also root where they touch the ground. I had given up on growing squash for years, until I discovered this old heirloom from y’all! And is has a fine flavor!

My Opinion of the Yellow Crookneck Summer Squash

I annually enjoy shopping at Pinetree - good products, good prices, easy ordering, quick shipping, etc. Relative to the Yellow Crookneck Summer Squash, I have not yet planted the seeds as it's been a relatively cool spring so far in Michigan. However, I plant these ever year and they are very prolific and great tasting, but one has to watch them grow on a near-daily basis as once they get too big, they become warted with a sharp distaste. Picked often and at about a 6" length, they are unbeatable in tenderness and taste!

Nice squash, but huge plant!

Having grown many varieties of summer squash over the years, I can honestly say I have never seen a yellow squash plant this big. It has an enormous number of leaves that I've had to thin out to let some light into the center of the plant. The squash itself is a nice size and has a very good flavor and texture.


crook neck summer squash

this is my go to for a summer squash. the best time to harvest it is when they just start getting seedy inside but the rind is still soft. I have converted many people to this squash because it actually has a flavor and some texture too. I have to plant a lot as I have a lot of garden buddies that I keep supplied with when we trade. I planted my last hills August 1st and started the massive harvest Sept 8th. these will keep me busy picking them until frost.
