This squash starts green and ripens to yellow.
If your spaghetti squash is still green, don’t worry—this is actually part of its natural ripening process. Some spaghetti squash typically starts off green and gradually transitions to a vibrant yellow as it matures. However, this color change can vary in timing, especially depending on your climate, growing conditions.
This is because the plant relies on warmth and sunlight to progress through its ripening stages. If you’re in a climate with fewer sunny days or cooler temperatures, your squash might stay green a bit longer, needing extra time to reach full maturity. Best temperature for ripening is 70-80. Wait until the skin is dull and so hard you cannot pierce it with you thumbnail
On the other hand, warmer climates can accelerate the ripening process. Consistent sunshine and warmth give the squash the ideal conditions. If your season is winding down and the temperatures are dipping, consider leaving the squash on the vine for as long as possible to give it a chance to ripen fully. You might also bring it indoors to finish ripening off the vine, as some squash will turn yellow after harvesting if left in a warm spot with indirect light.
Patience is key—your green squash will transform into the golden yellow spaghetti squash you’re expecting, as long as it has the right time and warmth to finish ripening!
