Dealing with Unripe Spaghetti Squash in Fall

Introduction

Spaghetti squash that stays green into October may not fully ripen, but it can still be used.

Why Squash Stays Green

Cool temperatures and shortening days halt ripening. Squash will not ripen off the vine once picked.

Eating Quality of Unripe Squash

Unripe winter squash is usually bland and watery. It's edible but not flavorful.

Leaving on Vine vs. Picking

Leave squash on the vine as long as possible, covering with garden cloth if frost threatens. If vines are dying and no ripening occurs, pick before hard frost—storage life will be shorter.

Conclusion

Green spaghetti squash in fall is best left on the vine; if it must be picked, use it soon and don't expect long storage.
