Days to Maturity

When growing spaghetti squash, the first thing to look for is the days to maturity listed on the seed packet. (Read Is An Onion A Vegetable)

Most spaghetti squashes are ready in 90 to 110 days. The maturity dates are calculated based on the number of days since you planted the seed.

Until that time, you have little worry of when to harvest. Your squash will be ripe in late summer, usually late September, for most northern gardeners.

Remember that the days to maturity shown on the seed pack correspond to when the first fruit ripens. The other squash fruit can ripen at different times, and some can take another month before you pick ripe spaghetti squash.

Fruit Color Change

When to pick spaghetti, squash plants can be seen from the skin. It will change color from a creamy white to a fully ripe golden yellow color.

It is unripe if the skin of the squash has uneven color, such as green spots or streaks, or if the squash is half yellow.

The squash is ripe for plucking when it has a matte, non-shiny appearance. If the squash skin is shiny, it is immature and requires additional time in the garden until it is fully ripe.

As the season progresses and your squash matures, the vines and leaves around your squash begin to die off and get dry completely before they turn brown; now is the time when to pick spaghetti squash.

The fingernail test is the last and most reliable way of determining when to pick spaghetti squash. The skin of an immature spaghetti squash will be soft.

If you leave a mark on the skin or puncture it, the spaghetti squash will take longer to harvest.

The hard, tough skin of fully ripe winter squash makes it difficult to mark or puncture with a fingernail. However, keep in mind that an overripe squash will have mushy spots and a soft, and the skin of the squash is easily marked.

You will also find the harder outer rind is one thing that differentiates these from summer squash.

How to Harvest Spaghetti Squash

You can let your spaghetti squash ripen off the vine if you’re anticipating an early winter frost or want to pick it before it’s entirely ripe.

It’s easy to harvest spaghetti squash. However, it’s critical to use a sharp knife or a pair of sharp garden pruners.

It’s crucial to leave 3 or 4 inches of stem attached when harvesting spaghetti squash.

Leaving at least 3 inches of stem attached to the squash prolongs storage and prevents bacteria from entering and rotting it.

When the spaghetti squash is ripe, clip it from the main vine and bring it inside to eat or cure for store.

Spaghetti squash should be rinsed and dried. To ripen, place it in a warm, sunny position. If there are any green areas on the squash, make sure they face the sun.

You may need to rotate or move your winter squash slowly to ensure that it ripens. Then, when it’s ready and ripe, it’ll develop a wonderful golden yellow color.

Overview of squash harvest

  1. When the color of the spaghetti squash changes to golden yellow, it’s time to harvest. Harvesting spaghetti squash with a green tinge is not recommended, as the green shows that the squash isn’t ready to be picked from the vine.
  2. Use your fingernail to scratch the rind. Allow the rind to ripen for a few more days if it is soft and readily scratched. After that, the flesh should be hard and resist scratching.
  3. Using garden shears or pruners, clip the stem off the spaghetti squash.
  4. Pulling the squash from the vine may cause the stem to get dislodged. Because removing the stem causes the squash to rot, leave a 2- to 3-inch length.

Cure Spaghetti Squash for Storage

Curing is the last step before putting your squash away for the winter. Curing allows the skin to complete the final hardening process, extending its storage life.

Wash and dry your ripe spaghetti squash before starting to cure it. Next, clean the squash using a bleach solution (ten percent bleach, ninety percent water) or white vinegar. Bacteria will be killed, and mildew will be removed using either of these approaches.

Then place your squash in a warm, dry location, such as a garage or a covered patio.

Temperatures of 80 to 85 degrees Fahrenheit are optimal for curing (26 to 30 degrees Celsius). Allow 10 to 14 days to cure spaghetti squash before putting them in their long-term storage place.

Storing Spaghetti Squash

The ideal temperature for storing spaghetti squash is between 50- and 55-degrees Fahrenheit (10 to 13 degrees Celsius). So, you’re looking for somewhere dark and dry to hide.

Basements that aren’t heated and insulated garages are both wonderful options. Just make sure your spaghetti squash doesn’t freeze, as this will hasten their decomposition.

Avoid stacking spaghetti squash on top of each other. Instead, it’s best if they’re laid out in a single layer, preferably without touching.

Air circulation is impeded when squash are stacked on top of each other, and rot can quickly spread to other squash.

Check your squash weekly for signs of deterioration or rot while it’s in storage, and eliminate any squash that displays signs of deterioration or rot.

Although spaghetti squash can be stored for a few months (3 to 6 months), it does not keep as well as other squashes and should be used as soon as possible.

You may also make your spaghetti squash and freeze it in serving-size sachets for up to 8 months.

Storage Preparation

Cleaning the squashes to remove any mold, mildew, dirt, or dust is necessary before storing your harvest. Wipe off the entire rind with a disinfection solution made up of 10% bleach and 90% water. Before you store spaghetti squash, make sure it is dry completely.

If you’re cooking spaghetti squashes, the noodles can be frozen and kept for up to 6 months. Before freezing the vegetable noodles, prepare them by cooking the squash, allowing it to cool, and then chill it for at least 12 hours.

After that, drain any excess moisture and dry the noodles before freezing. Precooked noodles can be stored in plastic freezer bags. (Read White Spots On Squash Leaves – What To Do)

Keep in mind that the moisture in the fridge accelerates the decomposition of winter squash.

Avoid storing a full spaghetti squash in the refrigerator unless it is firmly covered to prevent moisture from getting to it. It will last 2-5 days in the fridge if you cut up a raw squash and securely wrap the remaining pieces to keep the moisture out.

After harvesting and cutting, you can keep the seeds for the following year. Thus, you’ll get more squash to harvest at no extra cost of seeds.
