Spaghetti squash is one of my favorite types of winter squash to grow – I love the pasta-like consistency the most! Delicious in a lasagna or boiled and topped with butter and salt, these squashes also tend to be one of the last things to harvest from my garden.

Spaghetti squashes are also highly nutritious, and they’re one of the best gourds to grow for your garden if you love healthy foods!

If it’s your first time growing these beauties, you might not know what to look for in healthy plant development – and most importantly, when to harvest

Here are some top tips on how to grow, harvest, and cure spaghetti squash, so that you can enjoy these tasty veggies throughout the winter.

How to Plant Spaghetti Squash

Some of our gardening friends live in cold climates with short growing seasons! If that’s the case – germinate your spaghetti squash indoors around 2-3 weeks before the final frost. We recommend these peat-pots-az/” linkid=”15591″ data-lasso-id=”13443″>peat pots – they’re easy and cheap!

Squash needs warm soil (25°C/80°F) to germinate, so most gardeners wait until late spring to sow their seeds outdoors. Luckily, these vigorous growers only take seven to fourteen days to sprout.

If starting indoors, sow your spaghetti squash seeds in May. A word to the wise, though! It’s important not to start squash too early. They will rapidly outgrow their pots and need transplanting into larger spaces quicker than you think. 

Like most gardeners, I always seem to be short on time, so I always opt to directly sow my squash in June so that I don’t have to worry about potting up my transplants.

Squash are large vining plants that will happily tumble out of raised beds and explore your garden pathways – they love to stretch! 

At a minimum, you want to plan on giving each plant a three-foot radius. Squash love locations with full sun and can be encouraged to climb trellises, making them a tremendously beautiful addition to your garden.

Our Pick
100% Biodegradable Peat Pots 3-Inch Cups

Spaghetti squash demands a long growing season! That's why many gardeners swear by handy peat pots.

Peat pots are excellent for germinating your spaghetti squash indoors while the weather is too chilly outside, and you risk overnight frost.

Peat pots can also help germinate other gourds and veggies too! These peat pots are perfect for nurturing all kinds of baby sprouting seedlings, including cucumbers, zucchinis, pumpkins, peas, and more!

How to Grow Spaghetti Squash

As you look at this young spaghetti squash – notice how the color is still pale. There’s no deep yellow tone! I would wait for this spaghetti squash to mature before harvesting.

Feed, feed, feed! Squash has a reputation for growing on tops of compost piles – for a good reason. They are hungry plants that need lots of nutrition to grow. Before you plant, top-up beds with high-quality compost

During the growing season, you can apply a liquid compost or granular fertilizer to boost growth.

When choosing a fertilizer, opt for one with higher phosphorus levels. Phosphorus encourages flower and fruit production. If you use a fertilizer high in nitrogen, you may find lots of leaf production – but fewer squashes!

Squash plants will produce male and female flowers. The female flowers are particularly distinctive because they have a swollen base, where the squash will form if pollination is successful.

But, pollination takes luck – for a flower to pollinate, as many as twelve visits from pollinators are required!

As you can imagine, proper pollination does not always occur. If you find a shortage of bees in your garden, you can hand pollinate your squash! Start by using a paintbrush to transfer pollen from the male flower over to the female flower. 

You can also attract more bees to your garden by planting bee-friendly flowers like borage, calendula, and marigolds.

Watering Spaghetti Squash

Consistent watering is vital – your spaghetti squash gets thirsty! Doubly so if you live in a hot, arid climate.

Depending on whether the plants are tiny seedlings or if they’ve sprawled wildly across your yard, they will need anywhere between one to two inches of water per week

Adding straw around the base of the plant will prevent evaporation and can stop the vegetables from resting directly on the soil. Getting your veggies some straw padding as breathing room can prevent fruits from rotting before they reach maturity!

Like all members of the squash family, these plants are susceptible to powdery mildew. Be proactive and avoid getting the leaves wet when watering. Do your best to always apply water at the base of the plant, directly onto the soil.

How to Harvest Spaghetti Squash

Notice the flesh of these spaghetti squash specimens is beginning to darken! As the skin turns darker shades of yellow, you know it’s time to assess the thickness of the skin. If it feels hard – it’s ready to harvest!

It takes squashes around 90 – 110 days to reach maturity, so be prepared to wait until early fall. If you live in a cold climate, pick your squashes before the frost comes.

You will know your squash is ready to harvest when the skin is a deep yellow. Also – remember that squash skin hardens as it matures! So, you want squash skin tough enough so you can’t easily puncture it with a fingernail.

One more thing. Look at the vine! There are good odds that by the time the squash is ready to harvest, the vine will have died back as well.

To harvest, use sharp pruning shears to cut the stem about three inches from the squash. The vines get prickly sometimes, so I recommend gardening gloves when handling them!

Our Pick
Black Kow Composted Cow Manure 4 lb. Size

I prefer natural fertilizers - like compost and manure. I feel like cow manure is ideal for vegetable gardens - spaghetti squash and other winter squashes included.

I love Black Kow cow manure because their cow manure is organic! And, they also have excellent reviews.

A 4-pound bag of cow manure is perfect for tilling and working into your small raised garden bed to help refresh the soil and give it a boost!

How to Cure Winter Squash

spaghetti squash curing indoors
Curing usually takes 10 to 14 days – and air circulation is vital! You can let your spaghetti squash cure on your dry cupboard or countertop. Or, tuck your squashes away on a well-circulated drying rack.

Spaghetti squash is also a winter squash. Interestingly, winter squash does not get their name from the season they are grown, but rather after curing, they should (hopefully) last throughout the entire winter. (Hence, winter squash!)

To cure your squash, all you need to do is set your squash in a warm, well-ventilated space for ten to fourteen days. If the weather is warm and dry, this process can work outdoors. 

If the weather is less desirable, bring them into a warm area of your house. I believe in your ability to incorporate spaghetti squash into your fall décor scheme for fourteen days. Have fun and use your imagination!

Airflow is important. If possible, you want air to be able to access all sides of the squash.

For this reason, I like to put my squash inside vented plastic produce boxes. Milk crates also work great for this. If you don’t have a vented container like this at home, you can turn your spaghetti squash every couple of days. 

After you cure your squash, move them to a cool and dry spot in your home for storage. A well-cured squash can last up to six months

When to Pick Spaghetti Squash? My Final Tip!

My final spaghetti squash harvesting tip is to remember not to wait too long to harvest!

Sometimes, if you wait too long – your spaghetti squash will get too big, too thick, and then the skin gets way too hard! I’ve also noticed that gourds get too many seeds as they get too large.

So, remember that size isn’t everything! Pay attention to the deep colors of your spaghetti squash – and harvest when the skin begins to harden.

After a while, you’ll develop a harvesting schedule that you like the most. Some gardeners harvest their spaghetti squash slightly earlier than others – some later. Find your best preference, and then happily harvest your crops at your pleasure!

Either way – the vigorous growth of these vines, coupled with their ease of harvesting, makes spaghetti squash a satisfying addition to any backyard garden!

Plus, if you’re anything like me, once you taste your first spaghetti squash lasagna, you’ll salivate at the thought of growing these delicious beauties over and over again!

If you haven’t already, I strongly recommend that you give spaghetti squash a try!

Something ate part of one of my spaghetti squash, it’s still green, cam I cut the chewed part off & use the rest?


Tuesday 30th of August 2022

Hi there Carol! Personally, I use everything from my own garden, whether it's chewed or not. I just cut the damaged part off and use the rest. However, you'll need to be careful with diseases, depending on which animal chewed your squash. I have never worried about this, but I found some information that suggests there may be reason to worry:

Vegetables damage by wildlife: Several foodborne illness outbreaks attributed to produce were thought to be caused by wildlife. More specifically, the poop they leave in the vicinity. If something has nibbled at your lettuce, look around for signs of rabbit pellets or deer poop. If your tomatoes are covered in bird waste, leave it be. Don’t harvest any fruits or vegetables that appear to be contaminated by animal wastes: E. coli O157:H7 and Salmonella are two of the bacteria that could be found in them.

This refers mainly to animal waste, but I'm mentioning it in case it refers to bites/saliva also. They also mention that insect damage is fine:

Insect damage, healed cuts, small holes or scars: For the most part, insect damage does not render fruits and vegetables inedible. If slugs take a little chew out of your lettuce or a weevil leaves a small hole in your pepper, cut away the damage and thoroughly inspect what is left. If it all looks good, then feel free to eat the rest.

I'm generally more worried about the chemicals they spray commercial vegetables with than any animal matter that may occur in my garden. But it never hurts to be cautious!
