Living in Tulsa, OK, for 11 years, I asked the locals if crime was a problem. They replied, “Well, in August you better be sure to lock your car, because otherwise someone might put a bag of zucchini in your car.” People who grow zucchini, like me, harvest more than we can eat.

Zucchini, a summer squash, is a member of the gourd family. It originated from Central America from where it has spread to the rest of the world.

This popular succulent vegetable does well in warm weather, in places with moist, fertile soil. It takes 35 to 60 days from planting to first harvest. The plant grows to a height of two and a half feet. For best flavor, zucchini fruits are harvested when they are 4-8 inches.

Darker fruits are usually higher in nutrients. But what are the nutritional benefits of zucchini?

Editor’s Note: Botanically, zucchini is a fruit, but it’s most often used like a vegetable.

What Are The Nutritional Benefits of Zucchini?

Zucchini contains zero fat, and is high in water and fiber. It also contains significant amounts of vitamins B6, riboflavin, folate, C, and K, and minerals, like potassium and manganese.

The summer squash also contains antioxidant and anti-inflammatory phytonutrients. This makes zucchini, also known as courgette, a nutrient-dense food that you should include in your diet.

Zucchini Benefits: 9 Reasons to Eat More of This Squash

1. Improves digestion

Incorporating zucchini in your diet can help improve digestion including reducing the incidence of constipation and other digestive issues.

Zucchini is high in water. It also contains significant amounts of fiber, electrolytes, and other nutrients that are necessary for a healthy digestive system.

Regular consumption of zucchini can also help prevent ulcers, IBS, and colon cancer.

2. Slows down aging

Aging results from the activity of toxins, free radicals, and inflammation that the body is exposed to over the years. These poisons and inflammation can be reduced by antioxidants and anti-inflammatory foods.

Zucchini is rich in antioxidants and anti-inflammatory phytonutrients, which help rid the body of free radicals and excess inflammation.

3. Lowers blood sugar levels

High blood sugar levels and diabetes are problems that are worsened by a diet high in (unhealthy) carbohydrates and low in fiber.

By including zucchini in your diet, you increase the intake of fiber. You can also reduce your carbohydrate intake because you will feel full for longer. These diet changes can help reduce your blood sugar levels and increase insulin sensitivity.

This can mean that your body no longer requires excessive amounts of insulin to process sugar. This can change your risk of developing diabetes. Studies show that including at least 30 grams of fiber in your daily diet lowers your risk of getting diabetes significantly.

4. Supports healthy circulation and a healthy heart

Zucchini is low in fat and sodium, but high in fiber and potassium. These properties help to maintain healthy blood circulation.

Low sodium and high potassium help to maintain healthy blood pressure while fiber, such as the polysaccharide in zucchini, lowers cholesterol levels.

This combination works synergistically to maintain good circulation, which is necessary for healthy blood pressure and a healthy heart.

5. Improves eye health

Zucchini is a good source of health-protecting antioxidants and phytonutrients, including vitamin C, beta-carotene, manganese, zeaxanthin, and lutein.

Zeaxanthin and lutein are especially useful in maintaining and improving eye health by fighting free radicals. This reduces the risk of developing age-related eye conditions like glaucoma, cataracts, and macular degeneration.

You can also use zucchini to treat puffy eyes by placing slices of raw zucchini over the eyes. Leave the slices in place for about 30 minutes and repeat several times in a day.

6. Boosts energy

Because zucchini is a rich source of B-vitamins, especially folate, riboflavin, and B6, it can help to boost energy production in the body. This reduces fatigue and improves moods.

The body requires B-vitamins for protein and carbohydrate metabolism. These vitamins also aid in various brain functions including cognition.

7. Weight loss

Because zucchini is low in calories and high in water and fiber, it is a great food for those wishing to reduce their body weight.

It is worth noting that excess body weight usually results from regular consumption of carbohydrate and sugary foods.

By including zucchini in your diet, you increase the fiber and water content of your food. This means that you will feel full for longer and end up eating less. In the long term, you will lose some of your excess weight.

8. Improves thyroid and adrenal functions

Zucchini contains high amounts of vitamin C and polyphenols, especially in the peels.

Laboratory studies on rats by the Devi University found that the compounds in zucchini peels have positive effects on the thyroid and adrenal glands. Additionally, the compounds helped in the regulating insulin levels.

9. Protects against oxidation and inflammation

Zucchini is rich in antioxidants and anti-inflammatory compounds, including vitamins A and C, glutathione peroxidase, and superoxide dismutase. Large amounts of these compounds are found in zucchini skin. For this reason, you should eat the skin together with the flesh.

Eating zucchini regularly reduces oxidation and inflammation within the body. This boosts your immunity and protects against diseases associated with inflammation.

All these zucchini benefits are impressive, so aim to add more to your meals, and if you can, try growing your own.

How to Grow Zucchini In Your Backyard

Zucchini grows best during the warmer months, which is why it’s also called summer squash. However, you can still grow it at other times provided it is shielded from extreme cold.

If you get your system down, zucchini plants can become extremely productive with fruits.

If you would like to grow zucchini in your backyard, here is what you need to do:

  1. Prepare the growing area by digging to loosen the soil.
  2. Add organic fertilizer and mix well into the soil
  3. Create mounds of about 2-feet diameter, up to 10 inches high and about four feet apart.
  4. Plant six seeds per mound, spacing them evenly. Cover each seed with soil no deeper than one inch and water them thoroughly.
  5. Thereafter, water your zucchini seeds once or twice a week depending on the weather.
  6. Once the seedlings emerge, wait until the healthiest are about three inches tall. Weed out the weaker ones, leaving two or three in each mound.
  7. Continue watering as needed, aiming to get the water near the roots.
  8. When your zucchini start flowering, you may need to add fertilizer to support growth of the fruits. Also water more often, especially if the weather is hot.
  9. Zucchini takes about 60 days from planting to harvesting. Harvest zucchini as you need them when they are about six inches long. Fruits taste best at this stage. If you let them to grow for too long, they start getting woody and won’t taste too good.
  10. Enjoy your home grown zucchini raw or cooked.

Editor’s Note: Several types of genetically engineered zucchini have been approved for sale in the U.S. and in Canada, so if you want to avoid GMOs, we recommend choosing organic zucchini.

You can enjoy zucchini many ways, including the popular zucchini noodles (zoodles) — a pasta alternative. For a different idea, try these Zucchini Bars for a healthy breakfast or snack.

Pruning Zucchini: How To Prune Zucchini Squash

Zucchini squash is easy to grow but its large leaves can quickly take up space in the garden and prevent fruits from receiving adequate sunlight. Although it’s not required, pruning zucchini can help alleviate any overcrowding or shading issues.

In addition, pruning can help stimulate additional zucchini growth. If you are asking how or when do I cut off zucchini leaves, this article will provide the information you need. Let’s look at how to prune zucchini squash.

How Pruning Helps Growing Zucchini Squash

Zucchini plants are prolific producers when given the right care. Although zucchini can grow in nearly any soil type, it does rely on well-drained soil along with plenty of sunlight to produce adequate fruit.

Zucchini plant leaves grow so large that they can often shade the plant itself and reduce sunlight to itself or surrounding plants. This is why cutting leaves to give zucchini more sunlight may be required. In addition, pruning zucchini allows more energy to reach the fruits rather than the majority of zucchini plant leaves.

Pruning zucchini plant leaves can also improve air circulation and help to prevent the powdery mildew that zucchini is susceptible to.

When Do I Cut Off Zucchini Leaves?

Once zucchini plants have begun to set fruit, between four and six fruits on vine, you can begin pruning zucchini. Start by nipping out the tips and continue pruning plants as needed throughout the growing season. Be careful not to prune too close to the developing fruits.

How to Prune Zucchini Squash

When pruning zucchini plant leaves, take care not to remove all the leaves. Keep some leaves on the stem, including leaf nodes near the last fruit you want to keep. When cutting leaves to give zucchini more sun, just cut the bigger ones, and make the cuts close to the base of the plant, leaving all others.

You can also cut off any dead or brown leaves that may be present. Do not cut any stems, as this will increase the risk for disease.

Proper Zucchini Plant Pruning

Reasons for Pruning

Zucchini pruning chores can be as simple as tearing off part of an insect egg infestation or as drastic as cutting off several stems and leaves. A heavily pruned zucchini plant loses much of its original beauty, but gains other rewarding benefits. Important reasons for pruning zucchini plants are:

  • Removal of insect eggs
  • Removal of diseased leaves or stems
  • Improving air flow to plants
  • Giving other plants room to grow

How to Prune

Pruning diseased or insect-infested leaves and stems seem like a wise task to perform, but pruning healthy zucchini parts can cause a bit of new gardener anxiety. Experienced zucchini growers know that proper pruning will benefit the plant in many ways.

Pruning should not begin until after four to six zucchini fruits have grown on the plant. Each plant will have unique pruning needs. Evaluate the needs and prune by following these guidelines:

  • Diseased, dead, or insect-chewed leaves should be removed.
  • Using a sharp knife or shears, cut off entire stalks that appear dead or damaged. One inch or more of the cut stalk should remain at the base of the plant.
  • The largest and outermost leaves should be cut off only when there is no squash growing directly beneath the leaves.
  • Low-growing stalks and leaves should be removed. This will help improve air circulation around the plant.
  • After removing diseased, insect-infested, and low-growing plant parts, evaluate the plant. Cut off any stalks and leaves that are invading another plant’s space.
  • When pruning, cut off only stalks that have no fruit growing on them.

Precautions when Pruning

Removing any zucchini plant part, including the fruit, should only be done with a sharp implement such as a knife or shears. Using dull tools for pruning may injure the plant. Twisting the stalks or leaves off may do even greater damage. Disinfect pruning tools between use to prevent diseases from entering freshly cut plant parts.

Determining how many leaves and flowers to prune from a zucchini plant may be the most difficult part of pruning. If too many plant parts are removed, the vitality of the plant will be reduced. Removing too many leaves may hinder the photosynthesis process. Removing too many flowers will hinder fruit set.

How to Prune Zucchini

Zucchini is one of the easier vegetables for the home gardener to grow. The plants can grow in almost any soil with proper drainage. While zucchini is easy to grow, it does take maintenance to get the most out of your plants. Pruning your zucchini plant is an easy task if you know what to do and when to do it.

Wait for the plant to set fruit. Look for your zucchini plant to have five or six actual zucchinis on it before pruning. This shows that the plant has reached maturity and can sustain itself without help. Keep an eye out for browning at this stage, as this may warrant pruning leaves early.

Nip tips off with garden scissors to conserve energy for growing fruit. Look for multiple tips or new growth along the stems near each other, and nip off any new tips near growing fruit. This will allow the zucchini you already have to grow larger and faster because the plant will have fewer directions to send nutrients and resources.

Trim the large leaves from the plant as they become too large for sun to reach the growing zucchini. Don’t cut all the leaves–just the ones that have become too large to be of use. Watch the plant and prune away old growth for the duration of the growing season.

Pick zucchini as it matures to redirect the plant energy to newer growth. Grab the end of the fruit and twist until it snaps off the vine. As you prune your plants, you will notice more tips growing farther up the vine. Continue pruning tips which lie close together to allow new fruit to set faster. When the zucchini ripens, picking the mature fruit which will allow new fruit to set all along the vine.

Avoid cutting the stems. Like cucumbers and peas, zucchini produce multiple root stems which will produce their own fruit. Keep as many of the stems as possible to gain the most production. Direct the stems from each plant along the same general path by placing them along side each other as they grow so that pruning one plant takes less movement and is more organized. This also helps keep any potential mildew or disease from spreading should it occur.

Faith Willinger

To try Faith’s recipe for a carpaccio of thinly sliced zucchini with olive oil and herbs, click here.

The first zucchini of the season—tender, tiny—and a bag of zucchini flowers from my favorite farmers, the Innocenti brothers, are celebrated in my kitchen. In Italian zucchini is female (zucchina, singular, zucchine, plural), a vegetable that’s the result of the small but functional female flower’s fertilization by the big flashy, stemmed male flower (il fiore, masculine).

After the act, males are unproductive, fried in batter by most Italian cooks. Not me. I stuff male flowers with ricotta—place ricotta in a pastry bag, insert into flower, and squeeze (neatness doesn’t count), put stuffed flowers in a layer in a non-stick pan, drizzle with a little extra virgin olive oil, cover and cook over medium heat for five minutes. The moisture from the ricotta will steam the flowers. Chopped male or female flowers, sautéed in extra virgin with garlic, make a fantastic sauce for pasta or can flavor risotto. Italian farmers sell the female vegetable with its flower attached, clearly not practical for supermarket sales, since female flowers wilt and die rather quickly.

I make zucchini carpaccio, slicing the vegetable into thin rounds with a ceramic blade mandoline straight onto the platter, and use a potato peeler to slice strips of Parmigiano or Pecorino on top. I season the slices with salt and pepper, then drizzle them with extra virgin and garnish with chopped female flowers and the season’s first basil. See recipe below.

Eat Shoots and Leaves

I recently learned that there is more to squash than just the squash; the young shoots are not only edible, but a delicious green!

Squash shoot aglio e olio

Fellow cucurbitacean Amy Goldman introduced me to them in her book, “The Compleat Squash.” I had heard of eating pea shoots before… but squash?! I had to find out if these are worth the effort.

They are.

In my growing zone (6b), it’s been a little early to sow squash seeds yet. And with my limited growing space, I’d be reluctant to start snipping my prized plants for an experimental side dish, anyway.

Then, in early March, inspiration struck from the inside of a Thelma Sanders Sweet Potato winter squash: I found little sprouts inside the squash’s seed cavity. This phenomenon, called vivipary, is frequently caused by declining levels of abscicic acid (ABA) in plant seeds, a plant hormone that prevents germination. I had harvested the squash in September, so it was no big surprise that ABA levels would be low enough to cause seed germination (storage at cold temperatures, like your refrigerator, accelerate ABA loss, by the way… another reason to store squash in cool, not cold, temperatures).

Word of the day: vivipary.

But honestly, until I saw these little seedlings in my squash, I hadn’t considered using the seeds for anything other than roasting. After all, I’ve never taken the necessary steps to prevent cross-pollination between the many squash varieties I grow each year, so I never use them for seed-saving (as they wouldn’t be true to type). Now I’ve found a fabulous new use for them, and a great way to grow greens indoors in winter.

I took the remaining seeds from the squash cavity, placed them in the refrigerator for 2 weeks (just to accelerate additional loss of ABA from the seeds and insure germination), and planted them in a flat filled with organic potting soil. I was already starting tomato, eggplant, and pepper seeds under lights anyway, so here was the perfect opportunity to try squash shoots, at no cost to my seed inventory or future squash yields.

About one month later, I harvested the young shoots, which had grown great in the flat despite crowded spacing and a shallow planting depth (I was growing them just for shoots, after all… don’t try this with plants you’d like to set in the garden).

Mmmm… squash shoots.

I prepared the shoots as I do broccoli raab or swiss chard; braising first in a small amount of water, then sautéing in olive oil with fresh garlic, black pepper, and sea salt.

The only downside to squash shoots? An entire flat of shoots, which when harvested was enough to fill a 1 gallon bag, made enough for a side dish for one family dinner (with guest). Like kale, a lot of greens goes a little way when cooked.

All the same, I will be making this dish again. My daughters enjoyed planting the seeds and watching them grow (which if you’ve grown squash, you know happens FAST), and it is a beautiful and novel side dish to boot.

Squash Shoot Aglio e Olio Author: Ma Hubbard Ingredients

  • Young, fresh squash shoots (any variety of summer or winter squash)
  • Water
  • Extra Virgin Olive Oil
  • Black peppercorns
  • Sea Salt


  1. In a large skillet on medium-high heat, add squash shoots and water to just cover the bottom of the pan. Cover with a tight-fitting lid and cook shoots for 1-2 minutes.
  2. Remove lid. Allow any remaining water to evaporate from skillet. Add olive oil to preference (I add about 1-2 Tbsp olive oil/gallon bag of greens) and sauté greens with freshly-ground black pepper and sea salt.
  3. Serve warm.


It’s Zucchini Season! How You’ve Been Growing Them All Wrong.

You probably think you already know how to grow a zucchini but if you live in North America … you might not. Here’s the way to grow zucchini to make your plants last longer, take up less space and produce more.

Why would you want your zucchini plants to produce more, you’re asking? Because of the obvious. They’re fun to throw through people’s open car windows during zucchini season.

Zucchini are one of those vegetables that already produce more than you ever expect them to and seem relatively easy to grow. And they are. But you can do a MUCH better job of growing them if you’re aware of these 3 surprising things about zucchini plants.

Most surprising of all is the fact that Zucchini can perform complex math equations.

No they can’t.

Growing Zucchini

Zucchini need to be pruned and staked. For real. Like a tomato.

Zucchini can be planted VERY close together. 1 per square foot.

Powdery Mildew CAN be halted. O.K., maybe not entirely halted but slowed wayyyyy down.

Pruning and Staking Zucchini

The only other plant in my garden that I prune more than my zucchini are my tomato plants. Just like tomatoes, zucchini benefit hugely from pruning. They’ll be susceptible to less disease, have a more open formation that allows easier access for bees to pollinate and they’ll take up less space.


It’s best to stake your zucchini when you first plant it, but you can still do it during the growing season.

Plant a stake right next to the main stem of the zucchini plant. You may not have noticed it before, but zucchini all come from one stem. That stem is just usually sprawled and dirty on the ground covered in decaying leaves. So you can’t get a good look at it.

But trust me. Zucchini have one stem, that can be staked just like a tomato.

The earlier you do it the easier it is though.

Above you can see a zucchini plant that’s only been staked and tied once, earlier in the season with the rest of the growth just flopped over. The leaves are being eaten by bugs, there’s no air circulation and the lower leaves near the soil are getting powdery mildew.

Here’s the same zucchini plant after staking it properly and removing all the lower leaves.



Zucchini leaf stems are hollow UNTIL they get to the stem of the plant. There they turn solid again. Prune your zucchini leaves right up to the stem of the plant so you don’t have any of the hollow stem left.

Hollow stem portions car harbour disease and bugs so make sure you get right close to the plant stem when removing the leaves.

See the difference from the left photograph and the right one?


The developing zucchini gain all their energy from ONLY the leaves growing above them. The leaves below, are just taking energy away from the rest of the plant.

Pruning away diseased and damaged leaves helps prevent and slow powdery mildew by creating greater air circulation.

Pruning away the larger, lower leaves that aren’t contributing to the plant means you can plant more zucchini in a smaller space.

Spacing Zucchini

Most guides tell you to place zucchini plants at least 24″ apart. You don’t need that much room between them.

Plant zucchini 1′ apart in 1.5″ rows.

If you’re staking them and pruning them this is all the room they need.

Here you can see pre-pruning and staking …

And below you can see post pruning and staking.

Powdery Mildew on Zucchini

It’s the kiss of death, but luckily it’s a long, slow, torturous death. Most zucchini plants seem to be able to withstand powdery mildew for quite a long time.

But to make your zucchini plants last into the late summer and early fall, you can take a few steps to slow down powdery mildew.

If you’re growing zucchini plants by staking them and pruning them, you’re already doing a LOT to keep powdery mildew at bay. But for extra protection you can spray your Zucchini with a mixture of vinegar and water. I have a full post on how to make and use the spray on zucchini here.

For some reason in North America gardeners don’t use these techniques for zucchini (pruning and staking). But in Europe it’s been the way to do it for centuries. I made that centuries part up, but I imagine it’s probably true.

Zucchini may not be able to do complex mathematical equations but they can add up like nobody’s business.
