When to Pick Zucchini

The ideal time to pick a zucchini squash is when it reaches six to eight inches in length, with bright green skin tinged with a slight yellow hue. Some cultivars have fruit that is still edible at up to a foot.

Zucchini squash is known for its fast growth. A zucchini, left unchecked, can grow into a gigantic squash in only a few days.

(Never wait until tomorrow to harvest your zucchini. If it looks around six to eight inches? And if the skin is still tender? Harvest it now!)

Picking the perfect zucchini is an art form and not one to be taken lightly. After all, who wants a sub-par vegetable? So – we also want to share more zucchini harvesting tips with you.

Here goes!

Knowing when to pick zucchini is easy. Harvest your zucchini when it’s still immature – and around five to eight inches long. Young zucchini gourds have delicious and tender skin. Zucchini skin gets too hard if you wait too long to harvest. And there isn’t as much of a sweet flavor! We also find that mature fruit zucchinis have large and chewy seeds.

5 Signs That Your Zucchini Is Ready to Pick

Knowing when to harvest zucchini gourds is just as important as growing them properly. To master the art of harvesting zucchini, pay attention to these telltale signs that they’re ready to pluck.

1. Your Zucchini Plants Are the Right Size

Here’s the best indicator of when to pick zucchini. The zucchini’s size! Zucchini fruits are typically six to eight inches long when they are ready to be harvested, and some zucchini squash plants can grow even bigger while still being ripe. The size of the zucchini fruit is a vital indicator of ripeness.

2. The Zucchini Looks Dense and Heavy

One way to tell if a zucchini plant is ripe is by picking it up. A ripe zucchini will feel dense and heavy for its size. The high zucchini density is due to the water content of the fruit. It will also feel firm when you squeeze it.

3. The Zucchini Skin Still Feels Delicate

The skin of your zucchini gourd is also an excellent indicator of whether it’s ready for harvest – or past due. Zucchini readying for harvest should still have delicate skin. When zucchini fruits are young, their skin is tender and can easily scratch away.

If the skin is too hard, you’ve waited too long! But – we still advise harvesting mature zucchini so the plant may replenish itself with fresh young gourds.

In the late summer, with warm weather, your zucchini plants need lots of water! Most reliable sources we study say healthy green zucchini plants need around one to two inches of water weekly. However, in the summer, we usually give our zucchini plants more. (We water our entire vegetable garden a few times per week. Usually about an inch or two per watering session. The plants don’t mind – doubly so when the hot sun beats down on their leafy greens!)

4. The Zucchini Skin Has a Rich Green and Yellow Hue

The majority of zucchini plants will be a rich, dark green color when they get picked. However, other varieties will be light green or yellow. Pay attention to the color of the zucchini fruit to determine if it is ready to be harvested. If unsure, look at pictures of ripe zucchini for the specific summer squash you’re using.

5. It’s at Least 50 Days After the First Sprouting

Keep track of the days after you planted your zucchini seeds. Most zucchini varieties will be ready to harvest as soon as 50 days after planting. This time-to-harvest ranges from 45-60 days, depending on the specific type of summer squash. Use this as a general guideline while checking on your zucchini plants regularly.

Why Is My Zucchini Bitter?

You may every so often come across a bitter zucchini. Cucurbitacins, a class of compounds found in plants such as summer squash, zucchini, and gourds, are responsible for the bitterness of these vegetables. Environmental stress can increase cucurbitacin levels, making your zucchini mildly bitter. (Wide temperature variance or inconsistent watering may contribute to environmental stress.)

How Big, Is Too Big?

It’s easy for there to be hidden fruit on your squash vine, and it’s common to miss one now and then. However, if you let a zucchini grow too big, it will become overripe, seedy, and bitter. Not to mention, it will be tricky to cook or integrate into any halfway-tasty recipes.

If you produce fruit over 12 inches long, it may be best to compost it.

Feel free to give it a taste first to make sure it’s not worth consuming, but generally, the larger the zucchini, the more mealy it tastes.

A zucchini left on the vine for too long will also start to wilt and collapse. If you see any fruit on your plant that looks past its prime, harvest it as soon as possible.

Zucchini grows best in a sunny spot in your garden with well-draining soil. Zucchini plants are not frost-tolerant. So you must wait for the last killing frost of the season to pass before transplanting. Harvest your zucchini when the skin is still easy enough to puncture with a fingernail. And harvest your zucchini gourds regularly! That way, your zucchini plant will readily produce more fresh gourds.

Do Zucchini Ripen After Picking?

Yes, you can ripen a zucchini plant off the vine. The best way to do this is by harvesting zucchini plants and then letting them sit in an open container for a day or two in direct sunlight. It will start to get softer and sweeter as it ripens.

You can then store zucchini in the fridge for up to two weeks. But keep in mind that the longer you keep zucchini and wait to eat it, the more likely it is to develop brown spots and become mushy.

How Big Should Zucchini Be When I Harvest Them? What’s the Ideal Size?

The sweet spot for picking zucchini is when they’re around six to eight inches long. That’s when they’re the most tender and have the best flavor. A full-sized unpicked zucchini can grow up to two feet! Pick the fruit regularly if you want to keep your zucchini plant productive.

What Happens When You Pick the Zucchini Flowers

If too many flowers get picked off of your zucchini plant, it will lead to low pollination levels. Female and male zucchini flowers grow on the same plant, but only the female flowers turn into fruit.

The male flowers grow on a long stem and have a thinner base, while the female flowers are shorter with a bulbous base. If unsure when identifying a zucchini flower or determining the sex, look for the tiny zucchini at the female flower base.

It’s best to leave some of each type of flower on the plant to ensure proper pollination and a good zucchini harvest. But feel free to pick a few, as they are an edible delicacy.

Do Zucchinis Plants Continue Growing If the Flower Falls Off?

After the male flowers open up and release pollen, they eventually fall off the plant. The female flowers will also fall off if they remain unpollinated.

Usually, waiting for the female flowers to open is all that is needed for new summer squash fruits to form. But if these flowers don’t open for one reason or another, you may need to pollinate them manually.

Check out the mature color of various zucchini cultivars. They always keep us guessing! Some cultivars have orange, green, yellow, or striped designs. Some zucchini are so dark that they look black. We also read a fascinating insight saying the Eastern US market prefers light green zucchini while Western US gardeners prefer a darker shade. The color doesn’t concern us much – green, yellow, orange. We think they’re all delicious!

How to Harvest Zucchini

Consistently check on and keep harvesting zucchini plants to ensure a higher yield. A more consistent harvest will lead to a continuous harvesting cycle.

When harvesting zucchini gourds, do not twist the fruit from the plant. Damaging the plant is probable if you act in this manner. Carefully cut the fruit from the plant, ensuring it includes as much of the stem as possible.

Thoroughly scan your garden beds for any zucchini ready to be harvested. The large leaves produced by the zucchini plant can hide mature zucchini waiting for harvest if you don’t look closely enough.

Finally, make sure to store zucchini correctly once harvested. Keeping zucchini is simple, and you have a few different options. You can refrigerate them, freeze them, or pickle them.

If you want your zucchini to last a little longer, refrigerate them in an airtight container after cutting off the stem. Zucchini can get stored in the freezer, which is an excellent option if you have a massive zucchini or too many to eat. You can dice or shred your squash and place it in airtight freezer bags. Frozen zucchini lasts around eight months.

How Often to Harvest Your Zucchini Plant

Most reliable sources advise harvesting zucchini as often as possible so that the plant continues to produce fruit. Once you start seeing fruit on your plant, check it daily and harvest any that are big enough to eat.

If you want to get a little more technical with your zucchini harvesting procedures, you can keep track of the days, starting when you first see flowers on your zucchini plant. Once 50 days have passed, most of the fruit should be mature and ready to harvest.

Ideally, you check your zucchini plant every other day or every three days. That way, you will ensure a continuous supply of fruit and prevent the squash from getting too big.

Our editor from New England loves zucchini. They grow two zucchini harvests every summer. They start the first zucchini garden in early June. Then, in late July, they transplant a second batch. Mature zucchini only take around 30 to 50 days to mature. So, if you plan your planting, you can have a continuous harvest all summer. Yummy and fresh zucchini for everyone!

How Do I Harvest and Cut Zucchini Fruits When They’re Ready to Pick?

Be careful with the vine! Use clean garden shears to cut the zucchini when harvesting. Aim as close to the base of the plant as possible.

(We admit that sometimes we twist the zucchini when harvesting, but that’s not the best option. Not by a long shot.)

What’s the Best Time of Day to Harvest Zucchinis?

Any time of the day is good for harvesting zucchini. On surprisingly hot days, your plant may be expending a lot of energy, so don’t harvest zucchini at midday in severe heat. Give your plant a little love and water after pruning and harvesting so that your plant gets back to work and keeps growing.

How to Pick Zucchini Flowers

Make sure you only pick the male flowers if you want to eat them. The female flowers are the ones that will turn into zucchini squash. Don’t harvest those!

To pick zucchini flowers, hold on to the stem and twist the zucchini flower off of it. If you have a hard time doing this, use a sharp knife to cut the flower off cleanly.

If you grow zucchini, squash, or pumpkins, you must watch out for these tiny red eggs. They belong to the sworn enemy of zucchini blossoms everywhere. Squash bugs! The best way to get rid of these nasty critters is to scan your leafy greens daily. Check the underside of the leaves for the red eggs. Remove infected leaves and toss them into a jug of water diluted with a small dash of natural dish soap. Scan your zucchini leaves daily. (Squash bugs infect your zucchini leaves with toxic saliva that quickly damages the plant! It’s worth your time to scan and remove them.)

Zucchini Harvest Problems and FAQs

As with all plants, problems may arise during the zucchini harvest. Here are some answers to the most common zucchini harvesting questions.

Should I Harvest Zucchini Gourds Before an Overnight Frost?

Zucchinis are very sensitive to frost and usually don’t survive through the season’s first frost. If a light frost is forecasted, you can try to protect your plants with sheets or tarps. If a hard frost looms, it’s best to harvest your zucchini. Don’t let them go to waste!

My Zucchini Flowers Are Falling Off the Plant! And It’s Not Producing Zucchini Gourds!

Male flowers usually die after shedding pollen. But your defoliating zucchini plant may be happening because the female flowers are falling off before they can get pollinated. Your squash plant requires male and female flowers to reproduce and make fruit. So, if you only see male zucchini flowers, you won’t get any squash. If female zucchini flowers keep dying without getting pollinated, you may need more bees.

Increasing pollinators such as bees in your garden may help solve this problem. You can also try hand-pollinating the flowers by transferring pollen from the male to the female flowers if you can identify them.

Why Is the Zucchini Turning Yellow and Fading Before I Can Pick It?

Your plant may have blossom end rot if it has a waning texture and yellow color. Blossom end rot can happen if there is a marked fluctuation in moisture levels. In other words – inconsistent watering. So make sure to keep an eye on the watering of your plant.

Didn’t water your plant enough? The lack of moisture may have caused your zucchini to wilt and die. If you catch the problem early enough, you can try reviving your plant by giving it a good watering. (But blossom end rot is very hard to fix sometimes. For that reason – water your zucchini plants routinely. And regularly!)

Too much water can also lead to blossom end rot, so ensure that your plant gets the appropriate amount and gets planted in well-drained soil. If you think over-flushing may be the problem, stop watering your plant for a few days to let the soil dry out.

The Leaves Look White and Powdery! Is the Fruit Still Safe to Eat?

This texture is likely powdery mildew. Powdery mildew is, unfortunately, pretty common in squash plants. The good news is that the fruit is still edible, but you should wash it before eating to eliminate any residual powder. You can also peel your zucchini to remove all of the powder.

To prevent powdery mildew from returning, try to increase air circulation around your plant by thinning the leaves. You can also try spraying the leaves with a fungicide if the problem persists.

Once you harvest your zucchini, you have tons of delicious opportunities! Zucchini is perfect for pickling and storing long-term. Zucchini also tastes delectable when chopped in Asian or classic American dishes. And there’s no such thing as leftover zucchini! You can use zucchini to make to-die-for zucchini breadchocolate bars, or roasted zucchini vegetable sandwiches. The goodies never end!

Conclusion

Knowing when to harvest zucchini is easy. Let’s wrap up by going over the key points to remember.

Always track how long your zucchini gourds grow! They’re probably ready to harvest when they reach six to eight inches. Have a sharp pair of garden scissors ready when they grow to that length. And harvest at will!

Remember not to let your zucchini get too long. Zucchini seeds get too chewy after the gourds mature beyond eight inches. And the rind hardens, making it less palatable.

If you follow these tips? You’ll always know when to pick zucchini for the perfect harvest. Without second-guessing!

When researching when to harvest zucchini, we learned that Zucchini plants are monoecious plants. In other words, their plant produces both male and female flowers. Most plants in our garden have either male or female flowers, so we found the dual-sex nature of zucchini plants to be fascinating. We also read a spectacular zucchini entry in the Master Gardening Journal with excellent zucchini pollination tips. We recommend reading the guide if your garden lacks natural pollinators and bees!
