When to Pick Zucchini Squash And How to Harvest Them for a Perfect Crop

Zucchini squash grow very quickly. If you are not careful, a tiny zucchini one day can turn into a monster squash a few days later, so it is important to know when your zucchinis are ready so you can pick them at the perfect time. For an added delicacy, you can also pick the flowers and cook them up, too. 

Most zucchini plants start producing about 50 days after germinating. The ideal time to pick a zucchini is when it is 6 to 8 inches (15-20cm) long, with a bright and rich color.

The zucchini should be fairly dense, and the skin should be firm but not too hard. You can harvest zucchinis out of your garden until the first killing frost nips the plants and they start to die.

Let’s look in more detail at how to tell when your zucchinis are ready to pick, plus a few great tips for harvesting and preserving your bounty.

The Secret To Knowing When Zucchini Is Ready To Pick

The Secret To Knowing When Zucchini Is Ready To Pick

About 50 days after the seedlings first emerge, your zucchini plants will start to bloom and it won’t be long before you have dozens of little zucchinis just waiting to be picked.

  • A zucchini is ready to harvest when it is 6 to 8 inches (15-20cm) long. Of course, some varieties are different so check your seed packet for the ideal size for the type you are growing. Round varieties should be grown to about the size of a baseball. 
  • Most zucchinis should be a rich, dark green color when they are picked. Other varieties will be white or yellow. 
  • When it is ready to be picked, you will be able to nick the skin with your fingernail. Young zucchinis bruise and mar very easily, and even the scratchy leaves can damage their skin, so make sure to handle them with care.
  • The zucchini should be firm and feel dense and heavy for its size.

Sometimes a zucchini will hide and you won’t find it until it is a behemoth. Don’t worry! Large, overripe zucchinis are still edible but they might be mealy with large seeds. Try using these large zucchinis your favorite stuffed zucchini recipe. 

Pick your zucchinis regularly, every day, or every other day in warm weather. This will stimulate new flowers and you will have a continuous harvest throughout the growing season. 

Zucchinis will not tolerate frost, and both the plant and the squash themselves can be damaged by even a light frost.

As cold weather approaches, keep your eye on the forecast and pick all your zucchinis before a killing frost arrives.

Once you find the perfect zucchini hanging on the plant, it is time to harvest. Harvest zucchinis by grasping them firmly and twisting them off the plant, or by cutting them off the stem with a sharp knife or clippers.

  • Twisting is easy and does not require any tools, but you run the risk of the zucchini breaking. Broken zucchinis are still fine to eat, but they do not keep very long and the broken end might rot on the vine. When breaking off the zucchinis, you can also upset the roots of the plant if you twist too hard. 
  • To cut the zucchinis from the plant, use a pair of garden shears or a sharp knife. Simply snip the vine above the squash, leaving about 1 to 2 inches of stem still attached as this will help the zucchinis stay fresh for longer.

Zucchinis are experts at camouflage and they will often hide underneath the large leaves of the plant.

To make matters more interesting, these leaves and the stalks are very rough and will scratch your arms while you search for your harvest.

Make sure to wear a long sleeve shirt and gloves when harvesting zucchinis so you can really get in there and avoid missing any of the squash.

Did you know you can also eat the flowers from a zucchini plant? You can eat either the male or the female flowers.

  • Male flowers grow on a small stem attached to the main plant. To harvest squash flowers, cut the stem an inch or so below the flower and remove the stamen. Make sure to leave at least 1 male flower for every dozen female flowers on the plant to ensure good pollination and zucchini growth. 
  • Female flowers will develop into zucchinis, and they can be cut similar to male flowers or they can be carefully removed from an already developed squash. Also, you can pick the small zucchini with the flower still attached and cook them both together.

How To Store Zucchini

How To Store Zucchini

Once you have picked your zucchinis, you want to properly store them to get the most of your harvest. Zucchinis are best kept fresh in the fridge or frozen for long-term storage.

In The Fridge

Put your zucchinis unwashed in the fridge. If you have to wash off dirt, make sure they are completely dry prior to storage. Keep them for about 7 days. 

In The Freezer

Wash zucchinis before freezing. Cut your zucchinis into your preferred shape. They can be sliced, chopped, or shredded.

Freeze them on a cookie sheet and transfer them to an airtight container once frozen.

Can I still harvest zucchinis after a frost?

Zucchinis are very sensitive to frost and a light frost will quickly kill the plant. Even the vegetable themselves can easily be damaged by frost. While they are still edible, frosted zucchinis will often be hard and bitter tasting, or they will rot quickly if the damage was severe

What is the best time of day to harvest zucchinis?

What is the best time of day to harvest zucchinis?

Zucchinis can be harvested at any time of the day. Unlike soft, delicate greens, the tough veggie does not wilt very easily so zucchinis can be picked in the middle of the afternoon. Make sure to keep the freshly harvested zucchinis out of direct sunlight and chill them as soon as possible after picking them. 

How often should I harvest my zucchinis?

Harvest your zucchinis as often as you can. A consistent harvest will stimulate more flowers to develop, and you will get a more continuous harvest.

My zucchini broke when I twisted it off. What should I do?

The zucchini is perfectly fine to eat, but it should be eaten right away as it won’t store very well. If a large piece of the zucchini is still attached to the plant, remove it or it may rot and introduce disease. Consider cutting the zucchinis if you find the stems are particularly tough.

Yes, you can. Large, overripe zucchinis are still edible, though their quality will have diminished.

If the zucchini was left on the plant for upwards of 6 weeks, it may have viable seeds inside that you can plant in your garden next year (though at this point the zucchini will be bitter and inedible). 

Conclusion

Zucchinis are a great vegetable to grow. They are easy to cultivate and they are very versatile in the kitchen.

Knowing when to pick your zucchinis at the right time will give you the best tasting, most nutritious summer squash all season long.

It is always exciting digging through the massive foliage to find a perfectly ripe zucchini, and you might even stumble upon one hidden in the leaves and wonder how you ever missed such a giant!
