Cucumbers make delicious treats for the summers, but do you know how to tell when to pick cucumbers? You can’t enjoy the crispiest texture and the juiciest flavors unless you harvest them at just the right time.

Cucumbers are typically ready to be harvested anywhere between 50 to 70 days from planting. They are picked when the fruit is medium to dark green and firm. Pickling cucumbers are best picked when the fruit is about 2 inches long, while slicing cucumbers are best harvested when they are about 7 to 8 inches in length.

While these lengths give a fair idea on when to pick cucumbers, it also depends on the variety and how you plan on using the cucumbers you harvest. Overripe cucumbers are bitter in taste and generally not considered fit for consumption. Harvest your cucumbers at just the right time, depending on the variety you’re growing and how you plan on using them, to enjoy the best taste.

How To Tell When To Pick Cucumbers

Cucumbers are crisp, juicy, fresh vegetables that taste great in salads, pickling or eating right off the vine!

But when do you harvest them to experience all goodness packed in the fruit to its fullest?

Harvesting time varies with the variety you are growing and their usage.

Cucumbers come in two basic varieties: slicing cucumbers and pickling cucumbers.

Slicing cucumbers are primarily eaten fresh in salads or as a side to meals.

Pickling cucumbers, on the other hand, have a rough outer surface and are best eaten after blanching and pickling.

No matter which variety you grow, knowing when to harvest them is the key to the tastiest and freshest harvest.

Pickling cucumbers are typically picked when they reach about 2 inches in length.

If you plan on making dill pickles, pick cucumbers when they are about 4 inches long

Slicing cucumbers are longer and thinner than pickling cucumbers and taste best when picked at about 7 to 8 inches in length.

If you’re growing a slicing variety and you plan on pickling them, pick them a little earlier than their average harvest time.

Instead of letting them grow to 7 inches, pick them while they’re still young and about 5 to 6 inches long.

Similarly, pickling variety can also be used for eating fresh, but you’ll have to let the fruit stay on the vines a little longer for that.

Instead of picking them when they’re 2 to 4 inches long, let them grow a bit longer to about 5 to 6 inches before picking them for eating fresh.

Cucumbers take a long, warm growing season before they’re ready to be picked.

Depending on the specific variety, it can take anywhere between 50 to 70 days to come to harvest after planting the seeds.

Harvesting cucumbers at just the right time makes sure they are crisp, sweet and have no unappetizing bitterness in them.

Your entire cucumber harvest won’t ripen at the same time.

Once the harvest season starts, be vigilant in checking the vines every 2 to 3 days and pick them as each one is ready.

The fruit typically reaches its right size about 8 to 10 days after the female flower opens.

Slicing cucumbers are ready to be harvested when they are about 1.5 to 2 inches in diameter, dark green and firm.

If the fruit is left on the vine beyond its right size, it will turn soft and will start showing signs of yellowing.

Over-mature cucumbers are soft, spongy and have large, tough seeds, not fit for eating.

The fruit should be picked before the skin starts turning yellow.

Once the fruit starts turning yellow, it will develop bitterness rendering it unsuitable for eating.

Consider first signs of yellowing as an indication that the fruit has crossed it’s harvest time and aim at picking it before this happens.

Over-mature cucumbers aren’t just unsuitable for eating but they will also inhibit further fruit set on the vine.

If there are over-mature cucumbers on the vine, pick and discard them even if you don’t plan on consuming them.

Removing them from the vines will help the vine concentrate its energies on the younger fruits that are still developing.
