Introduction
Cucumbers grow quickly and can be harvested in 50 to 70 days, depending on the variety. Warm soil and consistent watering are key for healthy growth and preventing bitter cucumbers. Cucumbers are ideal for spring and fall planting, offering multiple harvests in many regions.
If warm weather typically has you eager for a vegetable harvest, plant a vegetable that will give you fast results. Cucumbers germinate quickly from seed, and you’ll be able to harvest them in as little as 50 days, depending on the variety you choose. Since they’re planted just after the last spring frost, that means you could be digging out recipes for homemade pickles, salads, and tea sandwiches as early as June, depending on where you live. Some areas can even get a second harvest. Here’s how long it takes to grow cucumbers from seed to harvest so you can make the most of your crop.
How Long From Seed To Harvest?
Cucumbers are a quick crop, and in some regions, you can plant cucumbers later in the season for another round before cold weather sets in. These stages from seed to harvest can help you plan:
Germination: After planting seeds, cucumbers take about three to 10 days to germinate.
Growth And Flower Development: Vines begin to grow rapidly and yellow flowers start to appear between the second and fourth week.
Fruit Development: At the six-week mark, keep an eye out for tiny cucumbers tucked behind the flowers. These will enlarge fast.
Harvesting: Harvesting can begin between day 50 and day 70, depending on the variety. Slicing, pickling, and bush-type cucumbers are ready to harvest after 50 to 70 days from planting seeds. Climbing varieties take a little less time, about 50 to 65 days. Once flowering begins, the fruits develop quickly and are ready to pick in seven to 14 days. Keep an eye on them because they can become too large quickly. Harvest pickling varieties when the cucumbers are 2 to 4 inches long. Harvest slicing cucumbers when they are 6 to 8 inches long, firm, and dark green.
When To Plant Cucumber Seeds
Soil temperatures need to be warm, about 60ºF to 70ºF, to plant cucumber seeds in the garden. Wait until two to four weeks after the last frost in your area. You can also start seeds indoors two to three weeks before the last frost date.1 As seedlings develop, keep them at 70ºF. Start the seeds in peat pots so you can transfer the whole pot without disturbing the roots.
Because cucumbers grow quickly from seed, gardeners aren’t limited to growing them in the spring. Many can grow a successful fall crop as well. You’ll need to sow the seeds directly into the garden about 10 to 12 weeks before the expected first frost in your area.
Timing is usually around late July or early August and as late as September in mild climates. The warm soil will help seeds germinate, and the cooler temperatures mean you don’t have to worry about pests and diseases that are common during hot weather.
How To Ensure Healthy Growth
Consistent Watering
Cucumbers are made up of 95% water, so they need lots of it while they grow. Not enough water or an inconsistent schedule can turn them bitter and stunt their growth. Give them 1 inch of water each week, increasing to 2 inches during droughts and fruit production. Water in the morning deeply at the base of the plant using a soaker hose, avoiding wetting the leaves to prevent fungal diseases. Mulch around the base of the plant to retain moisture and keep the roots cool.
Prune Suckers
Snip any side shoots and suckers that develop on the first 2 to 3 feet of the vine so the plant will focus its energy on a strong main vine and fruit, to grow more quickly. Shoots that are left to develop will lead to sprawling vines and bushy growth that can create airflow issues and possible diseases.
Feed Regularly
Cucumbers are heavy feeders. Nitrogen nitrogen applied early in the growing season helps develop leaves and strong stems. Give the plant additional light feedings as it grows, but make sure to switch to a fertilizer that’s low in nitrogen and higher in phosphorus and potassium once flowers appear. Too much nitrogen at this time can limit fruit production.
Harvest At The Right Time
Once fruit appears, don’t let them turn yellow on the vine. Picking cucumbers when they are still green will give them the best flavor, and this signals to the plant to produce more fruits. Those left on the vine too long can taste bitter, tough, and have large seeds. Mature cucumbers that are left on the vine can cause the plant to begin seed production and slow fruit development. Harvest every two to three days.
