How To Grow Cucumber From Seed?

Planting something that requires little attention and grows quickly is a great way to ease into gardening. Thus, you may find that cucumbers are the missing piece to your vegetable garden.

Cucumbers are the way to go if you’re limited on space but still want to grow your own food. In contrast to several other fruits and vegetables, cucumbers can be eaten as soon as they are gathered. Think of it as a quick and easy snack you can have whenever you want.

Tools and materials you will need for Growing Cucumber from Seed:


  • Trowel
  • Watering can/hose
  • Knife/pruners
  • Pest/disease remedies (as required)


  • Cucumber seeds
  • Fertilizer and compost
  • The support structure (optional)
  • Mulch

Steps for growing cucumber from seed:

1. Plant the Seeds

Traditionally, cucumbers are cultivated in mounds or rows. Bush types and vining cucumbers are both available. Bush kinds can take up a lot of garden space even if they don’t require staking. Cucumbers that grow on vines are frequently left to sprawl out on the ground.

However, they take up valuable garden space when they spread on the ground and are more vulnerable to disease and pests. Teach vining cucumbers to climb a fence, trellis, or other solid support structure for a more confined growing area.

  • Before planting your seeds, wait until the earth has warmed to about 70 degrees Fahrenheit. Choose a location with plenty of sun exChoose an area that receives a lot of sunlight: posture, rich, well-draining soil, and a pH range of slightly acidic to neutral. Additionally, seeds can be planted inside approximately a month before the anticipated last spring frost date in your region.
  • Submerge seeds 1 inch deep. Make sure you know whether you are growing bush or vining cucumbers. While variability greatly influences spacing, the following are some broad ranges.
  • To plant seeds in rows, space them 3 to 5 feet apart, about 4 to 6 inches apart.
  • To make mounds, make small hills with a diameter and height of 1 to 1.5 feet, space them 1 to 2 feet apart, and plant 2 to 3 seeds per mound.
  • Two to three seeds per foot should be planted for support structures.

2. Thin the Seedlings

Typically, germination takes three to ten days. Cooler temperatures can slow down germination, likely to be prevented at temperatures below 50 degrees Fahrenheit.

It’s time to thin the seedlings once they reach a height of about 4 inches. Instead of plucking the seedlings, cut them off at the base with pruners to avoid disturbing the plant’s roots that you want to keep around the plants; use a mulch to keep the soil moist.

  • Thin seedlings for rows around 1 to 1.5 feet apart.

Remove everything except the strongest seedling from each mound for mounds.

3. Tend to the Plants

Keep the soil wet but not soaked. It’s good to water your plants once a week with about an inch of water, but water them more frequently during hotter months. A consistent watering plan is best since sporadic watering can produce bitter, strangely shaped cucumbers. To help prevent fungus illnesses, try to irrigate the foliage while keeping it dry.

When planting and all through the growing season, use a vegetable-specific organic liquid or slow-release granular fertilizer while adhering to the label’s directions. Compost can also be side-dressed on the plant to encourage development.

4. Watch Out for Pests and Diseases

Your cucumber plants will draw beneficial insects like bees as the growing season goes on, which helps with pollination and eventual fruit production. However, they might also bring in some diseases and pests. The pest that will most likely harm your crop is the cucumber beetle. Both plucking them off and parasitic nematodes can help control them. Tansies may be worthwhile growing near your cucumber crop because they are said to scare off cucumber pests.

A good variety can also aid in the prevention of pests and diseases. For instance, Asian cucumbers are less susceptible to disease than larger kinds. The common cucumber disease, mosaic virus, is not harmful to “Straight Eight.” Additionally, “Tasty Jade” thrives atop a trellis, freeing up space in the garden.

Crop rotation is a significant factor in preventing pests and diseases. Problems will arise if you grow pest-attracting gourds in the same spot yearly. Whenever possible, plant cucumbers after spinach or legumes, and in the winter, plant a nitrogen-fixing ground cover like clover in front of them.

5. Harvest

Take note of your cucumber variety’s mature size, typically 3 to 8 inches. As soon as they are this mature size, harvest them. The flavor and quality will suffer if you let them keep growing. The entire plant will cease producing cucumbers if only one matures long enough to develop seeds.

Every day, check the vines for cucumbers that can be picked. To cut the stem, use a knife or pruners because tugging them off can harm the vine. For just over a week, cucumbers can be kept in the refrigerator covered in plastic.

How long does it take to grow cucumbers from seed?

50-70 days

Cucumbers can have pest problems, but they are still relatively simple to produce from seed. In 50 to 70 days, most cultivars are ready for harvest.

How to grow cucumbers from seeds in pots?

Plant three seeds per pot, about a half inch deep, to sow cucumber seeds in a container. Till the seeds germinate, thoroughly water the soil and maintain a constant moisture level. Once the plants have established themselves and are thriving, you may need to remove all but one of them, depending on the cucumber variety and the size of the container.

How to grow cucumbers from seeds indoors?

Cucumber seeds should be sown in small pots 1-2cm (12-34in) deep on their side. A heated propagator or a bright sunny inside windowsill, keep them at 21°C (70°F). Sow between mid-February and mid-March if you’ll grow them in a heated greenhouse; if not, sow in April.


How many cucumbers does one seed produce?

Typically, the majority of cucumber types produce 10 fruits (cucumbers) per plant. That’s an average, though. This is what? Their tendrils are attached to trellises and other supporting structures after establishing roots in the ground.

How many cucumber seeds are in a hole?

How many cucumber seeds are sown in each hole? When using a brand-new, fresh package, only one cucumber seed should be planted in each hole. Plant two in each hole for elder plants, and if more than one germination occurs, later thin them.

What is the best way to grow cucumbers from seed?

Place two deep seeds about an inch (3 cm), then thoroughly water them. Put pots in a propagator for faster germination or wait until late spring to start growing cucumbers because they need temperatures of at least 68°F (20°C) to germinate. Remove the weakest seedlings when they emerge, leaving one per pot.

Should I soak cucumber seeds before planting?

Cucumber seeds typically grow without soaking, unlike large seeds like beans that may break. However, soak the seeds before planting if you desire rapid germination. After soaking, sow the seeds in well-draining soil with direct sunlight.
