How to Grow Cucumbers Indoors in Containers
Growing cucumbers indoors can be a rewarding and fun experience for gardeners who want to enjoy fresh, flavorful cucumbers all year round. Cucumbers are warm-season plants that require plenty of light, warmth, and water to thrive. While growing cucumbers outdoors can be challenging in areas with cool or unpredictable weather, growing them indoors allows you to control the growing conditions and provide the plants with the ideal environment they need to grow and produce fruit.
Indoor cucumber plants can be grown in containers or hydroponic systems, which are perfect for small spaces such as apartments or homes without a garden. With the right care and attention, indoor cucumber plants can produce fruit for several months, providing a steady supply of fresh cucumbers for salads, sandwiches, and other dishes.
To grow cucumbers indoors, you will need to provide them with adequate light, warmth, water, and nutrients. You’ll also need to pay attention to their growing habits and prune them as needed to keep them healthy and productive. With a little patience and a lot of love, you can enjoy the taste of fresh, homegrown cucumbers no matter where you live.

The methods and principles for growing cucumbers indoors are very similar to that of many indoor plants.
There are certain requirements that you should follow if you want to get the most out of your efforts.
The cucumber is thought to originate from Eastern Africa/Asia and has been grown indoors by people, it is thought, as far back as the ancient Egyptians.
Gardening Basics to Get Started Growing Cucumbers indoors in your Home
To start cucumbers from seed, fill a small pot with potting soil and plant one or two seeds per pot. Place the pots in a warm, sunny location and keep the soil moist. Cucumber seeds will typically germinate within 7-10 days.

Choosing & Planting the seeds
What you need to know about which seeds you should pick for the best crop. As with most indoor vegetables and fruit, it is very important to choose a variety that suits your growing environment as well as the conditions you can provide in order to get the best of the seeds that you plant. With cucumbers that is no different.
Most varieties of cucumber plants in pots grow to several feet in height. They also produce crawling vines that hoist the plant up and out (usually these are trained around a trellis). They are also notorious for sending huge tap roots down into the soil below them. For the indoor gardener, there are varieties of cucumbers that are much more suited to the space typically provided by the average home.
For an indoor cucumber plant, you should choose a bush variety that is way more compact than the standard variety. They also require less soil and can still bear cucumbers of normal size. You can plant these in a 7-inch pot.
Just sprinkle some seeds over loosened soil and then cover them with another inch just to make sure they are covered. Cucumber plants usually germinate within 10 days provided they have the right conditions and ‘should’ take around 60 days to fully mature.
You should aim to grow AT LEAST 2 plants for pollination purposes.

Light & Temperature
How to provide the correct environment for your plants to ensure growth.
In the early stages of growth, if you can provide continuous light for the plants then do so as this will provide stimulation. If this is not possible, then provide light for as long as possible for a similar effect.
Tip to growing cucumbers in Pots –
You can also provide high temperatures of around 25-30 degrees Celsius for a further boost in growth. However, this is not completely necessary! In the latter stages, especially when fruiting, the plants will need consistent, strong light for 8 hours a day, which must need to be supplemented by a grow light if natural light will not suffice.
Note – With Cucumbers plants, it is still possible to grow the fruit in less than optimum conditions, however, you will find that the production of the plant is greatly reduced. E.g., You can also compensate for low lighting with longer periods of lighting around 16 hours.
-
Watering
Cucumbers require consistent moisture to grow properly. Keep the soil consistently moist, but not waterlogged, by watering deeply once a week or more frequently if needed. Be sure to water the soil around the plants rather than the leaves to avoid moisture-related diseases.
To water cucumber plants indoors, you can follow these tips:
-
Water regularly: Cucumber plants need regular watering to stay hydrated, especially during the hot summer months. Aim to water your plants at least once a day or more frequently if the soil feels dry.
-
Avoid overwatering: While cucumber plants need regular watering, it’s important not to overwater them. Overwatering can lead to root rot and other problems. Check the soil moisture level regularly, and only water when the top inch of soil is dry.
-
Water at the base: Water the plants at the base, rather than from overhead. This will help prevent moisture from getting on the leaves, which can lead to disease.
-
Use room temperature water: Use room temperature water when watering your cucumber plants. Cold water can shock the roots, while hot water can scald them.
-
Use a watering can or drip system: Use a watering can or drip irrigation system to water your cucumber plants. This will help ensure that the water reaches the roots and is evenly distributed.
-
Adjust watering based on plant growth: As your cucumber plants grow, their water needs may change. Be prepared to adjust your watering schedule accordingly.
-
Watering techniques specifically for cucumbers.
-
Cucumbers are very thirsty plants and will require large amounts of water especially when they begin to fruit.
-
Keep the soil completely moist at all times so that the plant can constantly draw water for the fruit, etc.
-
Feeding & Nutrition
How to make sure that your plants get all the nutrients that they need in order to survive and produce juicy fruits? Cucumber plants will require feeding with a Nitrogen-based plant food dissolved in water. Two feedings should carry the plant through to maturity.
To fertilize cucumber plants indoors, you can follow these steps:
-
Choose a high-quality fertilizer: Look for a balanced fertilizer with a ratio of nitrogen, phosphorus, and potassium (NPK) of 20-20-20 or 15-15-15. You can also use a slow-release fertilizer to provide nutrients to your plants over a longer period.
-
Dilute the fertilizer: Follow the instructions on the fertilizer package to determine how much fertilizer to use per gallon of water. Typically, you’ll need to use 1-2 tablespoons of fertilizer per gallon of water.
-
Water the plants: Water the plants thoroughly before applying the fertilizer. This will help prevent the roots from burning.
-
Apply the fertilizer: Pour the diluted fertilizer solution around the base of the cucumber plants. Make sure to avoid getting any fertilizer on the leaves or stems, as this can cause damage.
-
Repeat as needed: Fertilize your cucumber plants every two weeks throughout the growing season, or as recommended by the fertilizer manufacturer.
In addition to fertilizing, it’s important to provide your cucumber plants with adequate light, water, and temperature to ensure healthy growth.
-
Pollination
How to ensure that your plants are productive in their indoor environment. Cucumber plants produce both male and female flowers. Male flowers outnumber female flowers which can be identified by the tiny cucumbers growing behind the flower.
To pollinate your plant/s, pollen must be transferred from the male flowers to the female flowers. To do this clip a male flower off the plant and peel back the petals to use the flower as a brush. Ideally, you should use males and females from alternative plants for the best results.

How to Prune Cucumber Indoor
Pruning cucumber plants can help increase fruit production and keep the plants healthy. Here’s how to prune cucumber plants indoors:
-
Identify the main stem: The main stem is the central stem of the plant that runs from the soil to the top of the plant. It’s important to leave this stem intact, as it’s responsible for carrying water and nutrients to the rest of the plant.
-
Remove side shoots: Side shoots, also known as suckers, grow from the base of the leaves and can compete with the main stem for resources. Use a clean, sharp pair of pruning shears to cut off any side shoots that are growing from the base of the plant.
-
Remove old leaves: As cucumber plants age, the lower leaves may turn yellow and die off. Use pruning shears to remove any yellowed or dead leaves from the plant.
-
Pinch off the growing tip: Once your cucumber plants reach the desired height or have produced several fruits, you can pinch off the growing tip at the top of the main stem. This will help redirect the plant’s energy toward producing fruit.
-
Train the plant: As your cucumber plants grow, use plant ties or stakes to train the main stem to grow upward. This will help keep the plant upright and make it easier to harvest the fruit.
By pruning your indoor cucumber plants regularly, you can help keep them healthy and productive. However, it’s important not to prune too aggressively, as this can damage the plant and reduce fruit production.
-
Harvesting
How to collect your fruit safely and how to maximize crop growth for the future. Once the cucumbers reach a desirable size, pick the fruit by cutting the stem with hand shears roughly an inch or so from the end of the fruit. You should remove any fruit that shows signs of yellowing as this can cause the entire plant to stop growth and production.
Conclusion
Growing cucumbers indoors is a great option for gardeners who have limited outdoor space or who want to enjoy homegrown produce during the winter months. With a little patience and knowledge, anyone can grow cucumbers indoors and enjoy the taste of fresh, delicious cucumbers all year long.
