Did You Know?
1. In ancient Rome, cucumbers were primarily grown for their medicinal properties rather than for culinary purposes. They were used to treat a wide range of ailments, including headaches, bad breath, and even scorpion bites.
2. Did you know that cucumbers belong to the same family as melons, pumpkins, and zucchinis? They are all part of the Cucurbitaceae family, also known as the gourd family.
3. The world’s heaviest cucumber was recorded in 2015 and weighed a staggering 94.5 pounds (42.9 kilograms). That’s equivalent to the weight of two fully-grown golden retrievers!
4. While cucumbers are typically considered vegetables, they are actually fruits. More specifically, they are classified as “pepos,” which are a type of botanical berry with a tough outer rind.
5. Cucumbers have a fascinating cooling effect that goes beyond just how refreshing they taste. When applied topically to the skin, cucumbers can help reduce swelling and soothe sunburns due to their high water content and anti-inflammatory properties.
Types Of Cucumbers: Greenhouse Vs. Outdoor
Cucumbers are a versatile and popular vegetable that can be grown in both greenhouse and outdoor settings. Understanding the differences between these two types can help gardeners make informed decisions about which variety is best for their needs.
Greenhouse cucumbers are known for their long, smooth fruits and are often preferred by gardeners who want to control the growing conditions. These cucumbers do not require pollination and can be grown successfully in a controlled environment.
On the other hand, outdoor cucumbers are shorter, plumper, and have a rougher skin. These cucumbers require pollination and are best suited for growing in a traditional outdoor garden.
Planting Cucumber Seeds: Indoors And Outdoors
To get a head start on the growing season, cucumber seeds can be sown indoors in a propagator between March and April. If you have a heated greenhouse, seeds can be sown as early as February. The seeds should be sown on their sides at a depth of 1cm in pots of free-draining compost. The pots should be placed in a propagator or sealed inside a plastic bag at a temperature of 20°C until they germinate. After germination, the seedlings can be moved to a bright windowsill until they are ready to be transplanted.
For those who prefer to plant cucumber seeds directly outdoors, the ideal time is from May to June. The seeds can be sown in well-prepared soil at a depth of 1cm. It is important to ensure that the soil is well-drained and has been enriched with organic matter. It is also essential to provide proper spacing between the seeds to allow the plants to grow and spread.

Caring For Greenhouse Cucumbers: Planting And Maintenance
When it comes to growing greenhouse cucumbers, proper planting and maintenance are crucial for a successful harvest.
- Greenhouse cucumbers can be planted in late March or late May, depending on whether the greenhouse is heated or not.
- It is recommended to plant two cucumber plants per grow bag or 45cm apart.
- The potting compost should be kept moist to ensure proper growth and development.
In addition to regular watering, greenhouse cucumbers benefit from climbing for better yields. The main shoots should be trained to climb a vertical cane or string.
- It is important to pinch out the growing point at the top of the plant once it reaches the end of its support.
- This encourages the plant to produce side shoots, which will eventually bear fruit.
Regular spraying or damping down of pathways is essential to maintain a warm and humid environment in the greenhouse. On hot days, it may be necessary to use screening to protect the plants from scorching. Liquid fertiliser should be applied every two weeks to provide the necessary nutrients for healthy growth.
Growing Outdoor Cucumbers: Transplanting And Care
Outdoor cucumbers require a different approach to planting and care compared to their greenhouse counterparts. Before transplanting the seedlings into the garden, it is important to acclimatize them to outdoor conditions over 7-10 days. This process helps the plants adjust to the changes in temperature, sunlight, and wind.
When selecting a location for planting outdoor cucumbers, choose a sunny position that is sheltered from strong winds. The soil should be well-drained and rich in organic matter. Plant the cucumbers in single rows, with a spacing of 90cm between rows, allowing the vines to sprawl across the ground.
For outdoor ridge cucumbers, it is beneficial to pinch out the main stem after seven leaves have formed. This encourages the development of fruiting side shoots, which will ultimately yield a larger crop. It is important to note that outdoor ridge cucumbers require pollination by insects, so it is beneficial to plant flowers nearby to attract pollinators.
Harvesting Cucumbers: Tips And Timing
Knowing when to harvest cucumbers is crucial to achieve the best flavor and texture. Generally, cucumbers can be harvested around 12 weeks from sowing, but the individual variety and growing conditions may vary. It is best to harvest cucumbers while they are young and tender, before they produce seeds. Overripe cucumbers can become bitter and lose their crispness.
To ensure the highest quality harvest, cucumbers should be picked early in the morning when temperatures are cool. This helps to maintain their freshness and reduce the risk of wilting. When harvesting, it is important to use a sharp knife or scissors to cut the cucumber from the vine, leaving a small stem attached.
To promote continuous production, cucumbers should be harvested frequently. Regularly removing mature cucumbers from the plant encourages the development of new fruit. It is important to handle the cucumbers with care to avoid bruising or damaging the delicate skin.

Common Cucumber Pests And Diseases: Prevention And Treatment
Like any vegetable, cucumbers are susceptible to pests and diseases. Two common problems that gardeners may encounter are powdery mildew and verticillium wilt. Powdery mildew is a fungal disease that can affect cucumber plants, causing a white, powdery coating on the leaves. To prevent this, keep the soil moist and avoid getting the leaves wet while watering. Good air circulation and proper watering are essential to prevent stress on the plants. If powdery mildew does appear, chive or comfrey tea can be used as an organic anti-fungal treatment.
Verticillium wilt is another fungal disease that can infect cucumber plants through the roots. Signs of verticillium wilt include wilting and yellowing leaves, as well as dieback. If you notice any signs of verticillium wilt, affected plants should be removed along with any soil attached to the roots. Disposing of the infected plants and soil is essential to prevent the disease from spreading.
In addition to diseases, cucumber plants can also fall victim to pests such as whiteflies and aphids. Whiteflies can be particularly problematic for greenhouse-grown cucumbers. Using sticky sheets can help attract and trap whiteflies, although they may also trap beneficial insects. Planting basil and marigolds as companion plants can help deter or lure away whiteflies and aphids.
One common virus that affects cucumbers is the cucumber mosaic virus, which causes yellow mottling on leaves, stunted growth, and bitterness in the cucumbers. Aphids are the most common carriers of this virus, so it is important to control aphid populations to prevent the spread of the disease. Tools used around infected plants should be cleaned to prevent the transmission of the virus to other plants in the garden.
