Cucumber Plant Cultivation In A Greenhouse?

Cucumbers grown in a greenhouse are typically for fresh use and not pickling. Slicing varieties are longer than those grown for pickling. In a commercial greenhouse, a wire is placed about 10 feet above the plants, and individual plants are run up to the wire. Growing cucumbers in a greenhouse requires careful attention to their daily needs, as these plants thrive under specific conditions.

Cucumbers can be grown indoors or purchased as young plants or grafted plants in spring or early summer. To plant cucumbers, seedlings should be planted when they have two or three leaves and placed 60cm apart in a greenhouse border enriched with garden compost. The greenhouse kit should allow at least six hours of direct sunlight.

To plant cucumbers, insert a sturdy bamboo cane up to the roof or attach a vertical wire or string from the roof, secured at ground. Germination usually takes 5-7 days, and plants should be kept at a temperature above 15 ℃. Regular watering and mulching are essential for maintaining moisture and weed-free conditions.

The basics of greenhouse cucumber production include seeding, training, pruning, spacing, the greenhouse environment, fertilization, and planting. When planting, canes can be inserted into the soil or strings hung from the roof to train vines upwards. Water thoroughly and keep the soil moist but not wet. For optimal growth, use fertile soil with a pH level of 5.5 to 6.8.

How hot is too hot for cucumbers?

Cucumbers, like all crops, have a preferred temperature range of 21-26°C (70-80°F) for their growth. They can withstand a wider range of 15-29°C (60-85°F). They are sensitive to frost, and low temperatures can cause wilting. For cucumber germination, the ideal temperature is 15-29°C (60-85°F), with soil temperatures around 21°C (70°F) or higher. Germination generally occurs slower in lower temperatures.

Do cucumbers grow well in a greenhouse?

Growing cucumbers in a greenhouse offers several benefits, including avoiding cold and frost, utilizing minimal space, and utilizing vertical space through a trellis. Cucumbers grow quickly, making them ideal for pickling or snacking. Some suitable cucumber varieties include miniature cucumbers like Mini Munch or Picklebush, European or English cucumbers like Diva or Passandra, dwarf bush cucumbers like Bush Champion or Fanfare, slicing cucumbers like Sweet Success or Sweet Green, and hybrid cucumber varieties designed for controlled environments.

Miniature cucumbers, such as Mini Munch or Picklebush, produce small, crisp cucumbers ideal for pickling or snacking. European or English cucumbers, such as Diva or Passandra, produce long, slender, and seedless fruits that yield high yields in greenhouses. Dwarf bush cucumbers, like Bush Champion or Fanfare, are bred specifically for smaller spaces like greenhouses. Slicing cucumbers like Sweet Success or Sweet Green offer excellent flavor and a steady supply of crisp, juicy cucumbers. Hybrid cucumber varieties, with their disease resistance, high productivity, and exceptional flavor, are also ideal for greenhouse gardens.

Can I grow tomatoes and cucumbers in the same greenhouse?

Tomatoes and cucumbers thrive in greenhouses due to their similar growing conditions. To prevent competition, plant them in separate areas. Other plants like Borage, Calendula, Lettuce, Fennel, Dill, Onion, and Garlic can also be grown in a greenhouse. Polyculture or mixed culture gardening can be beneficial both outside and inside the greenhouse, as it allows plants to grow together without competing for nutrients and space.

Should I put coffee grounds in my cucumber plants?

Coffee grounds are neutral to slightly acidic, which can affect soil pH. Acidic-loving plants like azaleas, blueberries, hydrangeas, rhododendrons, and roses can benefit from a sprinkling of coffee grounds around their base. Vegetable crops like carrots, cucumbers, peppers, potatoes, and radishes may also benefit from coffee grounds. However, tomato plants may not benefit from coffee grounds. Plants that prefer drier soil, such as cacti and succulents, should avoid using grounds.

Houseplants that prefer acid soil, such as African violet, croton, gloxinia, monstera, peperomia, and philodendron, may benefit more from coffee grounds. However, aloe vera, orchids, and pothos should not be used.

How do you maximize the yield of cucumbers?

The pruning of lateral growth points between the leaf, tendril, and fruit of cucumber plants, regardless of whether they are cultivated in a greenhouse, hoophouse, caterpillar tunnel, or backyard containers, has been observed to promote upward growth and enhance yield.

Should I pinch off cucumber flowers?

It is recommended that flowers be pinched off at this juncture, allowing the plant to undergo substantial growth before attempting to produce fruit.

What is the trick to growing cucumbers?

To grow cucumbers, ensure they are well-watered, fed with a high nitrogen feed every two weeks, and have some shade to avoid scorching. Encourage greenhouse varieties to climb for increased yields. Harvest fruits early in the day and frequently to get more fruits during the season. Enjoy your cucumbers sliced into sandwiches or added to long cold summer drinks.

What is the best fertilizer for greenhouse cucumbers?

When planting cucumbers, compost or well-rotted manure can be used as a soil amendment, or granular fertilizer can be added to the soil. The Expert Gardener All Purpose Plant Fertilizer 10-10-10 is a good option for planting cucumbers. Once the cucumber plants are flowering, a high-potassium fertilizer is recommended for tomato growth. This type of fertilizer is typically used in liquid form and mixed with water for watering. Other high-potassium fertilizers include wood ash or kelp meal. The Great Big Tomatoes Fertilizer is an example of a liquid tomato feed.

Natural fertilizers like compost or feed from nettles can also be used to feed cucumbers. These simple, nutrient-rich teas can be made by cutting the plant’s leaves and mixing them with water. Regular watering and fertilizing are essential for cucumber growth, and pruning can help maintain productivity. Cucumber companion planting can also help combat pests or diseases, maximizing yield.

Why are my cucumbers dying in my greenhouse?

Cukes require ample water, but should not get on their stems or leaves. They thrive in humid conditions, so increasing humidity in the greenhouse can help. Ensure air flow during high temperatures. Balancing protection with light needs is crucial. Protecting cukes with coolie hats made from newspaper can help. Wait until the plants are flowering or fruiting, but using a weak solution, about half of the recommended dosage, can be beneficial if the plant is not doing well. Remember to balance the need for water with the plant’s need for light.

How many cucumbers per plant in a greenhouse?

Harvesting cucumbers is a rewarding experience, with 20 to 50 per plant. They can be harvested 12 weeks after planting, when they reach six to eight inches. It’s best to pick them fresh, before they show signs of bearing seeds, as older fruits can be bitter. Frequent harvesting promotes an endless yield. To harvest, use a sharp knife at the base, and early morning harvests are recommended. Seeds can last for three years or more if properly stocked.

Do cucumbers like morning or afternoon sun?

Cucumbers require a minimum of eight hours of sunlight per day, with morning sunlight being optimal for the removal of dew and the prevention of mildew. The practice of rotating the location of cucumber cultivation has been demonstrated to be an effective method for preventing soil-borne diseases and overwintering insects.
