Planted 2 cucumber plants in the greenhouse, prepared in buckets, the first one is over 30cm (12in) at the base and 15cm (6in) tall, the second one has a normal base but measures only 15cm (6in). They were installed in the greenhouse about 3 weeks ago, these are not the first ones I plant (other varieties), and it seems like they don't want to grow anymore. I won't grow this kind of cucumber again.

Description

Cucumis sativus 'Louisa' F1 is a high-quality hybrid variety that is very resistant. It is a prolific greenhouse cucumber that produces long dark green fruits, approximately 40cm (16in) in length. The flesh has no bitterness in its flavour. This variety can be grown on trellises. The sowing period extends from March to May for a harvest from July to October.

 

Cucumbers prefer light, loose, moist, and humus-rich soils. They thrive in sunny exposures and temperatures between 18 to 22°C (64.4 to 68°F). They are fairly water-demanding vegetables that need regular watering. Once there are 2 to 3 fruits formed per stem, pinch the top of the stem. This will prevent an excessive number of fruits and spread out the harvest over time.

Along with tomatoes, cucumbers are one of the staple fruits of summer. They are refreshing, low in calories, and can be enjoyed in salads or on their own, with, for example, a yogurt, lemon and dill sauce.

There are two main types of cucumbers: "forcing" varieties, which are intended for greenhouse cultivation, and those that are adapted to outdoor cultivation. They can be smooth or spiny, long or semi-long. In addition to these classic varieties, there are also more "exotic" cucumbers such as the Kenyan Cucumber or the Snake Cucumber, which are generally more heat-demanding.

NB: This variety is labeled F1 for "F1 hybrid" because it is a variety resulting from the cross-breeding of carefully selected parents to combine their qualities. This results in a variety that can be particularly flavourful and/or early, while also being resistant to certain diseases. Sometimes criticised or wrongly associated with GMOs, F1 hybrid seeds are appreciated both for their homogeneity and their resistance. However, their qualities do not pass on to the next generations. It will therefore not be possible to save the seeds for future sowing.

 

Harvest: cucumbers should be harvested when they have reached their final size, before their colour turns yellow. Regularly harvest to encourage the formation of new fruits.

Storage: cucumbers can be stored in the refrigerator for several days. To enjoy your harvest for longer, you can also preserve them in jars through lacto-fermentation or in vinegar.

Gardener's tip: like all members of the Cucurbitaceae family, cucumbers can be susceptible to powdery mildew, which is a white fuzz on the foliage. It is advisable to remove heavily affected leaves and spray with wettable sulphur every 2 weeks. In case of minor infestation, you can treat the plants with skimmed milk diluted to 10 to 20% in rainwater. As a preventive measure, avoid watering the foliage and ensure good ventilation in your greenhouse if growing under cover. Spraying with a horsetail decoction can also strengthen foliage resistance.

Planting and care

Sowing

Cucumber germination occurs at a temperature between 16 to 35°C (60.8 to 95°F). The emergence of seedlings generally takes 8 to 10 days.

Sow from April to June, in pots or in open ground.

Prepare your pots one month before the planned planting date. Place 2 or 3 seeds in special sowing compost and water with a very fine spray. When two true leaves appear, keep only one plant per pot. Keep the young plant at a mild temperature, ensuring that the substrate remains moist but not waterlogged.

Sowing in open ground is done later, in warm soil. Sow in a small hole with 2 or 3 seeds and proceed as for sowing in pots.

When planting or direct sowing, maintain a distance of 1m (3ft) between each row and 50 to 60cm (20 to 24in) between each plant.

 

Cultivation

Cucumbers are a fairly demanding vegetable that require well-fertilised soil. It is wise to add mature compost (about 3 kg per m2) in autumn, by raking the soil to a depth of 5cm (2in), after having loosened the soil as with any vegetable cultivation. They prefer neutral soils (pH 7) but will also thrive in slightly acidic or alkaline soil (pH between 5.5 and 7.5).

Cucumbers can be grown flat. To save space, use their climbing nature by training them on a frame covered with wire mesh, inclined at 45%. This will provide beneficial shade for lettuces. You can also grow cucumbers up a teepee.

When the plants are vertically trained, concentrate on a single stem. Pinch this stem at a height of 2.5m (8ft). When grown flat, pinch above the second leaf to obtain two stems, which will themselves be pinched above the 4th leaf. The final pruning involves cutting above a leaf for each formed fruit.

Cucumbers pair well with corn, but avoid planting them near tomatoes and potatoes.
