Cucumber Armenian

Climate

Temperature: 

• Cucumbers need warm temperatures between 20°C to 30°C. They thrive when daytime temperatures are consistently above 15°C.

Frost Sensitivity: 

• Cucumbers are sensitive to frost; plant them after the last frost date in your region.

Soil Requirements

Soil Type: 

• Well-draining loamy soil is ideal.
• Heavy clay soils can be improved with compost or organic matter.

Soil pH: 

• Aim for a pH between 6.0 and 7.0 to promote nutrient availability.

Nutrients: 

• Cucumber plants have high nutrient demands, particularly for nitrogen and potassium.

Soil Preparation

Testing Soil

• Conduct a soil test to determine pH and nutrient levels.

Amending the Soil

• Add compost, aged manure, or a balanced organic fertilizer to increase nutrient levels.
• Work these amendments into the soil to improve its texture and nutrient content.

Planting Cucumbers

Direct Sowing: 

• In most Australian regions, cucumbers can be sown directly into the garden from late spring.

Indoor Start: 

• For a head start, sow seeds indoors 3-4 weeks before the last frost date, using seedling trays with seed-raising mix.

Seed Spacing: 

• Plant seeds 5 mm deep, 60 cm apart in rows or in clusters (3-4 seeds per mound).

Row Spacing: 

• Space rows 60 cm apart for adequate airflow and growth.

Transplanting: 

• If you started seeds indoors, transplant seedlings when they have at least 2-3 true leaves.

Watering

Consistency: 

• Aim to keep the soil consistently moist, especially during flowering and fruit development.
• Water deeply once a week, and more often in hotter conditions.

Irrigation Method: 

• Drip irrigation or soaker hoses are ideal as they minimize leaf wetness, reducing disease risk.

Fertilisation

Initial Application: 

• Apply a balanced fertiliser or a fertiliser high in potassium at planting.

Subsequent Feeding: 

• Fertilise again every 4-6 weeks using liquid fertilisers, especially during flowering and fruit setting.

Mulching

• Use a layer of organic mulch (straw, wood chips, or grass clippings) around the base of the plants to retain moisture, suppress weeds, and regulate soil temperature.

Companion Planting

Radishes: 

• Help deter cucumber beetles and can aid in moisture retention.

Nasturtiums: 

• Act as a trap crop for aphids, attracting them away from cucumbers.

Beans: 

• Provide nitrogen to the soil and can act as a natural trellis for cucumber vines.

Corn: 

• Offers natural support for climbing cucumber plants and creates a microclimate for warmth.

Marigolds: 

• Help repel nematodes and other pests.

Common Pests

Cucumber Beetles: 

• These pests can be controlled using insecticidal soaps or neem oil. Handpicking can also be effective.

Aphids: 

• Manage with insecticidal soap or introduce beneficial insects such as ladybugs.

Spider Mites: 

• Keep leaves hydrated to deter these pests; if they appear, use miticides or beneficial predatory mites.

Common Diseases

Powdery Mildew: 

• Maintain good air circulation, avoid overhead watering, and remove infected leaves. Resistant varieties can help.
• Trellising can increase airflow as well as saving space.

Fusarium Wilt: 

• Rotate crops and keep the garden free of debris to prevent soil-borne diseases.

9. Harvesting Cucumbers

Timing: 

• Harvest cucumbers when they are firm and before they start to yellow.
• For slicing cucumbers, aim for a length of 15-22 cm.

Increase Yield:

• Picking regularly promotes further production. Use scissors or shears to avoid damaging the plant.
