Cucumbers are warm-season cucurbits that produce prolifically in Australian summers. Three main types are grown: Lebanese (short, smooth, seedless), Continental (long, thin-skinned) and pickling/gherkin varieties. Monoecious plants with separate male and female flowers on the same vine. Cross-pollinate readily with other cucumber varieties but NOT with melons, pumpkins or zucchini.

How to Grow Cucumber in Arid / Semi-Arid Australia
When to Plant
Two windows: September-October and February-March. Avoid midsummer extreme heat above 40C which causes bitter fruit.
- Soil
- Rich, well-drained soil with generous compost and well-rotted manure. Cucumbers are heavy feeders and need fertile, moisture-retentive soil.
- pH Range
- 6.0-7.0
- Sunlight
- Full sun (minimum 6 hours). In hot climates (tropics, arid), light afternoon shade reduces heat stress.
- Spacing
- 50cm apart, 120cm between rows
- Watering
- Heavy water demands. Deep, consistent watering at base is critical. Irregular watering causes bitter, misshapen fruit. Drip irrigation ideal. Water in morning to allow foliage to dry (reduces mildew).
Companion plants: Corn, Beans, Peas, Sunflower, Radish, Dill
Avoid planting near: Potato, Aromatic herbs (sage, mint), Melon (same family rotation issues)
