Cucumber Growing Information
Cucumbers are tender annuals that grow best in temperatures ranging from 15°-32° C.
- Sow cucumber seed in the garden or set out transplants 3 to 4 weeks after the average last frost date in spring.
- The ideal soil temperature for growing cucumbers is 21°C.
- Sow cucumber seed indoors as early as 6 weeks before transplanting into the garden.
- Protect cucumbers from unexpected frost or chilly night-time temperatures early in the season. Use floating row covers or plastic tunnels to keep the chill away.
- Cucumbers require 55 to 65 frost-free days from sowing to reach harvest.
Where to plant?
- Grow cucumbers in full sun. Cucumbers can tolerate partial shade.
- Cucumbers prefer loose, well-drained soil rich in organic matter. Prepare planting beds in advance of planting by adding (5-7cm) of aged compost, commercial organic planting mix, and aged manure to beds.
- Place black plastic sheeting over the planting bed in spring to warm the soil in advance of planting.
- Cucumbers prefer a soil pH of 5.5 to 6.8. Cucumbers can tolerate alkaline soil to a pH of 7.6.
- Set trellises or supports in place to grow cucumbers up or mound the soil to create a small hill off which cucumber vines can run. Use a trellis 1.2-1.8m tall. Create a mound at least 40cm across and several inches high; space mounds 1.2-1.8m apart.
- Keep the soil evenly moist with regular watering. Do not let the soil dry out. Cucumbers are about 95 percent water and require regular water for fast, even growth.
- Set a soaker hose or drip irrigation at the base of plants. Give cucumbers at least 1 inch of water each week during the summer.
- Always water at the base of plants. Moisture on cucumber leaves can result in fungal diseases such as powdery and downy mildew.
- Leaves may wilt in the afternoon in hot weather; that is because plants are taking up water faster than roots can supply.
- If plants are wilted in the morning, the soil is too try and needs immediate water.
- Mulch around plants to slow soil moisture evaporation and to avoid soil compaction caused by heavy watering.
- Too little water or inconsistent watering can cause cucumbers to become oddly shaped or bitter tasting.
- An easy way to measure soil moisture is to stick your index finger in the soil; if your finger comes away dry, it’s time to water.
