How to Grow Cucumbers
How to grow cucumbers: Most gardeners grow cucumbers from seed directly sown outside in the garden when temperature is suitable.
If you decide to start germinating your seeds indoors then sow cucumber seeds in pots or trays 0.8 inches (2 cm) deep. Optimal soil temperature for germination is between 73°F (22.7°C) and 87°F (30.5°C). Seeds will germinate in 6-11 days.
Cucumbers require 55-65 days to be ready for harvest from seed, depending on the cucumber variety and the weather during the growing season. They are relatively easy to grow and provide harvest quickly.
Optimal air temperature for growing cucumbers is between 71°F (21.6°C) and 80°F (26.6°C). Optimal night temperatures are between 62°F (16.6°C) and 67°F (19.4°C). Cucumbers can endure air temperatures as low as 60°F (15.5°C) during the night and up to 83°F (28.3°C) during the day.
Soil temperature during cucumber growth should be between 65°F (18.3°C) and 72°F (22.2°C) in optimal conditions, but can withstand soil temperatures as low as 61°F (16.1°C).
Required soil pH for cucumber growth is 5.9-7.0 but the optimal pH is 6.4-6.7.
Optimal sunlight for cucumbers is 6-9 hours per day. Cucumbers should be watered between 1-1.5 inches of water per week, adjusting for weather conditions and type of soil accordingly.
Cucumber spacing: When planting cucumber seeds directly into the ground sow seeds 0.8 inches (2 cm) deep spaced 15 inches (38 cm) apart with rows spaced 35 inches (89 cm) apart.
Cucumber classification: Cucumbers are classified into two groups, pickling and slicing. Slicing varieties are those cucumbers eaten fresh and tossed in salads, and pickling varieties, well, are for making pickles.
Cucumber varieties are also classified by size, how smooth or spiny their outer skin is, days to maturity, vine or bushy growth habits and by the amount of seeds they have, seedless and lots of seeds.
How to grow Cucumbers in your garden:
Cucumbers should not be allowed to grow on the ground or touch the ground. Most cucumber varieties will spread and take up lots of space, so growing them on a trellis, cage or even next to a fence will control their growth and also make sure fruit does not touch the ground.
