Cucumber Growing Guide Cucumis sativus Crop Rotation Group Cucurbits (Squash family) ● Soil Soil enriched with plenty of compost. Position Sunny, sheltered site Frost tolerant No. Feeding When flowers start forming, feed with slow release potassium-rich organic fertiliser. Fortnightly liquid feed from mid summer. Spacing Single Plants: 60cm (1' 11") each way (minimum) Rows: 60cm (1' 11") with 60cm (1' 11") row gap (minimum) Sow and Plant In frost areas, sow under cover in seed trays in early spring. Plant out after last frosts. In frost free areas sow directly into the soil in early spring. Our Garden Planner can produce a personalised calendar of when to sow, plant and harvest for your area. Notes Support plants well so they can climb upwards, even when the cucumbers get large. This also protects the cucumbers from slugs. Occasionally a plant can produce very bitter cucumbers so always test a bit before serving to others! Harvesting Cut the cucumbers off the plant when they are still quite young, otherwise the skin becomes hard and will need peeling. More cucumbers will then be produced.
