Background

'Silver Slicer' is a pale, creamy-yellow slicing cucumber with thin skin and a mild flavour that never turns bitter. The fruits are best picked at 6 to 8 inches, when they are still pale; left longer they yellow and seed up. It is a vigorous vine that climbs 6 feet or more on a trellis.

Cucumbers need warm soil, above 65°F, and sulk in cold ground. Sow directly once the soil has warmed, a week or two after last frost, or start indoors three weeks earlier in pots and transplant carefully, because the roots resent disturbance. Trellising keeps the fruit straight and clean, improves air movement and makes the harvest easy to see. Water deeply and consistently; an uneven supply is the usual cause of bitter fruit.

Sow a second batch three weeks after the first and a third in early summer; young plants outproduce old ones that have set a lot of seed. Pick every other day once fruiting starts, since a vine that is allowed to ripen fruit slows down.

Care guide
SunFull sun - 8+ hours for best production
WaterConsistent and deep; irregular watering causes bitterness
SoilRich, well-draining, warm; mulch to retain moisture
Spacing12 inches on a trellis; 2–3 feet if allowed to sprawl
HeightClimbing vine - 6+ feet on a trellis
Zone3a – 10b
WinterAnnual - compost after first frost.
Direct sow
Seasonal tasks
spring
sowSuccession sow - direct sow after last frost when soil is above 65°F; or start indoors 3 weeks early for transplanting; sow every 3 weeks through about 13 weeks before fall frost
summer
cutHarvest daily - cucumbers left too long signal the plant to stop producing; pick while still pale yellow
sowSuccession sow - direct sow after last frost when soil is above 65°F; or start indoors 3 weeks early for transplanting; sow every 3 weeks through about 13 weeks before fall frost
watchLast sow (~13 weeks before fall frost) - cucumbers need 50–70 days and fruit poorly as the season cools; later sowings won't crop before first frost
Common problems

Powdery mildew

Symptoms

White or grey powdery coating on leaves - usually starting on older growth in humid conditions or when nights cool.

Treatment

Improve air circulation by thinning plants. Apply neem oil or potassium bicarbonate spray at first sign. Avoid overhead watering.

Downy mildew

Symptoms

Yellowing on top of leaves with grey-purple fuzz underneath. Spreads rapidly in humid conditions.

Treatment

Remove affected leaves. Improve air circulation. Avoid overhead watering. Copper spray as preventive.
