Organic Cool Customer Cucumber Seeds

Cool Customer cucumber is an exceptional, improved pickler that will produce heavy crops of uniform cucumbers for jars of tasty pickles over a long harvest period. Blocky, 4–5″ fruits have small seed cavities for the perfect crunchy bite!

Cucumbers are happiest grown in full sun with a sturdy structure to climb. Light pruning can increase airflow and prevent foliar diseases. Do not overhead water. Harvest frequently — the more you harvest, the more you will get!

Planting by Zones

Zones 9-10

• Cucumbers are easily direct sown or transplanted. This warm-season crop should be grown when soils are at a minimum temperature of 70°F.

Zones 2-8

• Start 3-4 weeks before transplanting. Soil should be warm, and overnight temperatures should not drop below 60 degrees for the happiest plants.

Planting Cucumber Seeds

• Seeds are very easy to direct sow. For Zones 9 and 10, sow seeds in deeply irrigated soils to guarantee even and quick germination. Plant seeds 6″ apart.
• Fertilize regularly with an organic liquid fertilizer once seedlings have germinated and are about 4″ tall.
• Transplant out when plants are 5-6″ tall and healthy. Space at least 6″ apart.

Succession Planting Cucumber

• Plant every 21 days for continuous crop to harvest.

Growing Cucumber

• Cucumbers enjoy warm temperatures, good fertility, and consistent moisture. For Zones 9 and 10, this means frequent watering or running irrigation. DO NOT overhead water as this promotes disease—water at the base of the plant.
• Side-dress with a granular organic fertilizer if you believe your soil has low fertility.
• Except for some bush varieties, you will need a trellis for support. If space is limited, use our Tomahook system to maximize space and keep your garden area tidy. Practicing good garden hygiene will prevent diseases.

Growing Cucumber in Containers

• Cucumber can be planted in a container but should be in a large container with good soil. Cucumbers need regular moisture to be happy, and containers dry out very quickly in the heat of Zones 9 and 10. Be sure to mulch heavily and add compost to your container to retain moisture between waterings.

Harvesting Cool Customer Cucumber

• Harvest small for maximum production and the best flavor, about 15-18 days after pollination. Check your plants every 2-3 days for more fruit. There is always one hiding! Leaving several ripe cucumbers on the plant will take away the energy needed to develop more fruit.

 Southern California Pro-tips

• Succession plant several times throughout the warm season in areas of Zones 9 and 10 to enjoy a large harvest.

Companion Flowers/Crops

• Plants like alyssum and gaillardia are stunningly beautiful planted with trellised vines.
