How to Grow White Wonder Cucumbers

Growing white wonder cucumbers is very similar to growing regular cucumbers. They require lots of light, lots of water, and lots of fertilizer - as with most vegetables. However, because of their long vines, white wonder cucumbers can be trellised easily, which not only helps the fruits to grow straighter, and protects them from blemishes and diseases caused by cucumbers touching the ground directly. White wonder cucumbers require lots of space in the garden - at least 10 inches apart when grown on trellises, and at least 24 inches apart if grown in the ground, so they are not ideal for small spaces.

Light

As with most vegetables, white wonder cucumbers require full sun for best production. At least six hours of direct sunlight a day is ideal. Stunted growth may be an indication that your white wonder cucumbers are not receiving enough light.

Soil

White wonder cucumbers require loose, well-draining soil that is highly fertile. Before planting, ensure that the soil is tilled and freshly amended with compost or manure to replenish the soil’s nutrients. 

Water

Water white wonder cucumbers deeply at least three times a week. In especially hot or dry periods, white wonder cucumbers may require daily watering to ensure they don’t dry out. 

Temperature and Humidity

Cucumbers thrive in heat, and white wonder cucumbers are no exception. Ideally suited to growing temperatures between 60-90 degrees Fahrenheit, white wonder cucumbers appreciate warm, humid environments. They are often referred to as ‘Southern Heirlooms’ because they grow well in the intense heat of the south. White wonder cucumbers grow well outdoors when grown in zones 3 through 9, but also grow exceptionally well in greenhouse environments. 

Fertilizing

White wonder cucumbers require soil that is high very fertile throughout the entire growing season. Fertilize white wonder cucumbers at least once a month with a balanced fertilizer such as a 10-10-10. Amending the soil with compost or manure before planting can also help support strong, healthy growth. 

Harvesting White Wonder Cucumbers

White wonder cucumber fruits should be harvested once they are about 7 inches long, making them perfect plants for trellising. Fruits should begin to ripen 58 days after planting. Harvest cucumber fruits with a sharp blade regularly to promote abundant production before seed cavities swell. 

Growing from Seeds

Starting white wonder cucumbers seeds is not much different from growing regular cucumbers from seed. Being an heirloom plant, white wonder cucumbers will always produce seedlings as long as they are pollinated by other white wonder cucumbers. Note that if you plant multiple varieties of cucumbers close to one another, cross-pollination is likely.

White wonder cucumber seeds can be harvested directly from the cucumber or can be purchased at most nurseries and garden centers. If harvesting seeds directly from a cucumber fruit - scrape out the seeds, put them in a clear jar, and cover the seeds with water so that they float. Allow the seeds and their jelly coating to ferment for one to two days, or until the jelly coating has dissolved. Next, set the seeds out to dry. 

Seeds can be started indoors or sown directly into the garden with good success. However, cucumber plants do not tolerate cold well, so ensure that the last frost has passed before planting seeds or seedlings into the garden. Plant seeds 20 inches apart and about an inch deep.
