The Versatile Little Leaf Cucumber

Cucumbers are a delightful addition to any garden. These warm-season vegetables belong to the Cucurbitaceae family, alongside melons, summer squash, winter squash, and gourds. Their diverse shapes, sizes, and uses make them a versatile and popular choice for home growers and commercial farmers alike.

A World of Variety

Cucumbers come in various forms, each with its own unique characteristics. From small and spiny picklers that are ideal for preservation to European slicers with thin, tender skin, there’s a cucumber for every taste. American slicers, on the other hand, have a thicker skin, making them sturdier and perfect for shipping. For those seeking something truly out of the ordinary, specialty cucumbers come in all kinds of shapes, from little spheres to long, skinny, curly types, available in both gold and green.

Nutrient-Rich Soil

To thrive, cucumbers require well-drained, fertile soil with a neutral pH and plenty of organic matter. They are known to be heavy feeders, so it’s crucial to provide them with proper nutrition. Sidedressing is recommended one week after blossoming and again three weeks later, especially if any signs of nutrient deficiency appear. Keep an eye out for yellowing leaves, which may indicate a lack of nitrogen, and bronze leaves, which may signify a potassium deficiency.

Planting Depth and Spacing

When planting cucumber seeds, a depth of half an inch is ideal. As for plant spacing, slicing cucumbers should be placed 12-24 inches apart, pickling cucumbers require 8-12 inches of space, and greenhouse cucumbers need around 20 inches. For row spacing, slicing and greenhouse cucumbers should be set at 5-6 feet apart, while pickling cucumbers require a spacing of 3-6 feet.

Perfect Timing

Cucumbers can either be directly seeded or transplanted. However, it’s best to wait until all danger of frost has passed before doing so. Transplants should be started 3-4 weeks before the planting date. For successful germination, the optimal soil temperature is around 85°F. If the soil temperature drops below 50°F, it may slow down growth and hinder water uptake by the roots. Cucumbers thrive in an air temperature of at least 70°F during the day and 60°F at night. To ensure the right conditions for field cucumbers, many growers use plastic mulch and row covers, which increase soil and air temperature while protecting them from insects. However, it’s important to remove the row covers once the plants begin to flower to facilitate pollination.

Additional Considerations

Greenhouse cucumbers have a slightly different cultivation process. They should be pruned to one central leader and trellised with a sliding wire system that adjusts as the vines grow. These cucumbers are parthenocarpic, meaning they can produce fruit without the need for pollination. To achieve seedless cucumbers, it’s crucial to exclude insects from the greenhouse, as they can inadvertently pollinate the flowers, resulting in seeded fruit. Keep in mind that cucumbers can sometimes grow misshapen due to low fertility or poor pollination.

Harvesting and Storage

Once cucumber plants begin to bear fruit, it’s essential to harvest every day or two to ensure continuous production. Overripe fruit left on the plants can slow down the overall harvest. When it comes to storage, cucumbers can be stored for up to 7-10 days at temperatures between 50-55°F, with a relative humidity of 95%. However, it’s important to note that temperatures lower than 50°F can cause injury to the cucumbers. Thin-skinned varieties are best stored when wrapped in plastic.

Pest and Disease Management

Just like any other plant, cucumbers are susceptible to pests and diseases. Striped or Spotted Cucumber Beetles, for example, can cause significant damage. It’s advisable to protect young plants with floating row covers, rotate crops, and remove debris to discourage overwintering populations. Squash Vine Borers also pose a threat, especially in late June to early July. These pests lay eggs at the base of stems, which the larvae then chew through, causing wilting. Keeping the area clean and destroying crop residues can help control their population.

Aphids, another common cucumber pest, can be washed off plants with a strong jet of water. Many natural predators, such as lady beetle larvae and lacewings, help control aphid populations.

When it comes to diseases, cucumber plants can fall victim to various types, including bacterial wilt, angular leaf spot, gummy stem blight, cucumber mosaic virus, and scab. To prevent these diseases, it’s essential to use row covers to exclude aphids, control weeds, select disease-resistant varieties, and ensure proper plant spacing to allow for adequate air circulation.
