cucumber is a creeping vine that roots in the ground
The cucumber is a creeping vine that roots in the ground and grows up trellises or other supporting frames, wrapping around ribbing with thin, spiraling tendrils.
The plant has large leaves that form a canopy over the fruit. The fruit of the cucumber is roughly cylindrical, elongated with tapered ends, and may be as large as 60 centimeters (24 in) long and 10 centimeters (3.9 in) in diameter.
Having an enclosed seed and developing from a flower, botanically speaking, cucumbers are classified as fruits. However, much like tomatoes and squash they are often perceived, prepared and eaten as vegetables.
Cucumbers are usually more than 90% water.
In human cultivation, the varieties of cucumbers are classified into three main varieties: "slicing", "pickling", and "burpless".
Slicing
Cucumbers which are grown to be eaten fresh are called slicers. The fruit of these cucumbers can grow up to 35 centimeters (14 in) long. They are mainly eaten in the unripe green form. The ripe yellow form normally becomes too bitter and sour. These cucumbers can also be harvested for pickling when they are smaller. Slicers grown commercially for the INDIA market are generally longer, smoother, more uniform in color, and have a much tougher skin. Slicers in other countries are smaller and have a thinner, more delicate skin.
Pickling
Cucumbers can be pickled for flavor and longer shelf-life. Although any cucumber can be pickled, commercial pickles are made from cucumbers specially bred for uniformity of length-to-diameter ratio and lack of voids in the flesh. Those cucumbers intended for pickling, called picklers, grow to about 7 centimeters (2.8 in) to 10 centimeters (3.9 in) long and 2.5 centimeters (0.98 in) wide. As compared to slicers, picklers tend to be shorter, thicker, less regularly shaped, and have bumpy skin with tiny white- or black-dotted spines. They are never waxed. Color can vary from creamy yellow to pale or dark green. Pickling cucumbers are sometimes sold fresh as “Kirby” or “Liberty” cucumbers. The pickling process removes or degrades much of the nutrient content, especially that of vitamin C. Pickled cucumbers are soaked in brine or a combination of vinegar and brine, although not vinegar alone, often along with various spices. Pickled cucumbers are often referred to simply as "pickles" in the United States or "Gherkins" or "Wallies" in the United Kingdom, the latter name being more common in the north of England where it refers to the large vinegar-pickled cucumbers commonly sold in fish & chip shops. (Although the gherkin is of the same species as the cucumber it is of a completely different cultivar.)
Burpless
BurplessSome varieties of cucumber are marketed as “Burpless”, because the seeds and skin of other varieties of cucumbers are said to give some people gas[citation needed]. The burpless variety is reputed to be easy to digest and have a pleasant taste.They can grow as long as 2 feet (0.61 m). They are nearly seedless, have a delicate skin which is pleasant to eat. Most commonly grown in greenhouses, these parthenocarpic cucumbers are often found in grocery markets shrink-wrapped in plastic.
How to Grow Cucumbers
Cucumbers hail from India, so it should come as no surprise that they crave warmth. In fact, they need it at every step of the growth cycle, from germination to fruiting.
Instructions
1
Choose a site with all-day sun, except in hot, dry regions, where cucumbers like some afternoon shade. Soil should have a pH of 6.0 to 7.0.
2
Dig deeply and enrich the soil with plenty of compost and well-rotted manure.
3
Sow cucumber seeds directly into the ground at least two weeks after the last frost and when both soil and air temperatures average at least 65 degrees F. Expect germination in 3 to 10 days, depending on soil temperature. (The higher the temperature, the faster the seeds will sprout.) Set vining varieties 2 to 3 feet apart; bush types, 18 inches apart.
4
Spray the plants with fish emulsion fertilizer about four weeks after germination, or side-dress with compost.
5
Mulch the soil once the plants are established to control weeds and conserve moisture.
6
Provide at least an inch of water each week, especially when the plants are flowering and fruiting.
7
Pick cucumbers when they're still moderate-sized - between 3 and 4 inches for pickling varieties and 6 to 8 inches for slicers - otherwise they'll become seedy and bitter. Cukes mature at the speed of light, so check your plants daily.
