Growing Cucumbers in the Home Garden

Cucumbers are a member of the Cucurbitaceae family, which includes squash and melons. There are two types of cucumbers that can be grown. There are slicing cucumbers and pickling cucumbers. They can be grown in a variety of shapes and sizes, from 1 inch long to greenhouse varieties that can reach 20 inches or longer.

Cucumbers are a summer crop and are very sensitive to cold. The seed will not germinate until the soil temperature reaches at least 60 degrees F. Seeds can be started indoors and transplanted at least two weeks after the last frost. Seedlings or seeds can be planted  at least 12 inches apart and then thinned to desired in-row spacing. If space is limited use a trellis. Trellising often provides a higher yield and improved fruit quality.

Full sun and a well drained loamy soil is preferred. Cucumbers like to be grown in a a soil with a pH of 6.0. It is best to do a soil sample as with all vegetables to determine the soils needs. Cucumbers are heavy feeders and require fertilization routinely for them to continue to produce. It generally takes about six weeks from seed to picking. If you keep the cucumbers picked every couple of days and remove the bad ones they will continue to flower and produce cucumbers for up to four to six weeks. Pollination is also important to have high yields.

Did you know that English cucumbers are called “burpless” because their lack of seeds eliminate gas buildup. Generally smaller cucumbers contain fewer and smaller seeds. Popular slicing varieties include Straight 8, Poinsett, Tasty Green and Gemini. Some popular pickling varieties include Gershwin, Supremo, Citadel and Calypso.

Did you know that the inner temperature of a cucumber can be up to 20 degrees cooler than the outside air due to its water content of almost 96%. When harvesting a dark green cucumber be sure to store it at 50-55 degree F and 85-95% relative humidity. If cucumbers remain in high temperatures they tend to ripen quickly and turn yellow. Cucumbers if stored properly can last for at least a week.
