Fresh vegetables provide taste and nutrition to at-home gardeners. Despite these incentives, in today's busy world, not everyone has the time to devote to fussy, needy vegetables. However, there are a number of easily grown vegetable plants that even those without a green thumb can tackle in a home garden.
Radishes, Raphanus sativus, are among the quickest and easiest root crops to grow, according to "25 Vegetables Anyone Can Grow." These vegetables mature at a quick pace, usually between three and seven days, but this number may vary by the type of radish grown. Because of their quick growth time, they can be replanted for a number of harvests throughout the spring, summer and early autumn seasons. Radishes flourish in full sun and a slightly acidic soil. They grow easily in tilled soil, but are sometimes used to loosen the soil in lieu of tilling.
Lettuce, Lactuca sativa, is a leafy green vegetable that is a staple in salads. It thrives in light, sandy soil and cooler temperatures. Soil conditions should be rich and moist for optimal growth, according to the book "Grow Vegetables." Lettuce is best planted in full sun during early spring and late summer or fall, and in the shade during the hottest months of the year. Warmer temperatures and full sun can cause lettuce leaves to turn bitter to the taste. If the plants are not watered thoroughly on a regular basis, they may go to seed, a condition unfavorable to most home gardeners.
Carrots, Daucus carota, loosen the soil as they grow. A root crop that typically comes in orange, varieties are available in every color from white to dark purple. Carrots are hardy and may be planted as soon as the threat of frost has passed. Well-drained, loose loamy or sandy soils are recommended for optimal carrot growth. Plant carrots in an area with partial shade to full sun away from foot traffic. Sow carrots continually throughout the year with one or two weeks between each harvest, according to "Vegetable Gardening for Dummies."
The cucumber, Cucumis sativus, is a gourd closely related to the squash and zucchini. They grow best in hotter temperatures, between 65 and 75 degrees F, according to the Ohio State University Extension Office. Though they tolerate a variety of soils, they do best in loose, well-drained soil types. Cucumbers require a large amount of space, as they trail and climb as they grow. Despite this and their desire for nearly constant moisture, they are easily grown and harvested approximately 50 to 70 days after planting.
