Radishes are one of the fastest vegetables to grow, taking just 3-4 weeks. Seeds can be sown into prepared ground or pots of potting soil. Make sure you sow the seeds very thinly, spacing them about 2.5cm apart.
The fastest growing spring vegetables include the following: radishes, lettuce, spinach, arugula, kale, turnips, and peas. All of these vegetables should be fertilized, planted in loose soil, and given adequate sun and moisture. None require pruning and all can be grown in mostly any zone.

1: Artichoke
Due to similar climate conditions, artichokes work well as perennials in northern California, but may be difficult to grow as perennials in other areas of the nation. Since artichokes like moderate conditions, grow them as annuals in cold winter and hot summer areas.
Cucumbers are ready for harvest 50 to 70 days from planting, depending on the variety. Depending on their use, harvest on the basis of size. Cucumbers taste best when harvested in the immature stage (Figure 2). Cucumbers should not be allowed to reach the yellowish stage as they become bitter with size.
Depending on the variety—early-, mid-, or late-season—and local weather conditions, Tomatoes take 50 to more than 80 days to grow from seedling to harvest.
