Planting & Growing

Yellow Sweet Spanish Onion will grow to be about 12 inches tall at maturity, with a spread of 4 inches. When planted in rows, individual plants should be spaced approximately 4 inches apart. This vegetable plant is an annual, which means that it will grow for one season in your garden and then die after producing a crop. As this plant tends to go dormant in summer, it is best interplanted with late-season bloomers to hide the dying foliage.

This plant is typically grown in a designated vegetable garden. It should only be grown in full sunlight. It does best in average to evenly moist conditions, but will not tolerate standing water. It is not particular as to soil type or pH. It is highly tolerant of urban pollution and will even thrive in inner city environments. This is a selected variety of a species not originally from North America, and it is considered by many to be an heirloom variety. It can be propagated by multiplication of the underground bulbs; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.
