Planting & Growing
Ruby Red Onion will grow to be about 18 inches tall at maturity, with a spread of 4 inches. When planted in rows, individual plants should be spaced approximately 6 inches apart. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 1 years.
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. This plant is a heavy feeder that requires frequent fertilizing throughout the growing season to perform at its best. 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.
Ruby Red Onion is a good choice for the vegetable garden, but it is also well-suited for use in outdoor pots and containers. It is often used as a 'filler' in the 'spiller-thriller-filler' container combination, providing the canvas against which the larger thriller plants stand out. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
