Planting & Growing

Garnet Red Mustard will grow to be about 16 inches tall at maturity, with a spread of 8 inches. When planted in rows, individual plants should be spaced approximately 10 inches apart. This fast-growing vegetable plant is an annual, which means that it will grow for one season in your garden and then die after producing a crop. Because of its relatively short time to maturity, it lends itself to a series of successive plantings each staggered by a week or two; this will prolong the effective harvest period.

This plant is typically grown in a designated vegetable garden. It does best in full sun to partial shade. It does best in average to evenly moist conditions, but will not tolerate standing water. It is not particular as to soil pH, but grows best in rich soils. It is somewhat tolerant of urban pollution. This is a selected variety of a species not originally from North America.

Garnet Red Mustard 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.
