Oppositeleaf Russian thistle performs best with abundant sunlight, which encourages vigorous growth. Native to sun-rich habitats, it is adapted to those conditions. Although it can tolerate periods of reduced light without suffering light-related harm, steady exposure to strong illumination supports its optimal development.

Oppositeleaf russian thistle prefers moderate temperatures, similar to those most people find comfortable. It grows best in conditions that are neither too hot nor too cold. The primary concern with high heat is sunburn, so giving it some shade in summer is recommended to avoid excessive warmth. When temperatures fall, Oppositeleaf russian thistle goes dormant. If continuous growth is wanted, warmer conditions must be maintained in winter. Frost can damage the plant and should be avoided.

To achieve maximum yield, Oppositeleaf russian thistle benefits from regular applications of a balanced fertilizer, especially one high in nitrogen. Apply fertilizer before planting, at planting, and when seedlings are 2 inches tall. Adding compost or manure also provides a steady supply of nutrients. Insufficient soil nutrients cause underdeveloped leaves and stems, poorer flavors, thin stems, and possibly a bitter taste.
