How to keep Amaranthus Cannabinus.
Light
Tidalmarsh amaranth is a sun-loving, perennial herbaceous plant that comes from open habitats and often thrives in meadows and grasslands. It prefers full sun but can also tolerate partial sun.
Water
Tidalmarsh amaranth flourishes in consistently moist environments, making wetlands its preferred habitat. Although it can tolerate moderate drought, weekly watering is ideal for maintaining its health. Providing abundant water during the growing season supports its vigorous growth and resilience.
Temperature
Tidalmarsh amaranth comes from tropical areas, where the climate is generally warm and humid. As a result, it is adapted to high temperatures and humidity. It dislikes abrupt temperature changes and prefers a stable thermal environment, so it is important to avoid temperature fluctuations indoors. It typically cannot tolerate cold conditions and requires warmer temperatures to grow. If the surrounding temperature falls too low, the plant may stop growing or even die.
Fertilizer
Tidalmarsh amaranth needs the most fertilizer during its active growing period, which is mainly in spring, summer, and early fall. Fertilization supplies essential nutrients that the soil may lack, supporting healthy root and stem growth and promoting the attractive foliage that is a key characteristic of this plant.
