CARE GUIDE

How to keep Spirobassia Hirsuta.

Light

Hairy smotherweed is native to bright, open areas and grows best in full sun. It can tolerate partial sun but prefers direct sunlight for optimal growth. This plant, which may be annual or biennial, is known for its sun-loving habit.

Temperature

Hairy smotherweed can tolerate a wide range of temperatures, but its distribution can still be restricted by different combinations of moisture and heat. It performs best in warm summer climates when there is enough rainfall or supplemental watering. Long periods of cloudy, rainy weather or sustained high temperatures increase the risk of Hairy smotherweed dying. In winter, protecting it from cold conditions can improve its survival chances.

Fertilizer

Hairy smotherweed benefits from regular, light applications of fertilizer to encourage healthy leaf growth. Fertilize hairy smotherweed about once a month during the summer months. Nitrogen is important for foliage, and adding nitrogen-rich sources helps hairy smotherweed thrive.
