For newly planted cacti, no fertilizer should be applied in the first year.
Main value of cacti
The stomata of cacti close during the day and open at night, absorbing carbon dioxide and releasing oxygen, which can improve indoor air quality and purify the air. Moreover, the plants can absorb gases such as sulfur dioxide, hydrochloric acid, carbon monoxide, and nitrogen oxides.
