Effects of rice husk charcoal on the pH of culture medium and plant growth in container culture were investigated. Culture mediums were prepared with soil, compost and rice husk charcoal at different ratios. Gerbera was grown as the test plant. Experimental results showed that the growth of plant was hastened by using 25-33% of rice husk charcoal together with 17-25% of compost in culture mediums. Acid soil could be improved with rice husk charcoal. However, the culture medium containing 80% rice husk charcoal had a pH of 7.4, which slowed the growth of plant. It was found that the number of leaves, and the dry matter of plant increased exponentially with plant height, respectively
