A mulching cultivation is useful for protecting plants from diseases and insects, for preventing the growth of weeds, and for keeping higher soil temperatures and moisture. Therefore, by using mulch, increases in crop yields may be expected even without the use of agricultural pesticides. In this study, the effects of various colored mulches on the growth of weeds, and also on the growth, yield and tannin content of Geranium thunbergii were studied. The mulches used in this experiment were transport, double, black and red mulches. Control plants were cultivated without any mulch. The results showed that the use of a double mulch or a black mulch prevented weeds from growing, but the use of a transport mulch encouraged their growth. The viability of G. thunbergii was higher when a double mulch was used, and the growth and yield of the plant increased when a double mulch or a red mulch was used. In the plants cultivated with a black mulch, the tannin content was higher, though the growth and yield were lower.
