We may live in society that stresses equality between men and women, but when it comes to gardening, women seem to have an upper hand because of their larynx. You see, sound waves are an environmental effect just like rain or light.
An experiment by my Horticultural Class in 1987, found plants grow faster when they were sang to. The sung-to plants grew two inches higher than their unsung-to counterparts. Female student voices worked especially well for faster growth. Male student voices, couldn’t make the plants grow as quickly, and in some cases, low-voiced males stunted the growth of the plants by singing at them. This must be why we throw rotten tomatoes at horrible singers.
