Proper preparation of the soil goes a long way in getting the most from pansy plants. Work in organic material such as compost or well rotted leaves to a 4-inch (10 cm.) depth before planting pansies.
When growing pansies in well-prepared soil, the need for fertilization will be minimal. Pansies also prefer acidic soil, so do not add limestone unless indicated by a soil test. Other pansy care is simple; water and deadhead pansies for a longer period of blooms
