  • Good quality soil is needed, too hard soil will not become airy for other plants.
  • Fertilize the soil well to maintain the level of nutrients in the soil as the demand is more for companion planting. 
  • Watering should be done regularly for both the plants just like the pansies plants in the container as the soil dries out even more quickly.
