Beyond providing them with adequate fertilization, there are some care tips that can help you ensure that your petunias are always full of flowers, take good note:

  • Sunny location. Make sure they receive 6 to 8 hours of direct sunlight each day and you will achieve healthy and vigorous flowering.
  • Good drainage. Choose pots or soil with good drainage capacity for them, because an accumulation of water in the roots inhibits flowering.
  • Regular watering. Keep its soil evenly moist, but not soggy.
  • Removal of flowers. Remove any flowers that are already wilted. This “dead pruning” stimulates the appearance of new flowers, because it allows the plant to focus on flowering instead of generating seeds.
  • Light pruning. When the plant starts to look untidy, do some light pruning. This promotes more compact growth and encourages branching, and the more branches your petunias have, the more flowers they will produce.
  • Aeration and space. Leave enough space between your plants so that air can circulate. This reduces the risk of fungus and promotes healthy growth.

By following these tips and applying fertilizers for petunias correctly, you will make these small plants look spectacular and fill your house with color with their flowers.
