Grow Stunning Petunias: 8 Tips for Balcony Pots and Long-Lasting Blooms

  • Petunias, known as the “fireworks of the flower world,” thrive in pots and hanging baskets, adding vibrant color to balconies.
  • They require at least six hours of direct sunlight daily; place pots in the sunniest spot for optimal blooming and to prevent lanky growth.
  • Water deeply when the topsoil is dry, ensuring good drainage, as petunias dislike soggy feet; daily watering may be needed in hot weather.
  • Petunias are heavy feeders; fertilize every couple of weeks with a balanced liquid or slow-release fertilizer to maintain lush, colorful blooms.
  • Deadhead spent flowers and trim leggy stems to encourage more blooms and bushier growth, preventing a droopy appearance.
