Petunia
Petunia x hybrida
Starting:
Use a peat based soilless mix that contains perlite or vermiculite for drainage. Handle the plug by the root ball, never by the stem. Place the plant in the center of the pot and at the same depth at which it is already growing. Gently firm the soil around the new plant and water in well.
Growing:
Wave petunias need full sun (at least 6 hours daily) exposure and well-drained, fertile soil. Provide plenty of water and regular fertilizer for peak performance. Space plants 12-18 inches apart in beds, or place 1-3 plants in each 10-inch container. With the Tidal Wave Petunias, 12 inch spacing forces the plants to grow 2 feet tall, while wider spacing allows the plants to grow shorter and spread. Feed plants every 2 weeks with a complete plant food, such as 10-20-10 or an organic alternative, to maintain constant flowering. Pinch back errant, long stems to encourage bushier growth.
