When should I water and fertilize my Wave Petunias?
Don't let your Wave Petunias dry out between waterings. They need plenty of water, but keep in mind that the soil in beds and containers must be well-drained and containers dry out faster than in-ground beds. If possible, water your plants in the morning so the foliage dries before evening.

Wave Petunias are heavy "feeders." The full potential of Wave Petunias will not be realized from hungry plants. Apply a liquid fertilizer every 10 to 14 days or use a combination of liquid and a slow-release fertilizer. Always follow the recommendations shown on the labels!
