How Can You Grow Wave Petunias?

Grow wave petunias by choosing a good location, preparing the soil, planting the seedlings, watering and fertilizing. You need a spade, soil amendments, seedlings and fertilizer.

  1. Choose a location

    Plant wave petunias in an area that gets plenty of sunlight. The area should give the plants space to spread, such as on a hillside, on a retaining wall, in large planters in front of the house, or on the borders of fences or paths.

  2. Prepare the soil

    Amend the planting soil with manure, compost, peat moss or sand to make it nutrient-rich and well-draining. Spread amending material 2 to 3 inches thick, and use a spade to work it into the soil to a depth of about 6 inches.

  3. Plant the seedlings

    Plant the wave petunia seedlings 1 to 2 feet apart, because they spread quickly to create ground cover. When mature, they grow 4 to 6 inches high.

  4. Water and fertilize the plants

    Water the wave petunias regularly so that the soil remains moist. However, do not allow the soil to become soggy. Feed the plants with slow release fertilizer every 10 days to 2 weeks. Unlike most types of petunias, wave petunias do not need to be deadheaded. They produce abundant blooms continuously throughout the growing season.

  5. Watch for pests

    Get rid of aphids by hosing them off the plants. Watch for small holes in the leaves and buds that indicate budworm caterpillars. Although these pests disappear in early summer, use Bt pesticide if necessary.
