Shock Wave® Red Spreading Petunia

Shock Wave® Red is the original PAS782803 petunia selection, with a mounded, spreading habit and crimson-red flowers. It is a useful choice for baskets and containers where its branching growth can cascade over the edge. ## Flowering and placement The selection is described as flowering from late spring until frost, with petite, early blooms that keep a bright red display through the season. Use it in a sunny mixed planting or in a basket where the flowers can be seen from below; allow room for the plant to spread rather than crowding it against upright neighbours. The [original Shock Wave Red profile](https://www.gardenia.net/plant/petunia-shock-wave-red) identifies this selection as PAS782803 and describes its flower color, habit, long flowering season, and container use. ## Growing conditions Grow petunias in full sun to part shade in moderately fertile, humus-rich, moist, well-drained soil. In a container, check the compost regularly in warm weather and water enough to keep the root zone from drying out. The [RHS container-watering study](https://www.rhs.org.uk/science/gardening-in-a-changing-world/water-use-in-gardens/watering-containers) found that bedding petunias performed well with modest, regular watering and that overwatering reduced plant quality. ## Maintenance Remove faded flowers as needed to keep the display tidy. Check baskets and pots often during hot weather, and water the compost rather than allowing the container to remain waterlogged.
