Shock Wave Petunia Seed Collection
This collection contains 3 seed Pkgs, 1 each of Denim, Coral Crush and Volt Mix Shock Wave Petunias.
Petunia hybrida. Petite 1½-2 inch flowers closely resemble Calibrachoa with the spreading habit of Wave petunias! They will ‘shock’ you with their vigour and you only need one plant in a 12” container to fill it to over flowing so no need to plant many for a big impact! The first petunias to flower, self-cleaning and prolific, Shock Waves are a pleasure to grow! Height 8-10".
Start inside 8 weeks before last frost. Sprinkle the tiny seed onto soil surface and gently press them in; do not cover. Provide light and constant warmth (21-24 degrees C). Use a bottom heat source for best results. Transplant after last frost into a full sun location. 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 to 18 inches apart in beds, or place 1 to 3 plants in each 10 inches 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.
