Petunia Seed Collection
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.
Will tolerate light shade but blooming will be reduced. Petunia Spacing: Fantasy Mix 6-8 inches; Colorama, Prism, Celebrity and Double Cascade 8-10 inches.
Must be deadheaded regularly. Do not overwater or overfertilize. Use a low-nitrogen/high-phosphorus fertilizer sparingly.
