Planting Celosia: Start 6-8 weeks before last frost. Lightly cover seed and keep warm (24 degrees C). Can be prone to damping off, keep soil on the dry side and water from below. Has poor frost tolerance so transplant outside about 2 weeks after last frost. Enjoys full sun and tolerates hot, dry areas.
Planting Geraniums: Start inside at least 12 weeks before last spring frost. Cover seed lightly and then provide constant warmth (70-75 degrees F) and moisture. Bottom heat is essential. (Except for inchesBlack Velvet Rose inches, which should be germinated cool, without bottom heat, at 60 F.) Cover to provide total darkness until germination occurs, in 5-15 days. Thereafter provide lots of light. Plant outside after last frost, 8-12 inches apart. Prefers full sun, but will tolerate light shade. Deadhead and remove yellowed leaves. Do not overfertilize.
Planting Petunias: 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.
Planting Sunflowers: Direct seed outdoors after all danger of frost is past. (Dwarf varieties can be seeded inside in peat pots 3 weeks before planting out.) Sow 1” deep in light, well-drained soil. Keep moist until seed germinates in 10-14 days. Space in a full sun location 6-24” apart depending on variety. Giant varieties should be planted 20-24” apart, while cut flower varieties should be spaced 6-10” apart to get smaller heads and slender stems for bouquets. Water regularly but do not over fertilize. Cut flowers last 10-14 days.
