How to Grow Celosia Kosmo Mix from Seed
Step 1: Sowing Indoors
-
Use a sterile seed starting mix.
-
Sow pelleted seeds on the soil surface and press lightly (they need light to germinate).
-
Maintain a consistent 72–75°F (22–24°C) soil temperature.
-
Keep evenly moist but not soggy (moisture level 4–5).
-
Seeds typically germinate in 5–7 days.
Step 2: Transplanting
-
Transplant seedlings once they form two sets of true leaves.
-
Move to cell packs or pots for strong root development.
-
Harden off before planting outdoors.
Step 3: Outdoor Planting
-
Sunlight: Requires full sun (6–8 hours daily).
-
Soil: Fertile, well-drained with pH 5.5–6.5.
-
Spacing: 8–10 inches apart for bushy growth.
-
Watering: Maintain even moisture, but avoid overwatering.
Step 4: Fertilization
-
Apply a balanced fertilizer every 1–2 weeks at 100–150 ppm nitrogen.
-
Do not over-fertilize; too much nitrogen will encourage leaves over flowers.
Kosmo Mix for Cut Flowers
