Flower Garden - Tips on Growing Coleus From Seeds
Additional Information:
Water plants on an as-needed basis. Coleus are sun tolerant but are suited best for partial sun. Tolerant of heat and humidity. Low maintenance, and plants will stretch under low lights. Space plants 12-14 inches apart in well-drained soil. Sow indoors 6-8 weeks before last frost.
DIRECT SOW After all danger of frost is over.
Stage 1 Radicle (Embryonic Root)
- Moisten the media before sowing the seed. If the media is watered after sowing, make sure seeds are not washed away.
- Light is beneficial during germination, or cover very lightly with vermiculite.
- Germination takes approximately 4-5 days. Keep media evenly moist but not saturated.
- Maintain 95% relative humidity until radicles emerge. Coleus is very sensitive to high salts, especially high ammonium during germination. Keep ammonium levels less than 10ppm.
- Germination: 72 -75�F (22 to 24�C)
Stage 2 Hypocotyl (Stem and cotyledon emergence)
- At stage 2 reduce soil moisture slightly to allow the roots to penetrate into the media. At stage 3 allow media to dry further until the surface becomes light brown before watering but avoid excessive wilting to promote root growth and control shoot growth.
- Stage 2: Days=72-75�F (21 to 24�C) Nights=60-65�F (16 to 18�C)
Stage 3 Cotyledon (Growth and development of true leaves).
- Coleus are low to moderate feeders, excessive feed can lead to dull coloration and decreased vigor. Apply fertilizer at rate 2 (100 to 175ppm ,predominately nitrate form with low phosphorus and high potassium.
- Stage 3: Days=60-62�F (16 to 17�C) Nights=55-60�F (13 to 15�C)
Stage 4 Getting ready for transplant/growing on period.
- Stage 4-Growing on stage-= Days=65-75�F , (18o 24�C) Nights=57-65�F �F (14to 18�C)
