Seeds should be coved with 1/8 inch of medium Medium should be about 75 degrees F. Impatiens: Impatiens Grow 6”-18” high and have succulent stems Lance shaped leaves Flower colors include pink, lavender, white, red, purple, salmon, and coral.Impatiens: Impatiens Flowers are small and round with five petals One flower petal is shaped like a tube that protrudes from the underside of the flower Spaced 12”-18” and needs partial sun or shade May be propagated from seeds or cuttingsImpatiens: Impatiens Time from seeding to market in packs is about 8 weeks Seeds should be placed on surface of medium and covered lightly Germination requires light and temperature of 60-70 degrees F Have been the number one bedding crop for many years Grow well in shade Marigolds: Marigolds Grow from 6” to 4’ tall Orange or yellow flowers have a pungent aroma Spaced 6”-12” apart and grow best in full sunlight Grown from seeds and transplantedMarigolds: Marigolds Time from seeding to market in packs is about 9 weeks (10 weeks in pots) Seeds should be covered by ¼” of germinating medium Medium should be 70-75 degrees F Outdoor plants should grow in full sun for best quality Very few cultural problems Pansies: Pansies Grow from 6-8” tall Moon-faced flowers in many colors (blue, purple, yellow, white, pink, red) Spaced 6-8” in full sun Grown from seeds and transplanted Cool-season bedding plantPansies: Pansies Time from seeding to market in packs is about 12 weeks (13 weeks in pots) Seeds should be planted on surface of medium and covered with paper to keep dark Germination medium should be 70 degrees Fahrenheit Grow in full sun Petunias: Petunias Grow from 6”-18” tall Flowers have a tube-shaped base Colors include red, pink, white, blue, and pastels Spaced 10”-12” Grown from seeds and transplantedPetunias: Petunias Time from seeding to market in packs is about 10 weeks (11 weeks in pots) Sow seeds on surface of medium Seeds are very small (285,000 per ounce) Need light and 70-80 degrees F germinating medium temperature Many different types and colors One of top five annuals in the U.S. for over 100 years Potential Problems (Click to view): Potential Problems (Click to view) Cultural Disorders Germination Problems Fertilization Problems Uneven growth Tall and spindly growth Diseases Seedlings falling over Lower leaves brown, rotting, and drying Insects Plants missing Holes in leaves or plant parts missing Cultural-Germination Problems: Cultural-Germination Problems Causes Improper temperatures Over-watering or underwatering Chemical residues in medium Seed planting depth Low quality seedsCultural-Germination Problems: Cultural-Germination Problems Correction or Prevention Use high-quality seeds Plant at proper depth Use medium with no chemical residues Maintain proper temperatures Maintain proper moisture levelsCultural-Fertilization Problems: Cultural-Fertilization Problems Causes Lack of nutrients Root injury Improper pH of medium Excessive fertilization Manganese DeficiencyCultural-Fertilization Problems: Cultural-Fertilization Problems Correction or Prevention Test soil or media Apply correct amounts and kinds of nutrients Use pH correcting materialsCultural-Uneven Growth: Cultural-Uneven Growth Causes Poor mixing of medium Uneven moisture levels Unlevel flats Poor grading of seedlingsCultural-Uneven Growth: Cultural-Uneven Growth Correction or Prevention Proper mixing of media Even watering Grading seedlings by size and quality Placing flats levelCultural-Tall and Spindly Growth: Cultural-Tall and Spindly Growth Causes Too much nitrogen fertilizer Overwatering Low light intensity (too much shade) High temperaturesCultural-Tall and Spindly Growth: Cultural-Tall and Spindly Growth Correction or Prevention Use the correct amount of nitrogen Reduce frequency of watering Lower temperature Provide more light Use growth retardant such as B-Nine SP Diseases-Seedlings Falling Over: Diseases-Seedlings Falling Over Causes Stem rot Damping-offDiseases-Seedlings Falling Over: Diseases-Seedlings Falling Over Correction or Prevention Use sterilized media Apply fungicides Improve air circulation around plantsDiseases-Brown, rotting leaves: Diseases-Brown, rotting leaves Causes BotrytisDiseases-Brown, rotting leaves: Diseases-Brown, rotting leaves Correction or Prevention Increase air temperature Increase air circulation around plants Use proper fungicide Insects-Plants Missing: Insects-Plants Missing Causes Slugs Snails CockroachesInsects-Plants Missing: Insects-Plants Missing Correction or Prevention Use baits and pesticidesInsects-Holes in Leaves: Insects-Holes in Leaves Causes Aphids Mealy Bugs Scale Insects Thrips Whiteflies Flea beetles Fungus Gnats Leaf miners Cutworms CaterpillarsInsects-Holes in Leaves: Insects-Holes in Leaves Correction or Prevention Use of recommended pesticides to control insects Bedding Plant Media: Bedding Plant Media Media-materials used to start and grow plants Soil Inorganic materials Commercially prepared mixesSoil: Soil Soil must be mixed with other materials such as peat moss to add organic matter and improve aeration and drainage.Inorganic Materials: Inorganic Materials Improve aeration and drainage Sand-finely ground stone Gravel Perlite Expanded volcanic rock Neutral pH 7.0-7.5 sterile Vermiculite Expanded mica sterileCommercially Prepared Mixes: Commercially Prepared Mixes Sterile (no insects, weeds, or diseases) Jiffy-Mix Redi-Earth Pro-Mix Sunshine Mix Metro Mix Other brands also availableContainers: Containers Flat-plastic tray used for planting seeds Cell packs-several small cell-like pots of plastic molded together used for planting one or two seeds per cell Sold without transplanting to another container Peat pots can be planted directly in the soil Jiffy 7 pellet can be planted directly in the soilContainers: Containers Plastic pots of various sizes and shapes Clay pots of various sizes and shapes Styrofoam pots of various sizes Hanging baskets Standard pot is the same width at the top as it is high Azalea pot is ¾ as high as its top diameter or width Transplanting Instructions: Transplanting Instructions Seedlings should have true leaves not just seed leaves or cotyledons before being transplanted. Waiting too long to transplant causes shock to transplanted seedlings.Transplanting Instructions: Transplanting Instructions Hold plants by their leaves. Do not hold by the stem because a badly bruised stem will cause the seedling to die. The media may need to be loosened with a pot label to keep from breaking stem and roots. Do not shake medium off roots.Transplanting Instructions: Transplanting Instructions Use a dibble or other means to make a hole for the transplanting seedling.Transplanting Instructions: Transplanting Instructions 5. Plant seedling in the media in the new container slightly deeper than it grew in the flat and gently press media around roots.Transplanting Instructions: Transplanting Instructions 6. Water gently to settle media around roots.Transplanting Instructions: Transplanting Instructions Keep moist for a few days to prevent wilting and dying. Grow and harden-off before selling.
