  1. Bedding Plant Production Competencies: 10.00-13.00

  2. Flowering Annuals • Easy to grow • Lend color to landscapes a short time after they are planted • Usually started from seed indoors early in the spring

  3. Provide mass color Fill in spaces between shrubs or other perennials Provide color in bulb beds after bulbs have bloomed Supply cut flowers Plant along fences or walks Cover bare spots between or in front of shrubs Create seasonal color Flowering Annuals Used to:

  4. Deciding which to grow: • Height • Spacing • Color • Uses

  5. Procedure • Decide which annuals to grow. Outline plan in writing. • Seed 6-8 weeks prior to outside planting date (First-Frost-Free Day) • Prepare soil well ahead of time • Plant according to plan after FFFD • Water, weed, and mulch as needed • Pinch off all faded blooms • Provide insect control • ENJOY!

  6. Caring for the plants: • Water if the soil becomes too dry • Pull weeds or mulch for weed control • Remove all faded blossoms • If necessary spray with malathion or Sevin depending on insect control • Fertilize as needed to keep plants growing actively

  7. Begonias Geraniums Impatiens Marigolds Pansies Petunias Potential Problems Media Transplanting Bedding Plant Production Categories (Click to view)

  8. Begonias • Grow 6”-12” high with pink, red, or white flowers • Spaced 6”-10” apart and need direct sunlight • May be propagated from seeds or cuttings and transplanted

  9. Begonias • Time from seeding to market in packs is about 14 weeks (16 weeks in pots) • Small seeds should be lightly pressed into surface of germinating medium • Germination requires light and 65-70 degree F medium temperature • Can be propagated by stem cuttings • Plants do well in full sun to shade

  10. Geraniums • Grow 12”-18” • Dark green leaves are rounded with scalloped edges • Flowers are red, white, or pink and grow on a stem • Flowers have many petals in a cluster shaped like a ball

  11. Geraniums • About 2/3 of all geraniums sold are red • Direct sunlight is needed • 10”-12” spacing is needed • May be propagated from seeds or cuttings and transplanted

  12. Geraniums • Time from seeding to market in packs is about 14 weeks (16 weeks in pots) • Seeds are large and have to be scarified because of hard seed coats • Seed suppliers usually scarify before packing for sale. Seeds should be coved with 1/8 inch of medium • Medium should be about 75 degrees F.

  13. Impatiens • Grow 6”-18” high and have succulent stems • Lance shaped leaves • Flower colors include pink, lavender, white, red, purple, salmon, and coral.

  14. 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 cuttings

  15. 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

  16. 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 transplanted

  17. 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

  18. 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 plant

  19. 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

  20. 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 transplanted

  21. 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

  22. 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

  23. Cultural-Germination Problems • Causes • Improper temperatures • Over-watering or underwatering • Chemical residues in medium • Seed planting depth • Low quality seeds

  24. 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 levels

  25. Cultural-Fertilization Problems • Causes • Lack of nutrients • Root injury • Improper pH of medium • Excessive fertilization Manganese Deficiency

  26. Cultural-Fertilization Problems • Correction or Prevention • Test soil or media • Apply correct amounts and kinds of nutrients • Use pH correcting materials

  27. Cultural-Uneven Growth • Causes • Poor mixing of medium • Uneven moisture levels • Unlevel flats • Poor grading of seedlings

  28. Cultural-Uneven Growth • Correction or Prevention • Proper mixing of media • Even watering • Grading seedlings by size and quality • Placing flats level

  29. Cultural-Tall and Spindly Growth • Causes • Too much nitrogen fertilizer • Overwatering • Low light intensity (too much shade) • High temperatures

  30. 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

  31. Diseases-Seedlings Falling Over • Causes • Stem rot • Damping-off

  32. Diseases-Seedlings Falling Over • Correction or Prevention • Use sterilized media • Apply fungicides • Improve air circulation around plants

  33. Diseases-Brown, rotting leaves • Causes • Botrytis

  34. Diseases-Brown, rotting leaves • Correction or Prevention • Increase air temperature • Increase air circulation around plants • Use proper fungicide

  35. Insects-Plants Missing • Causes • Slugs • Snails • Cockroaches

  36. Insects-Plants Missing • Correction or Prevention • Use baits and pesticides

  37. Causes Aphids Mealy Bugs Scale Insects Thrips Whiteflies Flea beetles Fungus Gnats Leaf miners Cutworms Caterpillars Insects-Holes in Leaves

  38. Insects-Holes in Leaves • Correction or Prevention • Use of recommended pesticides to control insects

  39. Bedding Plant Media • Media-materials used to start and grow plants • Soil • Inorganic materials • Commercially prepared mixes

  40. Soil • Soil must be mixed with other materials such as peat moss to add organic matter and improve aeration and drainage.

  41. 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 • sterile

  42. Commercially Prepared Mixes • Sterile (no insects, weeds, or diseases) • Jiffy-Mix • Redi-Earth • Pro-Mix • Sunshine Mix • Metro Mix • Other brands also available

  43. 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 soil

  44. 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
