  • Germination and days to maturity – based on seed packet. First frost date based on chart you will receive – at 67% for dates for U. Marlboro and LaPlata.

Transcript

  • 1. What is Fall Gardening?
    • Sucessional plantings of warm season crops for harvesting up to frost
    • 2. Late summer plantings of cool season crops that can tolerate a frost
    • 3. Fall plantings of very hardy crops for spring harvesting
    • 4. Protection of crops for extended harvest
  • Why plant in the fall?
    • Fewer harmful insects
    • 5. Fewer weeds
    • 6. Extended use of garden space
    • 7. Fresh crops for a longer time
  • Cool season crops
    Cole crops: broccoli, cabbage, collards, kale cauliflower, kohlrabi, Brussels sprouts
    Greens: leaf/head lettuce, spinach, chard, arugula, Asian greens, mustard, cilantro
    Root crops: rutabagas, beets, carrots, turnips, parsnips, radishes
  • 8. Overwintering Crops
  • Fall conditions
    • Cooler days and nights
    • 15. Shorter days
    • 16. Slower rate of crop maturation
    • 17. Some crops become sweeter
    • 18. Lettuce and spinach will not bolt
  • Transplants
    Transplants are commonly used for:
  • Setting out transplants
    • Seedlings need gradual exposure to direct sunlight
    • 23. Will benefit from light shading for the first few days
    • 24. Keep them moist!!
  • Direct seeding

  • 36. Timing of seeding for Fall Crops
    • Identify average first frost date
    • 37. Identify days to maturity from seed/transplant
    • 38. Add 14 days for Short Day Factor
    Days to plant before frost date =
    days to germinate/days to transplant +
    days to maturity + SDF
  • 39. Sample Calculation For Sowing Spinach Seeds
    Days to germination: 5-7
    Days to maturity: 35
    Short Day Factor (SDF): 14
    54-56 days
    Sow seeds about 8 weeks before the first frost (~Oct. 15)
    Mid August
  • 40. Row Cover Protection
    • Throw a bed sheet over row cover for a few days to provide shade.
    • 41. Row covers deter insects and larger critters.
    • 42. Row covers can extend season.
  • Organic mulches can provide shade and reduce evaporation
    ~ 1 month later
  • 43. Getting seeds to germinate in the late summer
    • Soil is often hot and dry in the late summer.
    • 44. Daily watering is often necessary to establish fall crops.
    • 45. Carrot seedlings will perish if soil is not kept moist.
  • Some seeds will not germinate at high temperatures.
    • The maximum soil temperature for germinating lettuce and spinach is 70-75 degrees F.
    • 46. For most vegetables, the optimum temperature for germination is 80 -90 degrees F.
  • Pre-germinating seeds
    • Soak seeds overnight in a moistened paper towel enclosed in a plastic bag.
    • 47. Do not soak longer than a day or 2 or delicate seedling parts will be damaged in planting.
  • Direct seeding in the fall
    • Plant seeds slightly deeper. Depth may be 1 ½ to 2 times deeper than spring.
    • 48. Can cover seeds in furrow with potting soil or vermiculite.
    • 49. Keep soil cool and moist. Cover seeded area with burlap, newspapers, or boards.
  • Water soil before sowing and after.
  • 50. Interplanting
    • Use shade from existing plants
    • 51. Sow lettuce, carrots, arugula, beets, collards
  • Mustard greens on north side of tomatoes
  • 52. What to do right now
    • Last plantings of fast growing warm season vegetables-snap beans, cukes, summer squash
    • 53. Start cabbage family seedlings indoors
    • 54. Direct seed carrots, beets, chard, kale, collards…
    • 55. Soak or pre-germinate lettuce or spinach seeds for direct seeding
  • Fall Planting Schedule
    10-12 weeks before frost:
    • Direct seed beets, carrots, collards lettuce, radishes…
  • Planting Schedule
    8 to 10 weeks before frost:
    • Direct seed Asian greens, arugula, turnips, spinach, mustard…
    • 56. Direct seed second planting of lettuce, radishes, beets…
    • 57. Set transplants for cabbage, broccoli, cauliflower…
  • Planting schedule
    6 to 8 weeks before frost:
    • Direct seed spinach, lettuce, arugula, radishes...
    • 58. Sow vegetables under protective cover.
  • Season extension
    Floating Row Cover
    Provides 4-10 degrees of protection
    Cold Frame
    Hoop House
    Greenhouse
