  • 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
