    Starting Seeds Indoors by Chris Turse Rooting Dc Starting Seeds Indoors by Chris Turse Rooting Dc Presentation Transcript

    • Starting Seeds Indoors
    • Mendell and His Peas…
      • C ontain s genetic material
      • Heirloom
      • Open-pollinated vs. hybrid
      • Seed saving
    • Fertilization
      • W hen a male pollen cell (sperm cell) forms a union with a female egg cell (ovum), a seed is formed
    • Seed Anatomy
      • Three main parts
        • embryo
          • young plant
        • seed coat
          • protects
        • seed leaves (cotyledons)
          • food reserve
    • Seeds!
      • 4-18% water
      • Smallest seed?
      • The largest seed?
    • Seed Selection
      • USDA Zone 7
      • E arly frost (around October 10 th )
      • Late frost (around May 10 th )
      • Annual
      • Biennial
      • Perennial
      • Season extension
    • Seed Selection
      • T rustworthy dealer
      • R ead information in seed catalogs and on seed packets
    • Germination
      • M ature seed: right environment
        • stratification
        • scarification
      • KEYS: water, oxygen, and temperature
    • Seed Storage
      • Leftovers?
        • K eep inside packet, place into a plastic bag, and then into a refrigerator
        • T ime of storage is variable
    • Planting Media
      • T wo groups: soilless media and amended soil mixes
      • S oil l ess media is generally used to start seeds
      • A mended soil mixes generally used to transplant
    • Soilless Media
      • S phagnum moss, pumice, peat moss,vermiculite, perlite, sand, pine bark, coconut fiber , good compost!
      • Environmental concerns
      • Key: fine and uniform yet well aerated and loose
      • Oxygen!
    • Amended Soil Mix
      • T ransplanting
      • C ontain s compost and/or a mixture of organic plant nutrients  
      • M ix your own or buy pre-mix
      • Oxygen!
    • Sterile Soil
      • N o insects, disease organisms, or weed seeds
      • C ompost contains benefical micro-organisms and may help fight disease
    • Re-using Soil?
      • ‘ T reat ’ the soil in an oven to sterilize it  
      • 250 degrees Fahrenheit
      • C ook soil at an internal temperature of 180 degrees Fahrenheit for at least a half hour.  
      • D o not overheat  
      • S melly process!
    • Containers
      • Must be sterile
      • R inse with 9:1 water:chlorine  
      • P lastic cups, milk cartons, egg cartons, N ewspaper, and yogurt cups, soil blockers
      • P ut holes in bottom for drainage and oxygen supply to roots
    • Containers
      • P urchase plastic ‘flats‘and ‘trays’
      • Different sizes for different crops
    • Planting Your Seed
      • F ill it to within 3/4 inches from the top with moistened medium
      • Gently tamp down (do not press hard!) and create a flat, uniform surface
      • Remove rocks, sticks, and/or large clumps of soil from the surface  
    • Label!
    • Planting Depth
      • S eed packet
      • T wice the diameter rule
      • M ost plants germinate in dark
      • Plant more seeds than you will use
    • Water!
      • A fter seeds have been sown, water with room temperature water
      • D on ’ t wash the seeds away or change their depth with heavy watering
    • Water!
      • ‘ W icking ’ action works
      • Or… cover the container with a plastic bag or sleeve
      • O ne inch away from the soil and there should be air flow
    • Water!
      • Soil should remain moist throughout germination  
      • Remove the plastic as soon as the seedlings emerge
    • Water!
      • After seedlings emerge, watering increases  
      • If utilizing the wicking method, run water through containers occasionally to keep plants healthy and inhibit disease.  
      • The soil should always be moist to the touch and not dry or soggy.
    • Temperature
      • Temperature is probably the most important factor in starting seeds indoors without a greenhouse.  
      • O ptimal germination temps for different crops
      • P urchase seed starting heating mats
      • S tart seeds that require lower temperatures to germinate such as: lettuce, brassicas, and alliums  
    • Temperature
      • A fter germination, move seeds to cooler temp.
      • 55-60 degree F night temp
      • 65-70 degree F day temp  
      • D ifferent temperature for different crops  
    • Light Requirements
      • I ntense light needed after germination  
      • South facing windor- at least four hours of direct sun
      • 40-watt cool fluorescent tube or special plant growth lamp (HPS)
      • S ixteen hours each day
      • 6-12 inches above seedlings
    • Buy or Build Your Own!
    • Transplanting
      • T rue l eaves ?
      • Time to step-up to soil mix
      • S elect strongest seedling
      • T hin by cutting top of plant off ; don ’ t disturb roots  
      • ‘ S trongest ’ criterion- straight, strong stems, no discoloration and/or odor throughout entire seedling, and lush leaf growth
    • Transplanting
      • Be very gentle with your seedling and try to avoid tearing the roots in the process!  
      • H andle by leaves and not delicate stems
    • Transplanting
      • Fill a container to about an inch from the top (to allow room for watering)
      • M ake a hole in the center of the container
      • Gently place the plant into the whole and make sure that the roots have room to spread out
      • The depth of the plant should mirror the depth at which the seedling was originally at in the old container
      • Gently tamp soil down around the plant and water softly  
    • Hardening Off
      • L ast step - essential to ensure healthy, vigorous plants
      • P rocess of acclimating young plants to the outdoors from their indoor environment
      • G radually lowering temperatures, relative humidity, and reducing water about one- two weeks before planting in the garden
      • M eant to slow plant growth, not stop
      • A fter proper hardening, cold-hearty plants can be planted outdoors and light frosts will not damage the m (even tomatoes!)
    • Hardening Off
      • S haded area protected from intense wind, full sunlight, and very low temperatures
      • O ptimal temperature- 45-50 degrees F
      • Cold-frame is ideal
    • Transplanting to Field
      • Raised beds
      • Correct depth
      • Stimulate roots
      • Mulch
      • Water-in
      Transplanting to Field
    • Direct Seeding
      • Some plants respond better to direct seeding and should not be transplanted (dill, carrot, cilantro)
      • Usually larger seeded veggies, root crops, flowers
