  • 3. Why should I start from seed?
    • Saves money
    Packet of 50 seeds Transplant $2.75 at Lillian Goldman Visitors Center and in the Seed Savers Exchange catalog $1.75 at Lillian Goldman Visitors Center $3.00 in Seed Savers Exchange catalog

  • 5. Why should I start from seed? It’s a great way to get to know your garden on another level!
  • 6.
    • Once you’ve picked out your heirloom seeds, determine whether they should be
    • Direct Seeded
    • - or -
    • Started Indoors
  • 7. Direct Seeded vs. Started Indoors
    • Consider the length of your season and ground temperature.
      • Tip: Start heat-loving plants like tomatoes, peppers and eggplant indoors.
    • Some plants just don’t like to be transplanted: beans, corn and peas are examples of this.
  • 8. Direct Seeding
    • Aerate soil and mix in compost two weeks prior to planting.
    • Plant when soil is workable.
    • Be sure to water them in well.
      • You can save yourself this step if there is a period of gentle rain predicted.
    • Don’t plant too deep or pack in soil on top.
    • Seed liberally; thin later.

    2-4 weeks before last frost Cucumbers and melons 5-6 weeks before safe planting-out date Cole crops 5-6 weeks before safe planting-out date Lettuce 6-8 weeks before last frost Tomatoes 6-8 weeks before last frost Eggplant 8-12 weeks before last frost Peppers 12-14 weeks before safe planting-out date Onions
  • 10. Starting Your Seeds Indoors
    • Choosing a Medium
    • There are many kinds of media that can be used to start seeds—or you can experiment and make your own!
      • Peat based
      • Compost blends
      • Soil-less potting mixes
    • Choosing a Container
    • Be creative.
    • Seeds don’t care what they’re planted in, as long as it can hold a form and allow for drainage.
    • Up-cycle!
  • 11. Starting Your Seeds Indoors
    • Decide what type of container you want to start your seeds in.
    • Wipe out any debris that doesn’t belong.
    • You may need to wet your substrate (media) with water prior to seeding out.
    • Refer to seed packet to determine seed depth and temperature conditions.
    • Try to space seed evenly in the container so seedlings don’t have to compete for resources.
  • 12. Starting Your Seeds Indoors
    • Light , Heat and Humidity
    • Light and heat are two important factors to consider when raising seedlings for transplant.
      • Be familiar with specifics for the varieties you want to grow.
    • Window light is great if you have it.
      • Rotate plants ¼ turn each day to prevent leaning.
    • Grow lamps are an easy alternative for spaces that lack adequate natural light.
  • 13. Starting Your Seeds Indoors
    • Light , Heat and Humidity
    • If starting your seeds in a cool setting, use a warming pad.
      • Make-do options include household heating-pads on the lowest setting, LED lights covered with a thin layer of plastic, top of the fridge, or a sunny window—just try to find a nice warm spot in the house.
    • Know what temperature is optimal for your seeds to germinate.
  • 14. Starting Your Seeds Indoors
    • Light, Heat and Humidity
    • Don’t overwater, especially before seeds germinate.
    • Lightly spray with moisture so as not to wash away seeds.
    • Cover containers with plastic (if you can) to retain humidity.
    • Once seeds germinate allow for more air flow (remove any coverings on them).
  • 15. Seedling Anatomy
  • 16. Raising Your Seedlings for Transplant
    • Love your seedlings!
    • Brushing gently with your hand helps simulate the wind and strengthens cell walls.
      • A kind of hardening off before being hardened off.
    • Watch them—the only way to detect early decline is to be attentive to how they are doing.
  • 17. Hardening Off Your Seedlings
    • Once seedlings have a second pair of true leaves and their root mass is sturdy (several ways to check this), put them outside to harden off.
    • You’ll want to harden them off for about a week before planting so your seedlings can adjust to the elements. You can still bring them indoors in case of frost.
  • 18.
    • Place seedlings in a shady spot for 2-3 days.
      • Cover, if possible, with row cover.
    • Move them into the sun for 2-3 days. Be sure to water during the day if it gets hot!
      • This may be a good weekend activity.
    Hardening Off Your Seedlings
  • 19. Transplanting Your Seedlings
    • Tips for Transplanting
    • Once your seedlings have been hardened off, transplant them into your garden.
      • Be fairly gentle with them
      • Spacing
      • Trellis needs
    • Water your transplants well an hour or two before planting into the garden—you don’t want to put dry plugs into the soil.
  • 20. Transplanting Your Seedlings
    • While planting:
      • Notice root system
      • To agitate or not to agitate?
    • Be sure to fully cover the potting mix with garden soil.
    • Water them in.
    • In special cases you may want to cover your transplant when it first goes into the ground for bug protection.
      • Ex. Eggplant
  • 21. Caring for Your Transplants
    • Expect some transplant shock at first.
      • Healthy plants should begin actively growing within a week.
    • Keep transplants well-watered the first week they’re in the ground.
    • Watch for frost or severe weather for the first week or two. If possible, cover your transplants in the event of frost or high winds.
    • Monitor after they go into the ground—it is easier (and healthier) to prevent rather than react to pests and disease.
