TROUBLESHOOTING GUIDE – SEEDS
Seed Starting
  • Check packaging date on seed packet. Do not use old seed.
  • Check soil moisture at least twice a day. Don’t allow seed to dry out.
  • Tiny seeds need light to germinate. Sprinkle these on the surface of soil and press.
  • Medium and large seeds need darkness to germinate. Cover them with soil.
  • Most seeds require 70 to 75 degrees to germinate. Soil should not be too hot or cold.
  • Bury seeds 2 to 3 times their diameter. Do not bury too deeply.
  • Make sure seeds are in good contact with soil. Tamp down after planting.
  • Make a ball of soil…if you are able to knock it apart easily, the texture is correct.
  • Some seeds require cold treatment, water treatment or scarification.
  • Seedlings
  • Do not over water seedlings. If using a container, water from the bottom up.
  • Do not overcrowd seedlings. Follow package directions for thinning(1 to 2 in.).
  • Watch out for pests. Young seedlings are vulnerable to damage.
  • Leggy seedlings: inadequate light, overcrowding, high temperature.
  • Seedling Recipe
  • 1/3 Potting Mix, 1/3 Vermiculite, 1/3 Perlite.
