TEST: Primarily on Cuttings and Safety
Grow seedlings/cuttings that are healthy. Take from healthy plants. Make sure the seeds have been stored properly within the time limits of the species you are working with.
Pests of seedlings/cuttings
damping off – fungal from a number of different pathogens; conditions for growth: cold damp soil, old seed, and lack of air circulation
Treatment: use fresh seeds, keep the temperature closer to ideal temperature of that plant and use a fan to encourage decent air circulation
fungus gnats – small airborne insects; conditions for growth: very wet soil with decaying organic matter; adult flies do not harm plants – but the larvae can damage your seedlings
