I am particular interested in, if you soak seeds first in hot water, if they are to be placed on a heat mat, can you use miracle grow seedling soil starter, how far you push the seeds down into the soil for sowing and any other information you might have such as germination rate or other techniques to sow these seeds. Thanks so much!
These notes are a general guide, it is recommended to check specialist literature for some of the more unusual seeds in our lists
Seed Germination Theory and Practice by Professor Norman C. Deno
Some knowledge about growing from seed is necessary to germinate even the easiest seeds. Most seeds require humidity to germinate, even desert plants like Welwitschia mirabilis require that their growing medium remains moist until germination.
Most seeds require oxygen to germinate, if buried too deep in their growing medium, or if the medium is too wet, the seeds may not get the oxygen they require.
Some seeds need to be in the light (surface sown) or in the dark (sown deep enough to receive little or no light) to germinate. A rule of thumb is to cover the seeds their own width deep in the growing medium, but some seeds prefer to be sown much deeper, and some fairly large seeds like to be surface sown (or higher).
Many seeds germinate best at certain temperatures, some will germinate at a comparatively wide range of temperatures, yet others need fluctuating temperatures.
Almost all seeds are waiting in a dormant state for some outside stimulus to break their dormancy, some just need sufficiently high ambiant humidity, others need scarification, vernalization or to be passed through the intestines of an animal.
Albuca namaquensis seeds will usually germinate in 30-90 days, even under good conditions germination may be erratic.
Normally will only germinate with light so surface sow. Sow Albuca namaquensis seeds on the surface of a Well drained seed sowing mix at about 22°C.
