Growing at the wrong time of year could be fatal to sensitive seedlings, so mother nature ensures they don’t grow until the right conditions are met. Some seeds need a period of darkness before they emerge, while other seedlings need light to germinate. Seeds contain enough food in order to feed the embryonic plant during germination. Once the newly emerged seedling reaches the light, photosynthesis takes over.
As a rule, small seeds need light to germinate as the seed doesn’t contain enough nutrients to sustain the emerging seedling long. Therefore, it is critical that the seedling reaches a light source as soon as it emerges from the shell.
When sowing seeds on the surface, ensure the soil is already moist and press lightly to prevent the seeds from being blown away.
