While a large number of seeds will germinate, usually most of the seedlings will die very soon
In some cases the seedling will die because of damping, while in other cases, the snails, worms in the soil will eat the seedlings.
Sometimes slugs are also found in the soil.
So now some of the seed sellers are also supplying cocopeat with the seeds
This is a sterile medium, without the disease causing fungus which cause seedling damping.
