Sowing seeds in a container

Seeds sown outside are usually  sown in the soil, a natural growing medium. When seeds are sown in containers  usually an artificial growing media is used.

Seed raising mix is one example  of an artificial growing medium.
  Seed raising mixes don’t require  many nutrients, as the seedlings are pricked out and transplanted into soil or  another growing medium when they are still young.

A good growing media of any  kind provides:

  • drainage
  • air around plant roots
  • enough water for plants to use
  • nutrients
  • support for the plant in the soil.

Advantages of sowing seeds in a container

Seeds sown in a container can be  kept in a protected environment that provides their basic needs of warm  temperatures, water and oxygen. This should increase the rate of germination.

Disadvantages of sowing seeds in a container

  • Once  the seeds grow, the seedlings need to be ‘hardened off’ to get used to harsher  outdoor conditions, before they are transplanted outside in the garden or  another container.
  • ‘Transplant  shock’ can slow growth or may stop it altogether for a short time.
  • The  seedlings will take more time for the plants to reach maturity.
  • Container  sowing costs more than sowing seeds directly outside.
  • Some  seedlings cannot be effectively transplanted, for example carrots and parsnips.

Choosing containers

Seeds can be sown in all sorts  of different containers. Containers should:

  • have plenty of room for roots
  • have drainage holes in the bottom
  • be lightweight for easy handling
  • be clean.
