This method is similar to sowing the seed indoors in pots
with the exception that the pots are stored outside whilst the
seed germinates (see last paragraph of this page). The advantage

the amount of plants to be raised.
and position of the plants are the key factors to success. Keep
the pots in the warmest part of the garden (against a house wall
is ideal) to hasten germination and subsequent growth. The use
of cloches will assist greatly in retaining heat.

the most difficult aspect of this method - keeping the plants
under cloches and or against a house wall will raise the
temperature and permit earlier growing, but it is not an exact
science. The basic rules of no frost and a minimum soil
temperature of 15C (60F) must be achieved.
combination which can work well is to sow the seeds inside
(where they do not have to be in a light position) and the
transfer them outside when the seedlings emerge.
