Im growing basil for the first time from seeds. At the moment the
seedlings are sitting in my 40-cell propagator (with transparent cover)
and there are around 5-10 seedlings per cell (each cell is about an inch
in width and length).
They are now starting to show their 2nd set of leaves, ie, they all now
have 2 larger leaves and 2 small ones (1-2mm). The seedlings are about
an inch or more tall.
My question is, when should I transplant them to my mini greenhouse
outside in the garden? I understand it is a question of outside
temperature and also the size of the seedlings. But I have seen various
inconsistent bits of advice online.
I am worried about the cold predominantly. It is mid April now and I
live in Wiltshire, but I dont know how much cold basil can resist or if
its just fine to prick out and transplant now.
