Yeah they will be dead or at least not worth trying to nurse back to
life if you want any tomatoes. Keep the Yew until at least autumn
next year 2013.

About half of my bedding plants are also dead, nasty freezing snap
with snow on the mountains.

We don't bother with anything "tender". The cold snap last week has
done for the fresh leaves on the (wild) roses and some of the black
thorns. That's all shrivelled and brown but more fresh green growth
is appearing.
