Grey looking Lavender....And dried up Photinia.....SNOW!!!

[Rose77]

I planted some young lavender shrubs and Photinia during september and they began to grow quite well....until they met with an unusually cold and snowy spell with temperatures falling to -7 for a week in february. Now my poor plants have lost their green leaves, the lavender looks all grey and dead and Photinia all brown?. I have cut back a third of the stems to get rid of any dead growth and I noticed that the stems inside are still green where I cut so do you think there is a chance they havent died? Or should I completely cut the bushes back to the ground getting rid of all the dead foliage or will that completely kill them off?
P.s I havent watered any of the lavender bushes them since....
Thankyou!

I'm not familiar with photinia, but I grow a lot of lavender, in (I presume) colder climate than yours. The lavender goes grey and dormant in the winter, but comes back just fine when the weather warms up.

If you see green where you pruned the photinia you should have no problem but you might want to give it some fertilizer.
