Thanks Bill

Interesting point - early morning sunshine was blocked by a building, but 
maybe that actually made matters worse, as the sun would have been higher in 
the sky by the time it worked its way round, so could have increased the 
speed of thawing when it got there.....hadn't thought of that before. 
But it's fair to say that where one sees Olives doing OK in the UK seems 
generally to be in sheltered spots in lower-lying towns/cities, so 
microclimate/heat island factors must be at play, and less exposure generally 
I would think.    

Best wishes

Hi Mark

Was your "south-facing lawn" exposed to early-morning sunshine?

As I understand it, the rapid thaw from early-morning sunshine is what causes 
a lot of frost damage to 'tenderish' plants...

Regards,

Bill

Hello Will

I planted one several years ago in a fairly sheltered (as I thought) 
south-facing lawn in the soft south (Surrey), but quite elevated 
(600ft AOD). I rigged up a fleece-covered wooden frame to put around 
it during the winters as a precaution, and all seemed well until about 
year 5, when there was an unexpected sharp frost very early in October. 
Killed it outright.
So I think that it's not low winter temperatures that get them, but 
the early, late, or otherwise unseasonal frosts which are a feature of 
the UK climate.
