Allotments 4 All

Hi Y'all

Bought a Grevillea last year, and it survived the winter, spending the coldest periods in an unheated but frost free lean to.  It is looking a bit brown on one or two branches, but otherwise seems to have come through unscathed. 

I know they don't like loads of water, but they must have some I guess.  So how much is enough?  I live in Cornwall, and as I type, it is pouring down outside while the rest of the country is basking in sun I shouldn't wonder.  T'was ever so in this county, so my Grevillea could get a fair amount of water quite naturally without me going anywhere near it with a watering can.

Has anyone any experience of these quite unusual plants?  I really am looking forward to a hot summer and seeing it flower, but just now, looking out of my window.......hmmmmm..

Thanks for any advice.
