Tibouchina Urvilleana and the weather. We've got a Tibouchina and are facing its first winter. We live in Northern Spain (same climate as Ireland's, for instance). It is atlantic climate. I am consulting this forum because I am a bit afraid of frosts, which are not very frequent here but they happen every now and then. Our chief gardener told me to cover the Tibouchina with a plastic (which I hate). However, I've bought some plastic in case it gets really scary. BUT the reason for my writing is that some people -more than one- have told me to place a bucket with water by the plant to prevent from freezing. This is what I've done so far: I've place a couple of transparent plastic pots (so they are not very noticiable) with water. May be not very scientific but nevertheless worth trying. I'll let you know what happens! Excuse dull expression: I am a Spaniard!
