The Greenhouse
Our sensitive plants have had a lovely period of around 12° C during daytime with only a couple of days with the mercury in the red zone. A temp outside of -7° C, gives -1° C in the greenhouse. This shouldn’t trouble the Crocosmias, Rosmaries and first year Libertias. The Euphorbia characias ‘Wulfenii’s manage much lower temperatures, but we like to give them a good start prior to spring planting.
