It has been particularly cold in these last few weeks. With regularly clear night skies and sunny but cold days, much of the frost hasn’t melted and just keeps on frosting more. Even the inside of the smaller greenhouses has frozen – which does worry me a little as they hold young plants and cuttings. The larger greenhouse is still above zero, but not by much. There are semi-tender plants in there such as the lemon, lemongrass, abutilon and the canariensis palms, all of which will be feeling the chill.
The Banksia Rose is also snuggled-up in bubble-wrap but it’s more of a thin blanket and the wind sometimes does whip through it and take it off. Fortunately, it’s still green at the moment, but there’s the rest of winter still to come.
I hope the temperature moves up a nudge so I don’t have to wonder how I can add heat to the larger greenhouse to keep it from freezing inside. Perhaps hanging a hot water bottle from the inside roof each day might be enough to keep the frost off the air.
