I planted a couple of coryldine australis plants (tall spiky purplish leaves) this summer that thrived. They provided great texture to the garden. But I am worried about them now for the winter. I read somewhere that I should tie the stems up at the top to protect them? Is there anything I can do to have them survive the summer successfully? thank you |
The Cordyline australis, or the Cabbage tree is the most cold-hardy species. It will tolerate temperatures in the low 20?s F or occasionally lower. Even so, most gardeners in cold winter areas such as yours dig the plants and take them indoors for the winter months. You can dig yours, pot them up, and keep them in a garage or basement where they will rest for the winter, or take them indoors where they will continue to grow and look lovely. Although you can try leaving yours outdoors and covering with protective material, there's no guarantee they will live over the winter months. I'd dig them up now before temperaturees get too cold. Good luck with your plants! |
