Growing Notes

Too shave or not to shave? Prune off the oldest leaves as they age to have a clean textured trunk. This work is best done early and consistently, as it’s easy to do when you can get your pruners under the leaves, but once they start to lie down on the trunk it becomes much harder. Alternatively, leave the beard for a rustic natural look. In high fire areas we recommend removing the beard to reduce fire load, though as long as the fire isn’t too hot, the beard would just burn off as it does in nature.
On warmer years we see white terminal flowers in summer. Once they fade cut out the spike as low as possible. Your plant will go through a period of looking a bit scruffy, before hitting its stride again; sometimes flowering induces a second head and then later a fork in the trunk.
In drier climates this plant can be grown in part sun, but it will be more open and floppy and its typical glow becomes more muted.
