I have a yellow Arbutilon plant in my conservatory.
Does it drop its leaves in winter ?
Should I cut it back later in the year as it is getting
rather leggy ?
Can I leave it in the conservatory over the winter ?
Now would be a good time to trim it very lightly, as it starts to go dormant. Leaf drop is common when humidity or temperature changes quickly. It would be well suited for indoors.
