Q.Care of Umbrella plant
Do I cut off all the dead brown stuff on this Cuperusdiandrus Umbrella Plant?

When the umbrella plant dies back to the ground in winter, you can leave the frost-damaged leaves on the ground as an insulating mulch layer. It doesn't look as clean as cutting and removing the foliage, so leave the foliage only if you like the natural look.
