Q.Dead heading spent flowers
Do we remove Christmas cactus flowers after they have stopped blooming or do we let them fall off naturally?
If we are to remove them…how do we do it i.e. from what point on the stem?
It is best to let them drop off naturally, and there is no need to deadhead them. If they are just unsightly, then there is no harm in removing them, but their natural process is best.
