Do You Cut Back Dendrobium Nobile?

After the flowers have finished, you can trim the stems off close to the canes. After several years, some of the older growths may become woody, shriveled and yellow-looking. As long as you have three or more healthy canes and at least one with a full set of leaves, you can cut the old unsightly growths at the base.

Should I prune my Dendrobium?

Dendrobium Orchid

If your orchid is a Dendrobium type, trimming is a little different. Trim the flowers off as they fade but leave the stem. Next year it will flower on the same stalk. Trim roots and re-pot as normal.

Should you cut off old Dendrobium canes?

In the next year's cycle, the old Dendrobium canes can still produce buds and blossom. They shouldn't be cut off or disposed of. Even when they don't bloom, they still provide nutrients, water, and energy to keep the new growth alive.
