|I'm not sure where on the stem to cut my Phalaenopsis orchid.
|Most growers cut back the flower stalk (called inflorescence) after blooming to allow the plant to rest. The belief is that the next flower spike will be stronger.
For phaleaenopsis orchids, some growers induce a secondary flower spike by cutting above just above dormant buds that are located below the first flower on the stem. Sometimes, a small baby plant (called a keiki) will develop instead. Leave it until roots develop and then it can be removed and potted. I hope this information helps!
