Orchid Flower Wilt from Top Down: Normal Senescence

Top Flower Wilting on Phalaenopsis: End of Bloom Cycle

Lynn's orchid has a wilting top flower on the stem (not the oldest). Flowers fine since June. Concerned about light, possible overwatering. Asks if this condition is known and how to save remaining flowers.

Expert Response

Lynn, cause uncertain, but since flowering since June, likely normal cessation rather than senescence. Normally first flower opens first and drops first. Plant probably finishing flowering phase, redirecting energy to new roots and leaves. When flowering finishes, repot to provide best conditions for new growth. At repotting, examine roots: healthy are firm, turn green when wet; mushy roots are dead, remove before repotting.
