Why Philodendron gets stem rot
Philodendron spp.
A Philodendron cutting suffering stem rot, leaving only a small node with an aerial root nub and no foliage.
Other documented causes on philodendron:
- • Stem rot (bacterial soft rot) in Philodendron occurs when moisture accumulates at the stem base or leaf axils, creating entry points for Erwinia chrysanthemi and other bacteria. Unlike root rot which affects below-soil tissue, stem rot targets above-ground meristematic tissue. Symptoms include soft, mushy tissue at soil line, foul odor, and progressive yellowing of attached leaves. High humidity without adequate airflow is the primary trigger, especially in self-heading varieties with dense leaf clusters.
