Ming Aralia problems & how to fix them

Polyscias fruticosa

Drooping, yellowing, brown tips, or a plant that just won’t thrive? Here are the most common Ming Aralia problems, what usually causes them, and how to turn things around.

Common problems

Cold damage

Anything below about 15 C or a winter draft triggers wholesale leaflet drop. Tissue injury from a cold draft, a chilly windowsill, or a night outdoors below the plant's tolerance. Damaged leaves will not heal, but if the stems and roots survived, new growth typically appears within three to four weeks in a warm, stable spot.

Root rot

Its fine roots rot fast in heavy, wet soil. A fungal or bacterial infection of the roots, almost always triggered by soil staying wet too long. Caught early, most plants recover within a few weeks after repotting; if most roots are already mushy, recovery is uncertain.

Spider mites

Dry air brings mites to the dense, ferny foliage where they're hard to spot. Tiny sap-sucking mites that thrive in warm, dry air and leave fine webbing and speckled leaves. Caught early they are very treatable; most plants recover fully within 3-4 weeks of consistent treatment.

Transplant shock

It sulks and sheds after repotting or relocation — change one thing at a time. Stress that follows repotting or planting, caused by disturbed roots that temporarily cannot supply enough water. Most plants stabilize within two to four weeks with steady moisture and reduced stress, though some leaf loss along the way is normal.

The mistakes that most often kill it

  • Cold drafts or a chilly room stripping it to bare stems.
  • Overwatering the fine root system in a heavy mix.
  • Constantly moving it, restarting the shock-and-shed cycle.
