spider mites on Philodendron Black Cardinal
Quick answer
If your Philodendron Black Cardinal has spider mites, the most likely cause is: Microscopic red spider mites colonize philodendrons when indoor heat climbs and humidity drops, settling into leaf and stem axils where they spin fine webs and turn foliage mottled, gray, brown, and eventually crumbly.
Start here:
- 1. Blast the canopy with a vigorous water spray from above and underneath to break the webs and physically dislodge the mites, repeating every few days until no new mottling appears.
- 2. If webs return after the water-only routine, escalate to a miticide labelled for indoor ornamentals such as Dimite or Aramite, applied to the leaf undersides where the mites hide.
