spider mites on Philodendron White Knight
Quick answer
If your Philodendron White Knight has spider mites, the most likely cause is: Spider mites thrive on philodendrons kept in dry indoor air; the philodendron care guide ties dry, crumbling leaves directly to heat that is too high and humidity that is too low, both classic conditions that let microscopic red spider mites establish, and warns that fine webs at the leaf and stem axils with mottled, gray-brown, crumbly foliage are the visible sign of an active colony on philodendrons like White Knight.
Start here:
- 1. Rinse the entire plant above and below the leaves with a vigorous stream of tepid water to physically dislodge mites and break the fine webs they spin at the leaf axils.
- 2. After rinsing, mist the foliage weekly with clear tepid water and raise humidity around the White Knight so the air no longer favors another mite outbreak.
