Care Essentials

Get to Know Your Philodendron Imperial Red

Keep an eye out for pests — regular leaf inspections catch problems early.

Light

medium to bright indirect

Most comfortable in medium to bright indirect light. Avoid prolonged direct sun exposure.

💡 Grow lights: Thrives under artificial grow lights (LED or fluorescent, 10-12 hours/day). A great option if your space lacks natural light.

Watering

every 10-14 days

Let the soil dry out significantly between waterings — this plant is very sensitive to overwatering. When in doubt, wait another day.

Humidity & Temperature

Not fussy about humidity. Handles average indoor conditions without issue.

Standard room temperature (60-80°F / 15-27°C) is perfect. Avoid cold drafts and sudden temperature swings.

Soil

Standard well-draining potting mix works well. Add perlite for extra drainage if you tend to overwater.

Difficulty intermediate

Pests (2 topics · 2 cases)

Why does my Philodendron Imperial Red have aphids?

Aphids are listed among the pests that attack Red-leaf Philodendron (the species group to which Philodendron Imperial Red belongs), and they excrete honeydew that supports black sooty mold growth on the large, glossy, dark green leaves of this cultivar

80%
Cause

Aphids are listed among the pests that attack Red-leaf Philodendron (the species group to which Philodendron Imperial Red belongs), and they excrete honeydew that supports black sooty mold growth on the large, glossy, dark green leaves of this cultivar. The same Plant Doctor chart links a sticky, mottled leaf surface directly to aphid and whitefly infestation.

Solutions
  • Pick aphids off the leaves with your fingers as soon as they appear, and spray the infected parts with insect soap or apply a biological control.
  • Wash away the sticky honeydew and any developing sooty mold by giving the foliage a gentle shower, then isolate the plant so the infestation cannot spread to neighbouring houseplants.
Prevention

Quarantine new houseplants for a few weeks before adding them to the collection, inspect the leaf undersides weekly, and maintain steady warmth, high humidity and a shady to filtered-sun position so Imperial Red stays vigorous and resistant to aphid outbreaks.

Why does my Philodendron Imperial Red have spider mites?

Spider mites are listed among the pests that attack Red-leaf Philodendron (the species group to which Philodendron Imperial Red belongs), feeding on the foliage of this compact, erect climber with large, arrow-shaped leaves

80%
Cause

Spider mites are listed among the pests that attack Red-leaf Philodendron (the species group to which Philodendron Imperial Red belongs), feeding on the foliage of this compact, erect climber with large, arrow-shaped leaves. The same Plant Doctor symptom chart lists spider mites as a cause of small, spindly growth and dull, discolored leaves on indoor tropicals.

Solutions
  • Check under the leaves for spider mites; if any are found, cut away the affected parts and spray with insect soap or apply a biological control.
  • Spray the infected parts with insect soap and/or use a biological control, repeating until the infestation clears, and isolate the plant from nearby houseplants during treatment.
Prevention

Keep Imperial Red in a warm, shady to filtered-sun position away from direct sunlight, with high humidity maintained by frequent misting, and inspect the leaf undersides weekly to catch mites early.
