Corn Plant, Yucca, and Ficus Decline: Light, Pests, and Compost Mistakes

Large, mature specimens of Dracaena massangeana, Yucca elephantipes, and Ficus benjamina declined after years of compost top‑dressing, compost tea, and excessive light exposure.

Species‑Specific Issues

• Corn plant: Yellowing leaves from too much direct sun (prefers low light) and possible hard‑water buildup.
• Yucca: White powdery film is natural; mealybugs appear as cottony or powdery deposits.
• Ficus: Sticky “honeydew” on leaves signals mealybugs or scale.

Pest Treatment

Spray all surfaces thoroughly with 5 parts water, 1 part alcohol, plus a squirt of liquid soap. Cover every leaf and stem to reach invisible crawlers.

Stop Using Compost Indoors

Compost doesn’t break down well inside, attracts pests, can acidify soil, and creates odors. Switch to sterile, peat‑perlite mixes.

Starting Over

Root cuttings in small pots with porous mix. Provide appropriate light: corn plant in bright indirect, yucca in full sun, ficus in bright indirect.
