  • Light: Provide bright, indirect light optimal growth.

    Temperature: 65-85 F

    Humidity: medium to high; avoid drafty areas

    Elephant ears tend to be more sensitive to low humidity. Try adding a humidity tray or humidifier nearby.

  • Water: These plants grow from tubers (geophytes), and are therefore more susceptible to root rot. Try to keep the potting mix moist but allow for the top 2” of mix to dry before adding water. Leaf tip burn occurs if left to dry between watering cycles.

    Repotting: Repot every 2-3 years into a slightly larger container (1-2” increased diameter or depth). Use a general purpose potting mix.

    Fertilizing: Either…

    1. Water Application: Incorporate fertilizer into your watering cycle once per month March through September. Dilute an all purpose fertilizer (20-20-20) by half OR use your favorite fertilizer rated for houseplant use in your water.

    2. Slow Release: Incorporate slow release fertilizer pellets into the top inch of potting soil every 6 months. Apply the rate indicated for indoor plants on the label. If no recommendation for houseplants is present, apply 1/4 to 1/2 the listed rate.
