Philodendron Sharoniae Care

  • Plant in loose, well-drained soil.
  • Give this plant bright, indirect light.
  • Water when the top few inches of soil have dried out.
  • Feed with houseplant fertilizer monthly during spring and summer.
  • Give this vine a trellis, moss pole, or other support for it to climb.

Light

Philodendron sharoniae grows best in a place with medium to bright indirect light. Keep the plant out of direct sunlight, which can sunburn and damage its leaves. In low-light conditions, use an artificial grow light to provide the light the plant needs to thrive.

Soil

Plant Philodendron sharoniae in loose, rich, well-drained soil. You can use a premade aroid mix or make your own potting mix by combining equal parts peat moss or coconut coir, perlite, and organic compost.

Water

Instead of watering on a schedule, check your Philodendron sharoniae's soil moisture regularly to tell if it needs water. Water when the top two inches of soil have dried out. Check drip trays and saucers to make sure the plant isn't sitting in water, which can lead to root rot.

Temperature and Humidity

Philodendron sharoniae prefers the warm, high-humidity conditions of its native area. Ideal temperatures range from 65 to 85 degrees. In terms of humidity, 60 percent is ideal, but plants can often tolerate 40 to 50 percent humidity. Group Philodendron sharoniae close together with other humidity-loving plants to slightly increase the moisture in the air, or run a humidifier in the room near the plant.

Fertilizer

With its large leaves and tall, climbing vines, Philodendron sharoniae is considered a heavy feeder compared to other philodendrons. Feed the plant with a balanced houseplant fertilizer diluted to half strength once per month during spring and summer. Keep an eye on your plant and begin feeding in the late winter or early spring when you see it putting out new growth.

Types of Philodendron Sharoniae

  • Philodendron sharoniae 'Goat': One of the most common cultivars available, 'Goat' is a vigorous, fast-growing plant whose leaves are wide and pointed at the top, similar to a goat's horns. It's sometimes referred to as Philodendron sharoniae 'San Antonio'.
  • Philodendron sharoniae 'Mosquera': This type of Philodendron sharoniae is harder to find than 'Goat' and has leaves that are rounded at the top and pointed at the bottom. It's more compact and requires a little more light and water than other types.

Pruning

Philodendron sharoniae doesn't require pruning, but minimal pruning can keep it looking healthy. If the plant is outgrowing your space, cut back no more than 25 or 30 percent of the plant's total growth during spring or summer. Give it a trellis, moss pole, or other support so it has somewhere to climb.

Trim away dead or damaged leaves any time of year. Always use sterilized scissors or pruners to keep from spreading diseases from one plant to the next.

Propagating Philodendron Sharoniae

You can propagate a mature Philodendron sharoniae into new plants using stem cuttings. Like other philodendrons, these plants are easy to root in soil or water. Here's how.

How to Propagate Philodendron Sharoniae in Soil

You'll need potting mix, a small plant pot, sterilized pruners, rooting hormone (optional), and water.

  1. Choose a stem on the mother plant that has a node and at least one healthy leaf. Make a cut just below the node.
  2. Fill the pot with soil and add water to moisten. Poke a hole in the soil a few inches deep with your finger.
  3. Dip the cut end of the stem in rooting hormone powder, if using. Plant the cutting in the hole so the node is below the soil line.
  4. Put the cutting in a warm, humid place with lots of bright, indirect light. Keep the soil evenly moist. You'll know the cutting has rooted when you see new leaf growth.

How to Propagate Philodendron Sharoniae in Water

You'll need a glass or jar, sterilized pruners, and water.

  1. Cut a healthy stem from the mother plant, making sure it has a node and at least one leaf.
  2. Fill the glass partway with water.
  3. Place the cutting in the glass, making sure the node is below the water line.
  4. Keep the cutting in a warm place with bright, indirect light. Change out the water if it gets cloudy. When the roots are at least an inch long, you can pot up the cutting and care for the plant as usual.

Potting and Repotting Philodendron Sharoniae

Repot Philodendron sharoniae in the spring every two to three years. You'll also want to repot if the plant shows signs of being root bound—like roots growing from the hole in the bottom of the container or showing through the top of the soil. Only go up one or two inches in pot size when repotting.

Common Pests & Plant Diseases 

Philodendron sharoniae can suffer from common houseplant pests like aphids, scale, and mealybugs. Keep an eye out for signs of pests, removing them quickly when you see them. Use a cotton swab dipped in rubbing alcohol or horticultural soap to remove pests. The plant is also susceptible to root rot caused by overwatering or soggy soil.

Common Problems With Philodendron Sharoniae

While Philodendron sharoniae is a pretty low-maintenance plant aside from some basic care, there are a few signs of trouble to watch out for.

Leaves Turning Yellow

Yellowing leaves are a common sign of overwatering. Check the soil moisture, and if the soil is soggy, stop watering and let the plant dry out completely before watering again. In extreme cases, you may need to repot the plant with fresh soil.

Leaves Turning Brown

Leaves turning brown can be a sign that the plant isn't getting enough water. Stick your finger in the soil to check the moisture. If the plant is dry, give it a deep watering. Keep an eye on the soil and water then the top inch or two is dry.

Browning Tips

While underwatering can lead to dry, crispy leaves, a lack of humidity can cause browning tips. Run a humidifier to increase the humidity around your plant.
