Nephthytis
Nephthytis, or arrowhead (Syngonium podophyllum) is a slow-growing, vining, evergreen, perennial, houseplant originating from tropical forests in Central and South America. This plant can reach up to 4 feet or more in height, with lance-shaped leaves that are prominently marked with white and green hues. It is popular for its ease of care and ability to tolerate low light. Nephthytis are long-lived if given proper care.
Water your Nephthytis regularly, but don't over water. Water when the top inch or two of the soil feels dry. Make sure you water the plants base, not leaves and flowers, as this can cause rot and disease. The more light the plant receives, the more water it needs. Allow the soil to dry between waterings and avoid overwatering the plant or keeping it too wet, as this can lead to root problems.
Nephthytis thrive in bright, indirect light. Moderate morning and afternoon sun is preferred, especially during summer months, but avoid harsh mid-day sun as this will burn the foliage. Too little light will slow or stunt growth and decrease leaf coloration. The ideal light level can be full shade to partial sun. Leaves may become washed out and become more all-green if the plant does not receive enough light.
Normal household temperatures ranging from 65 - 75 degrees Fahrenheit (18 - 24 degrees Celsius) during the day and 60-70 degrees Fahrenheit (15 -21 degrees Celsius) at night are ideal. Temperatures lower than these can cause dormant periods and too high of temperatures can cause your plant to wilt.
Nephthytis prefer high humidity. Increase humidity in dry homes by grouping plants together and misting the leaves in between waterings. Avoid hot and cold drafts that will damage delicate foliage.
Nephthytis prefer a well-draining soil mix. A general potting mix, or one that is specifically made for tropical plants, will work well. If you choose to make your own mix, consider adding some perlite or orchid bark to improve drainage and aeration.
Fertilize your Nephthytis every two months during the growing season (spring and summer). Use a balanced liquid fertilizer diluted to half strength. Fertilize less during winter months, once every two to three months. Ensure that the soil is damp before applying fertilizer, and never let it dry out before or after fertilization.
Spider mites are the most common pests. Spider mites are hard to spot at first; they look like tiny dots on the underside of leaves near the stem. An outbreak is best taken care of by wiping down the foliage with a damp cloth to wipe away spider mites. If the infestation has become severe, you may want to search for systemic insecticides, as these are absorbed by the plant and will target pests on its leaves. Natural methods like neem oil or horticultural soaps may also be effective.
Every two to three years, it's time to repot your plant with fresh soil. Spring and early summer are the ideal times to repot. Nephthytis perform best when pot bound and should be placed in a slightly larger pot than the current one when it's time to repot.
Pruning is a great way to keep your Syngonium looking its best. Trim back any leggy stems and remove any damaged or dead foliage to encourage new growth. Prune and pinch back regularly to encourage bushier growth, but do not cut too close to the stems or foliage as this may decrease the visual appeal of the plant.
Mulching is not necessary but can be beneficial for Syngonium plants. Mulch helps keep the soil moist and feeds the plants with essential nutrients. Avoid mulching with a heavy material, such as clay, as this can trap moisture and lead to root rot.
Nephthytis can be propagated by stem cuttings. Take cuttings from the tips of healthy stems in the spring or summer. Dip the cuttings in a rooting hormone and place them in moist potting mix. Keep the topsoil consistently damp and place in a warm location with indirect sunlight. Rooting should take place after several weeks.
Nephthytis are climbers, and do best when given a trellis or other support to climb on. This helps keep the plant upright in their container. Support can also be provided with a moss pole or simply a stake. During the summer months, you may consider placing your Nephthytis outdoors for more sunlight and humidity.
Nephthytis come from warm, tropical environments and do not tolerate cold temperatures. You can help your plant stay healthy by giving it a rest period in the winter months. During this time, reduce watering and place your plant in a cooler location in your home, ideally around 60-70 degrees Fahrenheit (15-21 degrees Celsius).
Nephthytis is toxic to cats and dogs if they eat it. It can cause vomiting, drooling, confusion, and difficulty breathing in pets. If your pet eats the plant or any part of it, contact your veterinarian immediately.
