Why is my syngonium turning brown? (Causes and Solutions)

Arrowhead plant leaves turning yellow and brown occur for a variety of reasons. Many houseplant enthusiasts have experimented with arrowheads.

Below are some of the reasons why arrowhead plants develop brown leaves. Let’s explore each cause and get to the bottom of it.

lack of humidity

Arrowhead plants like a warm, moist environment. The condition ensures faster growth and the production of beautiful leaves.

Low humidity around the plant causes the tips and edges of the leaves to turn brown. In addition, the leaves eventually weaken and wither.

Increasing the humidity around the houseplant will prevent the leaves from turning brown and dropping. Arrowhead plants like high humidity because they are tropical plants.

I recommend installing an electric humidifier to increase humidity by misting the leaves. Be sure to turn on equipment in the winter, as humidity levels are dynamic.

Over-fertilization

Arrowhead plants thrive in organic compost. These houseplants do not eat much, although fertilizer is very essential for better growth.

But too much fertilizer will cause arrowhead leaves to turn brown. Salt buildup around the roots becomes toxic to the plant.

Excess manure prevents the roots from carrying out their physiological activities. Lack of water and nutrients causes blackening of the leaves.

Be sure to rinse the potting soil thoroughly with water. Helps remove excess minerals around the roots. I recommend using organic compost instead of fertilizer.

Do not forget to apply fertilizer to the plant in spring and summer. Avoid the winter season as the arrowhead plant enters its dormant stage.

lack of soil moisture

Arrowhead plants enjoy moderate soil moisture to facilitate faster growth and development of beautiful leaves. Water helps the plant to carry out its physiological processes.

If you notice the tips of your arrowhead plant’s leaves turning brown and crispy, the soil is probably too dry. If the condition persists, the houseplant’s leaves will droop and drop.

The constant lack of water is what causes the leaves to darken. Note that the brown tips of the leaves will turn green again after watering.

Plant parents need to cut off the tips and brown edges of the leaves to revive the plant. Additionally, they should consider a strict watering schedule to prevent the problem from recurring.

Be sure to water the houseplant two to three times a month during the growing season. But limit the frequency of watering in winter.

direct sun exposure

Arrowhead plants are native to the rainforests of Latin America. These plants grow below the canopy, where they receive indirect sunlight.

Leaves turning brown may be due to direct sun exposure. The heat of the sun causes sunburn on the leaves. Reviving burnt leaves can be a daunting and empowering experience.

Syngonium plants are too sensitive to direct sunlight. The best option is to change your current location to an area that receives filtered sunlight.

Remember to expose the plant to direct sunlight for three to six hours a day. It will help improve the health and well-being of plants.

excess water problem

Overwatering is the main cause of arrowhead leaf browning. It is produced by improper soil drainage which facilitates swamps and streams.

If you notice your houseplant’s leaves turning brown and wilting, it’s due to an overwatering problem. Consider appropriate measures at an early stage to save the plant.

Soggy soil favors the development of root rot due to poor aeration. Damaged roots inhibit water and mineral uptake.

You will also notice that the leaves of the arrowhead plant turn yellow and brown. The best solution is to transplant the plant into a new container with fresh potting soil.

Do not forget to cut the damaged roots with sterilized scissors. Follow the Arrowhead Plant Care Routine for best results.

thermal stress

Arrowhead plants are too sensitive to high temperatures. The houseplant usually shows heat stress on its leaves.

Arrowhead leaves turning brown are caused by high heat around the plant. The heat burns the leaves and gives an unsightly appearance.

The best solution is to provide an optimum temperature between 65 and 85OF during the day. Nighttime temperatures should be above 60°F to promote better leaf development.

leaf spot

Arrowhead plants are most vulnerable to leaf spot. The fungal disease is responsible for brown spots and leaf spots (Source: Pennsylvania State University

Apply a fungicide to the plant to get rid of the condition. Note that the brown arrowhead leaves take time to return to their usual color.

harmful insects

Arrowhead plants are more susceptible to insect pests. The most common pests that attack the houseplant are spider mites, scale insects and scale insects.

These sap-sucking insects often pierce the leaves and exhaust them. Frequent drilling eventually accelerates blackening and yellowing of the leaves.

The solution is to move the plant to a room with the right lighting conditions. Also spray the houseplant with a horticultural insecticide to eliminate these pests.
