Syngonium Care

Syngonium, commonly known as Arrowhead Plant, is a captivating houseplant with arrow-shaped leaves. It thrives indoors with proper care, making it a favorite among plant enthusiasts. This guide breaks down the essentials of Syngonium care, covering everything from light requirements to common issues. By following these tips, you’ll ensure your Arrowhead Plant remains vibrant and healthy.

Scientific Classification

Plants have scientific names and groupings, just like people have last names and families. For the Syngonium plant, these are the key categories it falls under:

  • Kingdom: Plantae
  • Phylum: Tracheophyta
  • Class: Magnoliopsida
  • Order: Alismatales
  • Family: Araceae
  • Genus: Syngonium
  • Species: Varies (e.g., Syngonium podophyllum)


When caring for your Syngonium, light is like the main course of its daily meal. Your plant thrives in bright, indirect sunlight. This means you should place it where the sun’s rays don’t hit it directly, but it can still bask in plenty of light. Too much direct sunlight can burn its leaves, so avoid that. However, Syngonium can handle lower light areas but at the cost of slower growth and less vibrant leaves. Your goal is to find a spot that’s just right, where your plant can glow without getting scorched. A north or east-facing window could be the perfect spot for your Syngonium to live happily.


You need the right amount of water to keep your Syngonium healthy. Syngoniums like their soil to be slightly moist, but not soaked. Water your plant when the top inch of the soil feels dry to the touch. This usually means watering once a week, but the schedule can vary with different home environments. If you over-water, your plant’s roots can rot, and under-watering can make the leaves turn brown and crispy. So, you must find a balance. In winter, Syngoniums need less water because they grow more slowly. Always use a pot with drainage holes to avoid excess water sitting at the bottom. This way, your Syngonium gets just enough water to thrive without the risk of rotting.


Soil is like a cozy bed for your Syngonium’s roots. It holds nutrients and water that the plant needs to grow. You want the soil to be well-draining, so it’s moist but not soggy. This means water can flow through it easily without staying around for too long which could hurt the roots. A mix made for indoor plants or a tropical mix is best for your Syngonium. You can even add some perlite or orchid bark to the mix. These bits help keep the soil light and airy, giving the roots room to breathe and grow. Remember, the right soil helps prevent over-watering issues, which is a common mistake. Proper soil care ensures your Syngonium has a healthy foundation to thrive and bring green beauty into your home.


The temperature for Syngonium plants should be just right, not too hot and not too cold. Think of it like the temperature you’d be comfortable in while wearing a T-shirt. They thrive best when the temperature is between 60°F and 80°F. If it gets colder than 50°F, your Syngonium might start to suffer. That means keeping them away from drafty windows or doors during the winter and not putting them right by the air conditioner in the summer. Just like you wouldn’t want to sit in a chilly draft or right in front of a blasting air conditioner, neither does your Syngonium. Keeping the temperature steady and comfortable helps ensure your plant grows well.


Humidity is the amount of water vapor in the air. Syngonium plants like it when the air is not too dry. They prefer an environment similar to what they would have in the wild, which is usually a humid place. In your home, they do best when the humidity level is between 50% to 60%. If the air is drier than this, your Syngonium might not grow well. The leaves can turn brown at the edges if the air lacks moisture. To help your plant, you can mist it with water, use a humidifier in the room, or place the pot on a tray of wet pebbles. By doing any of these, you add moisture to the air around the plant, which is just what it needs.


Fertilizer is like vitamins for your Syngonium plant. It gives the plant important nutrients that help it grow healthy and strong. Your plant’s soil doesn’t always have enough nutrients, so fertilizer adds more. It’s like when you eat a healthy meal with lots of good stuff your body needs. In the case of Syngonium, the type of fertilizer and how often you use it are key things to know. You should use a balanced, liquid fertilizer most of the time. You can use this kind every month during the spring and summer when your Syngonium is growing. But in the fall and winter, you can take a break and not fertilize at all. This is because your plant grows more slowly or stops growing during the colder months. So remember, just like you might take a vitamin to stay healthy, your Syngonium needs its type of vitamins too, through fertilizer.

Size & Growth Rate

Syngonium plants are fast-growing. They can get quite large if you give them the right care. Indoors, they usually grow to be about 3-6 feet tall. Their leaves change shape as they mature, starting as arrow-shaped and then developing lobes. When allowed to climb or given support, Syngoniums can grow larger and show more of their mature leaf forms. However, without enough space or light, their growth can slow down. You can keep them smaller by pruning. This means cutting back some parts of the plant to maintain a certain size or shape. Pruning can also help the plant grow more full and bushy. Remember, a happy Syngonium will grow quickly, so be ready to give it the room it needs.

Common Issues

Syngonium plants can face some problems that impact their health. Pests like spider mites and aphids can attack your plant. These tiny bugs feed on the sap, weakening your Syngonium. Yellow leaves might mean too much water or not enough light. Brown, crispy leaf tips can suggest low humidity. Root rot can happen if your plant’s soil is wet for too long. Watch out for these issues to keep your plant strong. If you see them, you’ll need to act fast to help your plant recover.


Toxicity refers to how poisonous a plant is if eaten or touched. The Syngonium plant is toxic. It contains a sap that can be harmful. If you or a pet chews or swallows the leaves, it can cause irritation. Your mouth and throat might feel like they are burning. You might also feel sick to your stomach. If the sap gets on your skin, it could make you itch or develop a rash. Therefore, it’s important to keep Syngonium away from kids and pets. If someone does eat part of the plant, they should see a doctor. Always wash your hands after handling the plant to stay safe.
