Arrowhead plants are popular indoor plants known for their striking arrow-shaped leaves. These beautiful houseplants require consistent care and attention to ensure that they stay healthy and vibrant. One of the most crucial factors in maintaining your arrowhead plant is its watering schedule. Understanding how often to water an arrowhead plant is crucial for the plant’s overall health and longevity.

In general, arrowhead plants need to be watered every 1-2 weeks, depending on various factors such as temperature, humidity, and soil type. To ensure proper care for your plant, it’s essential to establish a schedule for checking the soil instead of following a fixed watering routine. This approach allows you to adjust the watering frequency based on the plant’s unique needs, as it’s crucial to water the plant thoroughly once the top inch of soil feels dry.

Knowing the right watering routine for your arrowhead plant can significantly impact its growth and development. By monitoring the soil’s moisture levels and adjusting your watering habits accordingly, you can maintain a happy and thriving arrowhead plant, allowing it to grace your home with its distinctive beauty all year round.

How Often to Water Arrowhead Plant

Arrowhead plants generally require watering once every 1-2 weeks. However, it’s essential to consider various factors that may impact the watering frequency. Instead of following a fixed schedule, regularly monitor the soil’s moisture to determine when to water your plant.

Factors Affecting Watering Frequency

  • Temperature: Arrowhead plants thrive in temperatures between 65°F and 80°F. Higher temperatures may result in faster evaporation, necessitating more frequent watering.
  • Humidity: These plants prefer humid environments, so maintaining adequate humidity levels can help reduce the need for frequent watering.
  • Light conditions: Arrowhead plants can adapt to low light, but they prefer bright indirect light. Higher light levels may increase water consumption for photosynthesis, resulting in greater watering frequency.
  • Soil type: Arrowhead plants require well-draining, nutrient-rich, and airy soil for optimal growth. Proper soil composition, including a mix of compost, garden soil, sand, and perlite, can ensure the ideal balance of moisture retention and drainage.

Signs of Over or Under Watering

Identifying the signs that your arrowhead plant is receiving too much or too little water can help you adjust your watering frequency accordingly.

Over watering:

  • Yellowing leaves: Over watering can cause the plant’s leaves to turn yellow and feel soft.
  • Root rot: Excessive moisture in the soil may lead to root rot, a fungal disease that can ultimately kill the plant if left untreated.
  • Mold: Prolonged exposure to a damp environment may result in mold growth on the soil surface or the plant itself.

Under watering:

  • Wilting: Insufficient water can cause the plant’s leaves to wilt, even if the soil appears moist.
  • Brown leaf tips: If the leaf tips turn brown and become dry or brittle, the plant may require more frequent watering.
  • Stunted growth: Prolonged water deprivation can result in slower growth or no growth at all.

By understanding the factors that affect watering frequency and recognizing the signs of over or under watering, you can ensure your arrowhead plant remains healthy and vibrant. Regularly monitoring the soil’s moisture level and adjusting your watering schedule based on observed conditions will contribute to an optimally thriving arrowhead plant.

Watering Methods

Arrowhead plants (Syngonium) require careful watering methods to keep them healthy and thriving. This section covers two popular watering techniques: bottom watering and top watering.

Bottom Watering

Bottom watering is when you allow the plant to absorb water through the drainage holes at the bottom of the container. To bottom water your arrowhead plant, follow these steps:

  1. Fill a bowl, tray, or tub with water. Ideally, you should use filtered or distilled water to prevent mineral build-up.
  2. Place your arrowhead plant, still in its container, into the water.
  3. Wait for the topsoil to become moist. This process usually takes around 20-30 minutes, but it may vary depending on the size of your plant and the container.
  4. Remove the plant from the water and let it drain for a few minutes.

Bottom watering helps the roots receive sufficient hydration and prevents overwatering. It also minimizes the risk of bacterial and fungal diseases caused by excessive moisture on the plant’s foliage.

Top Watering

Top watering is the most common method of watering plants, where you pour water onto the soil surface. When top watering your arrowhead plant, follow these guidelines:

  1. Check the soil’s moisture by sticking your finger into the top 2 inches of soil. If it feels dry, it’s time to water.
  2. Use filtered or distilled water at room temperature to avoid shocking the plant or causing mineral build-up.
  3. Water slowly and evenly around the base of the plant, avoiding the foliage.
  4. Continue watering until water drains from the bottom of the container.
  5. Empty the saucer of any standing water to prevent overwatering or root rot.

It’s essential to adjust your watering frequency according to the plant’s needs, considering factors such as temperature, humidity, and soil type. Check the soil periodically, and make watering decisions based on its moisture content rather than sticking to a fixed schedule. Keeping these methods in mind will ensure your arrowhead plant stays healthy and well-hydrated.

Seasonal Adjustments

Caring for an arrowhead plant requires adjusting your watering schedule according to the changing seasons. In this section, you’ll learn how to adapt your plant care routine during spring and summer as well as fall and winter.

Spring and Summer

During the warmer months of spring and summer, arrowhead plants generally require more frequent watering. This is because increased light intensity and higher temperatures can cause the soil to dry out more quickly. It is recommended to check the soil every 1-2 weeks and water the plant thoroughly if the soil feels dry.

In addition to increased watering, pay attention to the plant’s overall environment. Arrowhead plants thrive in temperatures ranging from 65-80°F during the day and above 60°F at night. If your indoor environment is too dry, consider using a humidity tray or a humidifier to maintain a comfortable level of humidity around your plant.

Fall and Winter

As the temperatures drop in fall and winter, so do the watering requirements of arrowhead plants. During these cooler months, you may find that your plant requires watering less frequently. It’s still important to check the soil regularly and only water when 50%-75% of the soil volume is dry.

Take extra care to avoid overwatering during this time, as lower light intensity and reduced indoor heating can cause the soil to retain moisture for a longer period. Keep the temperature around your arrowhead plant above 60°F at night and monitor humidity levels to ensure they remain optimal for plant growth.

By following these seasonal adjustments for your arrowhead plant’s watering routine, you’ll help ensure it remains healthy and vibrant throughout the year. Remember, always adjust your care routine based on the specific conditions in your home and respond to the needs of your plant as they change over time.

Additional Care Tips


Arrowhead plants thrive in environments with moderate to high humidity. To maintain the optimal humidity levels, you can mist the plant leaves regularly, use a humidifier, or place the plant in a tray of shallow water with pebbles to increase the humidity surrounding the plant. Ensure the plant’s pot doesn’t sit directly in the water to avoid root rot. Regularly check the humidity levels to keep your Arrowhead plant healthy and vibrant.


Fertilizing your Arrowhead plant is essential for promoting growth and maintaining its vibrant foliage. During the growing season (spring to summer), fertilize the plant monthly using a fertilizer that is both balanced and soluble in water can be used to provide essential nutrients to plants. After watering the plant, it is recommended to dilute the fertilizer to half-strength and apply it for optimal results. This will help prevent potential root burn.

During the winter months, reduce the frequency of fertilization to once every two months, as the plant’s growth slows down. Always follow the instructions on the label of the fertilizer for the best results. Remember, over-fertilization can harm your plant as much as under-fertilization, so it’s essential to give your Arrowhead plant the right balance of nutrients.
