Watering Your Arrowhead Plant: A Comprehensive Guide

Understand Your Arrowhead’s Needs

The Arrowhead plant is native to tropical rainforests, and it loves moisture—however, this does not mean it requires constant watering. Overwatering can actually be more damaging than underwatering.

When and How to Water

Watering your plant isn’t a one-size-fits-all task; it’s something that depends on various factors, such as the size of the pot, the quality of the soil, and the overall health of the plant.

• When: As a rule of thumb, water your Arrowhead plant when the top inch of soil becomes dry. This usually means watering approximately once a week during the growing season (spring and summer) and reducing watering to every other week during the dormant season (fall and winter).
• How: When watering, do so thoroughly until water starts to drain from the bottom of the pot. This ensures the roots receive enough hydration. Remember to discard any excess water sitting in the drainage tray to avoid waterlogging.

Signs of Incorrect Watering

Like any plant, your Syngonium podophyllum will display specific signs if it’s not being watered correctly. Here are some common symptoms to watch out for:

• Brown leaf tips: This could be a sign of underwatering or low humidity.
• Yellowing leaves: This is often a sign of overwatering.
• Wilting: This can be caused by both overwatering and underwatering—check the soil to determine the issue.

The Perfect Lighting Conditions

The Arrowhead plant is often classified as a low light tolerant plant, but it’s essential to understand what this really means. It doesn’t necessarily mean that it thrives in the dark or in the absence of light. Rather, it refers to the plant’s ability to tolerate and survive in less-than-optimal light conditions if needed. 

Indirect Lighting 

The Arrowhead plant thrives best in bright, indirect light (but can adapt to lower). Direct sunlight can scorch its leaves, causing them to turn yellow and fall off so be wary of direct sunshine during summer.

Artificial Lighting

If natural light is insufficient or inconsistent in your home, artificial lighting can be a good alternative. Fluorescent lights, for instance, can provide the necessary light spectrum for your plant. However, remember to keep the light source a few feet away from the plant to prevent leaf burn as Arrowheads can have very thin delicate leaves.

Low Light

While your Syngonium podophyllum can tolerate low light conditions, growth may be slower and the vibrant leaf colors may fade. Therefore, if you choose to keep your plant in low light, expect a less vigorous plant with muted colors.

Humidity and Temperature Control for Arrowhead Plants

The Syngonium podophyllum is a tropical plant that thrives in warm, humid environments. However, it also adapts fairly well to average home conditions which is why they can easily be kept as houseplants.

When it comes to temperature, Arrowhead plants prefer a range between 60-75°F (15-24°C). They are somewhat tolerant of lower temperatures, but any sudden temperature drops or exposure to cold drafts can harm the plant, causing leaf yellowing or even plant death.

Therefore, it is advisable to keep your plant away from external doors, windows, or other sources of cold drafts during the winter months.

As for humidity, Arrowhead plants love high humidity levels as it mimics their natural tropical habitat. A humidity level of 50% or higher is ideal.

If you notice that the leaves are turning brown on the edges, it could be a sign that your plant needs more humidity. To increase humidity you can mist your plant, use a humidifier or a pebble tray.

Tips for Fertilizing Your Syngonium

Understanding the Fertilizer Needs of the Arrowhead Plant 

Arrowhead plants are not heavy feeders, so they don’t require an excessive amount of fertilizer. Instead, these plants thrive best with a light, balanced fertilizer applied every 4 weeks during the growing season (spring and summer). During the fall and winter, remove fertilizer from your to-do list as these plants enter a dormant phase and fertilizing during this time will cause damage.

Choosing the Right Fertilizer

A balanced, water-soluble houseplant fertilizer, such as a 20-20-20 (N-P-K) mix, works well. This type of fertilizer contains equal parts nitrogen, phosphorus and potassium, the three main nutrients that plants require. These are pretty easy to find in plant shops and garden centers.

Applying the Fertilizer

Dilute the fertilizer in water according to the package instructions and then water the plant with this solution. Always apply the fertilizer to damp soil to avoid burning the roots. If the leaves of your plant start to yellow or brown at the tips, this could potentially be a sign of over-fertilization.

Consider Organic Options

If you prefer a more natural approach to plant care, there are several organic options available. Compost, worm castings, and seaweed extract are all excellent sources of nutrients that can help your Arrowhead plant grow. Remember to always follow the manufacturer’s instructions when using these products.

Repotting an Arrowhead Plant

Arrowhead plants need some occasional repotting to provide them with fresh soil filled with essential nutrients and a bit more space for them to grow. It doesn’t have to be a daunting process though as long as you handle your plant with care the whole way through.

When to Repot?

The best time to repot an Arrowhead plant is during the late winter or early spring, just before the start of the growing season. This gives the plant an opportunity to grow in fresh, nutritious soil and a bit more space. On average, an Syngonium podophyllum should be repotted approximately every two years but sooner if you spot signs your plant is rootbound.

Steps to Repot an Arrowhead Plant

1. Prepare the New Pot: Choose a new pot that is 2-3 inches larger in diameter than the current one. Make sure the new pot has drainage holes to prevent water logging.
2. Prepare the Plant: Water your Arrowhead plant one day before repotting. This ensures that the roots are hydrated and flexible, making the transition easier.
3. Remove the Plant: Carefully remove the plant from its current pot. Try to keep the root ball intact to minimize stress to the plant.
4. Place the Plant: Add a layer of fresh potting soil to the new pot and gently place the Arrowhead plant inside. The top of the root ball should be level with the rim of the pot.
5. Fill With Soil: Fill the rest of the pot with soil, firming it gently around the base of the plant. Ensure that the plant is secure but not packed too tightly.
6. Water the Plant: Thoroughly water the plant after repotting to help settle the soil around the roots.

Common Pests and Diseases and How to Prevent Them

Arrowhead plants, while generally robust and easy to care for, are not immune to certain common pests and diseases that can adversely affect their health and growth. Early detection, regular maintenance, and appropriate preventative measures can significantly reduce the risk of these problems. Below we delve into some of the common pests and diseases to help you diagnose any issues.

Common Pests

1. Spider Mites: These tiny pests can cause significant damage by sucking the sap from the plant. Indications of infestation include yellowing leaves and fine webbing. Regularly misting your Arrowhead plant can prevent these mites, as they prefer dry conditions.
2. Mealybugs: Mealybugs appear as small, white fluffy insects on the plant. They harm the arrowhead plant by feeding on its sap and excreting a sticky substance called honeydew. Wiping the leaves with a solution of mild soap and water can keep mealybugs at bay.
3. Scale Insects: Scale insects are small, round pests that attach to the plant and feed on its sap. They can be controlled by regularly wiping the leaves with neem oil or an insecticidal soap.

Common Diseases

1. Root Rot: Overwatering can lead to a condition known as root rot. This can be prevented by ensuring your plant has well-drained soil and is not left sitting in water.
2. Leaf Spot: Leaf spot disease causes brown or yellow spots on the leaves, often surrounded by a yellow halo. To prevent this, avoid getting the leaves wet when watering and ensure your plant has good air circulation.
3. Bacterial Blight: This is a serious disease that can cause wilting, yellowing of leaves, and stem rot. Prevention includes avoiding overhead watering, ensuring good air circulation, and removing and disposing of any diseased parts immediately.

Prevention is always so much better than a cure. Regularly inspect your Arrowhead plant for any signs of pests or diseases and start treatment as soon as you spot the signs.

Arrowhead Plant Toxicity

Human and Pet Toxicity

Arrowhead plants are classified as toxic to both humans and pets. The plant’s sap contains calcium oxalate crystals, which can cause skin irritation. If ingested, the effects can be more serious, leading to a burning sensation in the mouth, difficulty swallowing, and nausea.

First Aid Measures

If you or a family member come into contact with the sap of an Syngonium podophyllum, it’s important to take immediate action. Here are some initial steps to follow but we recommend you seek professional medical advice:

1. For skin exposure: Wash the affected skin thoroughly with mild soap and water. If irritation persists, seek medical attention.
2. For eye exposure: Rinse the eyes with lukewarm water for a few minutes, and then seek medical advice.
3. If ingested: Do not induce vomiting. Rinse the mouth with water and consult a medical professional immediately.

Flowers on an Arrowhead Plant

While not all varieties of Arrowhead plants will bloom in indoor conditions, those that do can grow beautiful small flowers that are very aromatic.

Timing and Conditions:

Flowering in Arrowhead plants typically occurs during the warmer months, particularly in summer and early autumn. However, the blooming cycle isn’t always predictable, and the exact timing may vary. The plant’s bloom often depends on specific conditions being met, such as ample sunlight, well-drained soil, and appropriate humidity levels.

Appearance:

When your Arrowhead plant decides to flower, you’ll notice small, spherical inflorescences appearing, covered in a multitude of tiny, cream-colored blossoms. These clusters, although not as showy as some other houseplant flowers, are still very pretty and smell great!

Post-Bloom Care:

Once the flowers have faded, it’s essential to trim off the spent blooms to encourage new growth. This practice, known as “deadheading,” not only keeps your plant looking tidy but also redirects energy towards leaf production and overall health.

Cleaning your Arrowhead Plant

Keeping your Syngonium podophyllum clean is not just a matter of aesthetics; it is a crucial aspect of plant health. Plants with clean leaves are generally healthier as they can effectively photosynthesize and breathe. Here are some steps to help keep your plant in tip-top shape:

1. Prepare your cleaning solution: You can use a mild, soapy water solution for cleaning. Avoid using any harsh chemicals that may damage the plant. Mix a few drops of mild dish soap in lukewarm water to remove tough dirt.
2. Wipe the leaves: Using a soft, damp cloth, gently wipe the upper and lower surfaces of each leaf. Be careful not to damage the leaves while wiping.
3. Rinse the leaves: After wiping, gently rinse the leaves with lukewarm water to remove any soap residue. Avoid using cold or hot water as it can shock the plant.
4. Let the plant air dry: Once you have cleaned and rinsed the leaves, let the plant air dry.
