Pink Syngonium Plant Care – Growing Pink Arrowhead Plant

The Pink Syngonium is also known as the Pink Arrowhead Plant. It is a beautiful plant that features pink foliage.

But when people talk about the Pink Syngonium, it is not limited to one specific plant. Instead, there are a few Pink Syngonium varieties.

All of them have pink leaves. But the amount of pink hue can vary from the entire leaf to just the veins.

Here are some of the well-known Pink Syngonium varieties.

  • Syngonium Neon
  • Syngonium Pink Splash
  • Syngonium Robusta
  • Syngonium Red Heart
  • Syngonium Mickey
  • Syngonium Confetti
  • Syngonium Mango Allusion
  • Syngonium Strawberry Ice
  • Syngonium Pink Flecked
  • Syngonium Red Spot

Of course, when it comes to growing this stunning plant, one of your main goals to is maintain its gorgeous pink colors.

How do you care for the Pink Syngonium? It needs plenty of light, ideally bright, indirect light. Avoid excessively intense light as this can make foliage fade or even burn it.

Also, keep it away from low light spaces as this can make the pink leaves revert back to green.

The plant needs high humidity and a warm environment as well.

Pink Syngonium Plant Care

Pink Arrowhead Plant Light Requirements

The Pink Syngonium needs medium to bright, indirect light o maintain its beautiful pink leaves. This is essential as the amount of light the plant gets affects the color of the foliage.

Ideally, keep the plant near an east or west facing window.

The east is where the sun rises and the plant will receive plenty of morning light there. Meanwhile, the west is where the sun sets. This gives the pink arrowhead plant late afternoon sunlight.

Both are ideal because the sun’s rays are not intense during this time.

On the other hand, be careful with excess direct sunlight.

While the Pink Syngonium will have more pink hues and vibrant leaves with good lighting, too much harsh or strong light will cause its color to fade.

In extreme heat and intensity, the rays can likewise scorch the leaves.

So, avoid direct sunlight during the middle of the day. This comes from the south.

If you want to place the plant towards the south, keep it at least 3 feet from the window.

On hter other hand, the Pink Syngonium is known for being low light tolerant. But while the plant won’t have any issues with low light, the leaves will.

Low light will cause the leaves to become less pink and more green.

This happens because the plant needs to absorb more light for photosynthesis. To do so, it will produce chlorophyll which is the substance that collect light. It also happens to provide the green pigment for leaves.

So, the more chlorophyll the plant produces to get more light, the greener the leaves get.

Therefore, your Pink Syngonium’s leaves will lose their pink hues and revert to green.

This is why I highly suggest avoiding low light for the Pink Arrowhead Plant.


Pink Arrowhead Plant Temperature

The Pink Arrowhead Plant thrives in temperatures between 60 and 80 degrees Fahrenheit.

It likes this condition because that’s what it receives in its natural habit, the tropical forests of South America.

However, it can tolerate conditions slightly above and below this range as well.

This wide range of temperatures makes it easy to grow the plant indoors.

But note that the Pink Syngonium is not well-suited for the cold. It can only withstand temperatures down to 50 degrees Fahrenheit.

Once it gets colder than that, the plant will struggle.

You’ll see this initially with slow growth. After a while, the color of its leaves will change and they will eventually drop.

If you keep the plant in this environment for a long time, it can suffer cold injury. Eventually, it can die as well.

Thus, don’t leave it outdoors during the winter. Instead, bring it indoors and keep it warm.

Similarly, avoid placing it near air conditioners or spaces that experience cold drafts.

That said, the plant does well outdoors in USDA Hardiness Zones 10 to 12. These locations have warm weather even during November through March.

As such, the Pink Arrowhead Plant has no issues growing outside.



The Pink Syngonium enjoys high humdiity, ideally between 60% and 90%. As long as you keep humidity in the 60% to 70% range, the plant will be happy.

It can likewise tolerate humidity of 40% to 60% which makes it somewhat easier for most home growers.

I say somewhat because many homes have humidity between 20% and 50%.

So, the lower range may or may not be normally achievable without any intervention of you part.

You also want to be careful about air conditioners, heaters and radiators since these appliances tend to dry the air.

Similarly, dry summers can cause big drops in humidity.

And winter is well-known for very dry air.

Therefore, it is a good idea to check the changes in humidity when the seasons change. You can use a hygrometer to do this.

If humidity indoors is too low, you will see the leaf edges and tips of the Pink Arrowhead Plant become brown and dry. They will get crispy and brittle as well.

This is a sign that the plant needs more humidity.

You can mist the plant a few times a week, move it to the bathroom or set it on top of a pebble tray.

Alternatively, you can likewise pick up a humidifier.




How Often to Water Pink Syngonium

The Pink Syngonium enjoys slightly moist soil on a consistent basis. It does not like wet soil nor does it like going dry.

As such, it is important to find that balance in between.

The common pitfall here is to try to keep the plant well-watered at all times. I’ve found this to be risky as you’ll usually end up leaving to soil wet.

Unfortunately, overwatering can lead to root rot.

This makes watering more often more dangerous than slightly underwatering the plant.

That’s because it has no issues with the latter unless you let the soil go dry. As long as this does not happen or you quickly water it once you discover this, it isn’t problematic.

As such, the best way to avoid this is to wait until the top 2 inches of soil has dried.

I prefer to wait until the top half of the soil is dry before adding more water. And I know a few fellow gardeners who wait until 3/4 of the soil dries.

Any of these work well.

As long as you’re in between this range, you can prevent overwatering as part of the soil has already dried.


Pink Syngonium Potting Soil

The Pink Syngonium needs well-aerated soil with good drainage. It also prefers soil pH of 5.5 to 6.5.

Good drainage and aeriation are important because of the plant’s sensitivity to overwatering.

Soil plays a large part in this because in addition to when you water, the kind of soil affects what happens to the water in the substrate.

This means that even if you water correctly, if the soil retains too much of the moisture, the roots still end up sitting in water for long periods of time.

As such, avoid heavy soils of those that tend to hold water.

Instead, go with well-draining soil for this plant.

If you don’t like to make the potting mix yourself, you can go to your favorite nursery or online plant store and pick up a bag of Aroid mix.

This works really well for the plant. It is loose, well-draining and allows for good air circulation to let the roots breathe.

On the other hand, if you’re like me, you can create your own DIY potting mix for the Pink Syngonium. Here’s a simple one that works well.

  • 1 part potting soil
  • 1 part perlite
  • 1 part orchid bark

The final piece of preventing overwatering is to use a pot with drainage holes.

This will allow excess moisture that drains from the soil to get out of the pot. This way it does not just accumulate at the bottom which will keep the soil wet.


Does the Pink Syngonium Climb?

A healthy Pink Syngonium will start vining at some point. That’s because this is how it grows in the forest climbing up tree trunks.

As such, it is a good idea to give the plant a pole or support to climb on.

Doing soi will let it grow taller. And the leaves will come out from the center.

However, I know many growers who prefer to keep in it a pot. If you do, the plant will get bushy and stubby.

This is a great look as well. But it will mean more pruning as the plant will get “fluffy” looking. It can also get top heavy and start to droop.


Pink Arrowhead Plant Fertilizer

The Pink Syngonium will grow faster with fertilizer. Giving it sufficient nutrients not only allows it to grow bigger but also lets it produce more leaves.

Therefore, feed the plant using a balance fertilizer every 2 to 4 weeks during its growing season.

This is when it does most of its growing.

Also, dilute the fertilizer to half strength each time you apply.

You can likewise use slow-release fertilizer which works well. This reduces the application frequency on your part.

Slow-release fertilizer come in pellet form that will dissolve over time.

So, you’ll be distributing the fertilizer instead of applying it a s liquid (in the case of the balanced formulation above).


Pink Arrowhead Plant Pruning

The Pink Syngonium can grow to 3 to 6 feet if you allow it climb. This is when it will grow the tallest.

In contrast, without a support or pole to go up on, the plant will usually get to about 1.5 to 2.5 feet high. Here, it will look more like a bushy clump as it gets full.

As such, the look of the plant and how its size varies a lot depending on how it grows.

That said, the Pink Arrowhead Plant is a fast grower.

Additionally, it is easy to propagate.

This is why many growers like this plant.

As far as pruning goes, you will likely need to prune every now and then at least. A healthy Pink Syngonium grows quite fast.

And if you don’t let it climb, it get thick and bushy. Thus, it needs trimming every so often.


How to Propagate Pink Syngonium

One of the best things about the Pink Syngonium is it is easy to propagate. This is great considering that it is a very beautiful plant.

As such, you can grow more of this plant without buying it from the store.

In fact, you can propagate it at home for free.

The simplest way to propagate the Pink Syngonium is by stem cuttings. And it will propagated in water just a well as it does in potting mix.

This give you a couple of options on how to root the plant.

The most important thing when propagating the Pink Syngonium is taking the stem cuttings. Make sure you choose healthy stem cuttings with at least one node and 2 or more leaves.

Once you have this, you’re just about halfway done. Next:

  • Cut the chosen stem cuttings just below the node. Sanitize the blade first to ensure you don’t pass any pathogens from the cutting tool to the plant.
  • Let the cutting sit for about an hour. This will give it time to callous.
  • In the meantime, prepare a pot and fill it with well-draining potting mix.
  • Then apply, rooting hormone to the cut end of the stem and plant it into the soil mix.
  • Keep the pot in bright, indirect light. A warm humid spot is perfect.

It will usually take about a month for the roots to develop.

On the other hand, you can likewise propagate in water.

Here, place the cutting in a jar with water. Submerge the nodes in the liquid. Then leave the jar in a well-lit location with no direct sunlight.

In a few weeks you’ll see roots developing.

Once the roots get to about 1-2 inches long, you can transfer them from water into potting mix.


How to Repot or Transplant Pink Syngonium

The Pink Syngonium only needs repotting every 2 years. But don’t just strictly follow this figure.

Instead, use it as a guide.

You’ll know when to repot the plant once you see some roots showing up through the holes at the bottom of the container.

Additionally, the plant’s grow with slow down or stunt.

That’s because its roots are overcrowded in the pot and it feels uncomfortable.

The best time to repot is during spring to early summer.


Is It Toxic/Poisonous to Humans, Cats & Dogs

Unfortunately, yes. The Pink Syngonium contains calcium oxalate crystals that will cause inflammation when parts of the plant are ingested.

Therefore, it is important to keep it away from young kids, cats and dogs since they can accidentally eat the plant’s leaves or stems.


Pink Syngonium Problems & Troubleshooting


The Pink Syngonium is resilient to pests. However, this does not mean that it is immune.

While there’s less likelihood of pests attacking it, it could still happen.

The most common pest that will bother this plant including aphids, spider mites, scale and mealybugs. These are all sap sucking insects.

While small they can inflict a lot of damage because they grow in number fast.

Therefore, you need to regular check the Pink Arrowhead Plant for any bugs, especially under the leaves where these insects like to hide.

If you spot any, treat them with neem oil or insecticidal soap. You can also use chemical insecticides. Although I prefer to use natural products.



Stem rot, root rot and leaf diseases can happen to this plant. While they don’t happen often, they can occur especially if the plant is not given the right care.

Overwatering is the most common cause of these problems.

It can lead to rotting which can eventually kill your plant if not treated early enough.

On the other hand, wet leaves that don’t dry quickly results in leaf infections. These can be bacterial or fungal.

So, try not to water the plant overhead which gets the leaves all wet.
