Why Are My Syngonium Leaves Not Unfurling? (And How To Fix)

There are many Syngonium plants with different shapes and colors of leaves. However, when the leaves are struggling to unfurl, they are usually lacking in what they need. Because Syngoniums are tropical plants, they also work similarly to other plants native to their area, including Gloriosum and Monstera. This means they all have a few similar options; you can try to see if they will unfurl as they should. 

Syngonium leaves may not be unfurling due to a lack of humidity, cold temperatures, not enough sunlight, or your plant may need fertilizer or water.  

Sometimes, leaves are just slow to grow as well. Trying to unfurl a plant’s leaves is a bad idea as the leaf may grow improperly and cost your plant more energy. Leaves that are curling and leaves that won’t unfurl are not the same, though their missing habitat element may be similar. 

How Long Do Leaves Take to Unfurl?

How long it takes a plant’s leaves to unfurl depends on the plant. Monsteras can take a full two or three weeks. If Syngoniums are stressed, they can stay curled up for up to a month. 

This means that if your plant seems to be taking a long time to unfurl, don’t be too worried. You may need to wait at least a month to ensure your plant isn’t taking its time. Sometimes, they may not be getting the right amount of something they need. 

Syngonium leaves, for example, need enough moisture before they can unfurl their leaves. If their air isn’t humid enough, or they aren’t getting enough water, it will take longer for your plant to straighten out its leaves. 

Should You Help a Leaf Unfurl?

It is not a good idea to help a plant’s leaves uncurl with physical movements. While you can add more moisture or sunlight to their environment, physically unfurling their leaves can injure the plant and cause the leaf itself to have stunted growth or turn brown. 

You will have to find other ways to benefit your plant and allow them to unfurl its leaves themselves. 

Why Do Syngonium Leaves Curl Up?

If your plant isn’t having problems unfurling as it grows but is instead curling up, that may be a sign the plant is not in a suitable habitat. 

Curling is usually associated with problems such as low humidity, improper watering, too much direct light, insufficient nutrients, temperatures that aren’t ideal, and too many nutrients. 

If you want your leaves to stop curling up, you will have to adjust their environment to fit their specific needs. 

Why Won’t My Plant Leaves Unfurl?

Usually, if your plant isn’t unfurling its leaves, even long after they should be, that is often a sign that something is wrong. You never want to manipulate your plant leaves physically, but there are other steps you can take. 

How Do You Get Syngonium Leaves to Unfurl?

Syngonium leaves have a few reasons why they may not unfurl. The most common cause is a lack of humidity. If a Syngonium doesn’t have enough mature leaves, it may not have enough energy from the sun to finish unfurling new leaves.  

The second most common reason is that the plant may not get enough sunlight. This is a common problem with many pink varieties of Syngonium, as their leaves need a lot of sunlight to keep their color and to unfurl in the first place. 

Other problems, though not as common, that cause plants to be unable to unfurl are a lack of nutrients and not enough water. Sometimes, plants may be placed in too big of a pot. When that happens, they may not get the water they need as their roots aren’t long enough to reach the bottom where all the water settles. 

Syngonium doesn’t need a lot of fertilization either, but when they grow quickly, a little liquid fertilizer can help ensure they don’t burn through their nutrients with their rapid growth. 

Fixing these problems will help your plants’ leaves unfurl without damage. Though it may take longer, it is less harmful to your plant than when you try to unfurl the leaves on your plant manually. 

How Do You Encourage Leaves to Unfurl?

Giving your plants a bit more humidity with a light misting and giving them more bright but indirect light are the two best ways to encourage your leaves to unfurl. It doesn’t matter what kind of plant it is. A little more sunlight and humidity are your two best options with most plants. 

Additionally, if it is a little cool for your plant, keeping it in a warmer area can help it to grow a bit more. If a plant is too cold, it can struggle to grow as fast as it would if it were warmer. 

How Do You Know if a Leaf Is Stuck?

Sometimes, leaves can get stuck in a cataphyll. This makes it tricky to know how to help your plant, as physically helping them can cause damage, even if you are gentle. 

First, you need to determine if your leaf is stuck. Usually, the leaf will be frozen in what seems to be a bent and awkward angle. They will also look like there is a sheath covering the plant.

Not all plants risk getting stuck in a cataphyll, but plants like Syngoniums and Philodendrons do. 

Even when stuck, helping a plant release from the sheath will only cause damage. The leaf can become deformed or even injured, no matter what method you try or how gentle you are. While not every single leaf will be deformed, there is a very high risk of it happening. 

You want to follow the same guidelines even when your plant’s leaf is stuck inside a cataphyll. You want to increase humidity and sunlight around your plant to encourage the leaf to unfurl or get unstuck. 

Why Is My Gloriosum Leaf Not Unfurling?

Like most plants, if a Gloriosum leaf isn’t unfurling, it is likely due to humidity or moisture of the soil. For an immediate fix, you can mist your plant’s leaves once or twice a week. If this is common, you can make a pebble tray or buy a humidifier.

Since Gloriosum is a tropical plant, humidity is something these plants often lack, especially indoor plants. 

Why Is My Monstera Leaf Not Unfurling?

Like other tropical plants, Monstera leaves often struggle to unfurl when there isn’t enough humidity in their environment. Although Monstera can survive on lower humidity than it likes, it will often struggle with growth and new leaf development. 

To provide your plant with the humidity it needs, mist it once or twice a week. This will not only help your new leaves but your established leaves as well. 

You can also ensure your plant is in a warm room with lots of indirect sunlight. Monsteras need a lot of light, though they don’t like direct light. They also need a warmer environment to grow. 

However, it is essential to remember that Monsteras have fairly large leaves that take a lot of energy to grow. Your Monstera’s leaves won’t naturally unfurl in a few days; instead, it could take several weeks. Even if your plant is very healthy and in an ideal environment, Monsteras take a long time for their leaves to unfurl fully. 

For this reason, it is good to remember to be patient. Sometimes, plants just struggle with a leaf or two or don’t have enough energy to finish the leaf all at once. That doesn’t mean something is wrong and is, in fact, a natural process. 


Generally, when Syngonium leaves are not unfurling, it is either due to a lack of humidity, cold temperatures, or not enough sunlight, or your plant may need fertilizer or water.  

Many tropical plants, including Syngoniums, Monsteras, and Gloriosums, need plenty of humidity, warmth, and sunlight to help their leaves unfurl. They will often struggle to unfurl their leaves if they don’t have these requirements. This is because the humidity helps loosen the leaves while the sunlight and warmth ensure your plant gets the proper energy it needs and that all systems work at their best. 

Sometimes, even in ideal conditions, some leaves will struggle to unfurl. When that happens, be patient. No matter what, don’t try to unfurl your plant’s leaves physically. It can cause deformity and damage to your plant, no matter how careful you are.
