Philodendrons always give a fresh and tropical look if grown with proper care. But it breaks our hearts when the plant becomes weak and mushy. And it is highly frustrating when we are unaware of the actual reason behind the plant’s weakness.

Leaves turning mushy is a major problem that you might notice in your philodendron. But, no need to freak out as you can fix it. This article will discuss the various ways to avoid and solve the problem of mushy leaves in philodendrons.

Overwatering is the primary cause of mushy leaves in philodendron. When overwatered, the roots suffocate in excess water, and the plant becomes weak, leading to mushy leaves. Lack of air circulation, pest attack, and insufficient light can also lead to mushy leaves in philodendrons.

It is not that hard to ensure the health of your philodendron. You just need to know the right things about the specific needs of your philodendron. Following the routine of any other plant might not be very helpful.

Weather fluctuations are not in our hands. But giving the right conditions inside the house is definitely in our hands.

What causes philodendron leaves to turn mushy?

Philodendrons are easy and fast-growing plants. They are forgiving and can tolerate all sorts of ignorance to a slight extent. But that doesn’t mean you should ignore it altogether. The philodendrons get affected due to living in an unsuitable environment.

We will read all the reasons for the cause of the mushy leaves in philodendron in detail to identify the leading cause for it in our plant.

1) Overwatering

Poor watering techniques can make the leaves of your philodendron mushy. When the leaves of your philodendron start turning yellow and mushy, it means you are giving your plant too much water. Overwatering can also occur due to an improper drainage system, resulting in root rot.

Check the drainage system of the pot. If the drainage holes get blocked, it won’t resolve the overwatering problem. To fix the problem, you must stop watering your plant until the soil dries up completely.

Overwatering can suffocate and damage the roots, for which the philodendron fails to absorb the nutrients.

You must take the philodendron out of the pot and prune the affected roots. If the damage is severe, your plant will require a new pot along with some fresh soil mixture.

Staying in the water for long can lead to root rot. It happens when you overwater your plant and don’t give the soil a chance to dry up. Another cause can be an improper drainage system. Overwatering affects the capacity of the plant to consume nutrients and moisture.

When you see that the leaves of your plant are turning soft and mushy, you know that your philodendron is overwatered.

Overwatering suffocates the roots and hinders their functioning. The leaves don’t receive the necessary nutrients, and you might get a foul odor from the soil because of root rot.

To revive your philodendron from root rot:

  1. Act immediately by repotting it.
  2. First of all, take out the whole plant slowly. You can use a knife for fast work.
  3. Remove the rotten roots that are brown and dark colored.
  4. Remove the mushy parts of the plant.
  5. Wash your plant.

Then take a new pot, put some fresh soil mix in it, and transfer your plant to that new pot.

Do not use the old soil, as it may get attacked by fungus and bacteria due to root rot. Root rot can invite all sorts of pests and fungi. So, it is better to dispose of the old soil and use fresh soil for repotting.

2) Pest infestation

Mushy leaves in philodendrons can develop due to unwanted guests like spider mites, mealybugs, aphids, thrips, and many more.

If your philodendron is overwatered, it creates a perfect environment for these pests who make the plant weaker. The leaves of the plant can droop and become mushy out of weakness.

These are sap-sucking pests. They suck all the sap from all parts of the plant, making the plant flaccid. You will even notice distortions and irregularity in its growth.

These pest infestations can even cause further damage, like inviting harmful viruses and fungal infections. Powdery mildew is one of them.

To get rid of pest infestation, you can buy repellents from the market. 

Homemade remedies are the best options as they are natural and chemical-free. Consider using neem oil against these attacks.

Use soap and water to clean the plants and remove all the fungus and pests. After that, spray some neem oil. Don’t wash off the oil. After that, keep them in a place where they will get proper airflow.

3) Inadequate light

Philodendrons need the proper light to remain healthy. If they don’t get adequate light, then healthy growth of philodendrons won’t take place.

Philodendrons can survive in low light, but that doesn’t mean they don’t need light at all. Being tropical plants, they enjoy the warm and tropical atmosphere around them. If they don’t get sufficient light, the soil will not get a chance to dry up properly, leading to overwatering.

Philodendrons grow best in indirect sunlight. They don’t need too much light, as the correct duration of indirect light works well for their growth.

If you’re growing philodendrons indoors, keep them somewhere near the window in such a way that they can get the warmth of the sun, but the direct light of the sun must not touch the leaves. Or you can use curtains as a filter. Older leaves may turn yellow due to little heat.

If you’re growing philodendrons outdoors, keep them in a shady place where they can get both the warmth of the sun and indirect sunlight with adequate airflow.

4) Pot size

The pot size for your philodendron relies on the size of your plant. 

 If the pot size is bigger than your plant, that can lead to overwatering, causing damp soil, which is unfavorable to philodendrons.  

For better results, you can repot your philodendron according to its size. When you see your philodendron growing bigger, change the pot. Take a bigger pot and transfer your plant into that pot.

Or, you can cut down your philodendrons and propagate them again.

By this, you can save your philodendron’s leaves from turning mushy.

5) Wrong potting soil

The soil plays an important role in determining the health of all houseplants. If you make the wrong soil choice, you will see the results on your plant.

Philodendrons need a well-draining soil mix that can hold some moisture. Philodendrons don’t enjoy sitting in soggy or extremely dry soil, so you need something in between.

If you use a regular potting mix for your philodendron, it will be too heavy and will hold excess water that will make the leaves mushy. You must add some chunky elements to make the soil well-draining.

6) Lack of air circulation

Placing your philodendron in an area that doesn’t receive good air circulation will lead to different problems, including mushy leaves.

Lack of air circulation doesn’t let the soil get dry due to which it remains wet for longer than required. The soil and roots don’t get any airflow, which worsens the problem.

You must find a spot for your philodendron that not only receives indirect light but also gets proper air circulation.

How to prevent mushy leaves in philodendron?

  • You can use homemade fertilizers, horticulture oils, and pesticides. They are completely natural and chemical-free.
