Monstera Deliciosa is also termed as the ‘Swiss-cheese plant.’ It is typically grown as a houseplant in regions that lie at mid-latitudes. The plant is a member of the Araceae family and can grow up to 65 feet (20 meters) in tropical forests.
With its lush green, large leaves, this tropical plant elevates the outlook of your garden. However, improper care and negligence can cause its stem to brown and wilt.
Why Does My Monstera Deliciosa Have A Brown Stem?
The most likely chances are that your plant has undergone stem rot. Overwatering or improper drainage can cause the stem to be brown and get infected. To fix a stem rot, remove the plant from the pot, and wash the roots. Ensure that your plant does not get waterlogged by watering it only when the topsoil appears dry. Though treatable in the early stages, stem rot can kill your plant if immediate actions are not taken. Not all brown parts on a stem are a bad sign. Stems become woody and appear brown. Furthermore, foliar shears, this is where a leave emerged from your Monstera Deliciosa, are also brown. This is absolutely normal and no reason to worry.
How to Take Adequate Care Of Your Monstera Deliciosa Plant?
Monstera Deliciosa can prove to be a lovely addition to your home. But to sustain their mesmerizing appearance, adequate plant care is imperative.
Grow your Monstera Deliciosa plant in a room with a temperature of 77 to 85 Fahrenheit degrees (25 to 30 degrees Celsius). Position the plant in an area with bright indirect light.
The most important thing to consider while planting Monstera Deliciosa is to avoid overwatering.
Make sure that your pot contains drainage holes. And, only water the plant when the roots have absorbed all water, and they seem moisture-free. To ensure proper growth, fertilize your plant at least once a month.
Causes of Brown Stems on Monstera Deliciosa Plants
The most common causes for brown rotting stems on Monstera Deliciosa plants are listed below.
Monstera plants are prone to fungal diseases. Fungus like to grow in wet places, and hence overwatering your plant can promote its growth.
Most people make the common mistake of following a routine for watering their plants without testing the soil for its dryness. This causes the soil to become soggy and the stem to rot.
A better approach is to monitor the dryness of the soil closely. And, water your Monstera plant only when the stem and topsoil seem almost completely dry.
As stated before, it is essential that you plant your Monstera Deliciosa in a pot with drainage holes. This way, your soil will not get waterlogged.
Waterlogged soil leads to a shortage of oxygen for the plant. Insufficient oxygen levels and excess humidity induce the growth of pathogens like fungi and bacteria.
Poor Quality Soil Mix
If the soil mix is not properly drained, your stem will develop rot eventually. A low-quality soil mix has many pores that cause it to retain water for an extended time period.
Thus, even if you are watering your plant with care, stem rot cannot be avoided until the soil mixture is replaced.
Excessive Use of Fertilizer
Though fertilization is helpful for healthy plant growth, excessive use is harmful. Over-fertilizing the soil leads to a large amount of salt accumulation. The soil becomes saline and vulnerable to pathogen attacks.
It is recommended to fertilize your plant once a month during summer and spring.
Improper Temperature Conditions
Monstera Deliciosa requires an optimum temperature for proper growth. However, if the temperature drops very low, the soil starts to stay moist for a longer time.
The soil will eventually develop fungus, causing the stem to brown and rot.
How to Treat a Monstera Deliciosa Stem Rot?
As soon as you notice the color of your plant’s stem darkening, remove the plant from the soil. Place it below the tap, and wash the roots properly with soap water.
Clean the pot with a disinfectant, and fill it with a new soil mix.
There are specific ways to deal with a Monstera Deliciosa with stem rot. You must cover your hands with gloves and use tongs to wash the roots and stem.
Try to cut out all affected regions on the stem and leaves. You can do so by slicing the midrib and slowly moving towards the infected areas.
If you wait for the darkening to continue, chances are the rot will spread. And, your plant will die soon.
While washing the roots, handle them with care as they are delicate. In addition to this, cut out the adventitious roots that are fully rotted. Once the roots have been properly washed and the pot rinsed, the plant is ready for regrowth.
However, it is vital to ensure that such a situation does not arise in the future. To avoid stem rot from happening again, you will have to closely follow the soil’s moisture level.
There are several methods to know if your plant requires watering.
- Gently dig your index finger deep into the soil (just above the bottom root). If the soil is entirely moisture-free, then this is a sign for you to water it.
- Make use of a wooden stick. To keep your hands clean (and avoid any risk of getting the fungal infection on your fingers), you can probe the soil with a stick. In case your stick becomes moist after insertion, you should not water your plant.
- Buy a moisture meter. Technology has led to the development of more convenient methods for us. A moisture meter is a device that accurately measures the moisture level of the soil.
Tips To Avoid Browning of Stem
- Use a soil mix that is chunky
- Ensure that the stem is not buried by soil
- Strictly avoid overwatering the soil.
