One common mistake even seasoned indoor gardeners make when growing Monstera plants is related to watering.

Both overwatering and underwatering can cause problems with your plant’s health.

Symptoms of Overwatering

Overwatering is a more serious issue than underwatering and is often a more frequent problem.

Some signs of an overwatered Monstera are:

  • Yellowing leaves
  • Soft, mushy stems
  • Root rot
  • A moldy or musty smell

Overwatering can be caused by watering too frequently, especially during the plant’s dormant period.

Other factors contributing to this problem include heavy, poorly drained soil, oversized pots, or a lack of drainage.

To prevent overwatering, make sure the pot has drainage holes and that the soil is well-draining.

Monitor your plant’s water needs and adjust your watering schedule accordingly.

Symptoms of Underwatering

Underwatering is less detrimental to your Monstera plant than overwatering, but it can still harm the plant.

Some indicators of an underwatered Monstera include:

  • Dry, crispy leaves
  • Wilting or drooping foliage
  • Slow or stunted growth
  • Browning leaf tips

Underwatering can occur when there’s not enough water being provided, or when the soil dries out too quickly.

To ensure proper moisture levels for your Monstera, water the plant until water flows out of the drainage holes, and allow the soil to drain fully before emptying the drainage tray.

It’s important to be mindful of your plant’s water needs and adjust your watering schedule based on its requirements.

2. Inadequate Humidity and Temperature

Monstera plants are native to tropical regions, and they require a certain level of humidity and temperature to thrive.

Ideally, a Monstera’s humidity should be within the 40-60% range, and the temperature should stay between 60 to 85°F.

When these conditions are not met, the plant’s growth might slow down or even halt.

Low humidity may cause the stomata (pores) on the leaves to close, affecting the plant’s ability to undergo photosynthesis.

This can lead to yellow or brown leaves, and the plant may appear wilted or droopy.

On the other hand, excessive humidity can result in mold growth, which can damage the plant.

Providing Optimal Climate

To maintain the optimal climate for your Monstera, here are some tips you can follow:

  • Keep the indoor temperature consistently above 60°F (16ºC), ensuring that your Monstera can grow healthily at all times.
  • Use a humidifier to maintain the recommended humidity range. Alternatively, you can mist your Monstera daily with water to increase humidity around the plant.
  • Place your Monstera near a bright window but avoid direct sunlight, as this can cause the temperature to rise too high. Ensure that there is adequate airflow.
  • Group your Monstera with other plants in your indoor garden to create a more humid microclimate.

By providing the right humidity and temperature conditions, you will create a more comfortable environment for your Monstera.

3. Improper Lighting

Monstera plants need bright, indirect light to thrive, but too much direct sunlight can lead to problems.

Finding the right spot where your plant receives just the right amount of light will help your Monstera grow without having to change its position and location often.

Too Much Light

Excessive direct sunlight can dehydrate the leaves and even cause them to burn, resulting in yellowed or brown edges, wrinkling, or curling.

When Monstera leaves are exposed to too much heat from direct light, they become stressed, which affects their ability to make the energy needed to stay firm and sturdy.

To avoid this, find a spot in your home with bright, indirect light, or invest in an indoor grow light that allows you to control the amount and intensity of light.

Keep in mind that incandescent bulbs tend to get hotter than LED bulbs, increasing the risk of burning your Monstera, so it’s best to use LED grow lights for better temperature control.

Not Enough Light

On the other hand, inadequate light can also harm your Monstera plant and stunt its growth. It’s important to provide 10 to 12 hours of bright, indirect lighting every day.

When there’s insufficient sunlight during winter or when the room is too dark, grow lights become instrumental in supplying your Monstera plant with the necessary light.

Keep track of your Monstera’s daily light exposure, and adjust your lighting set-up accordingly to ensure its health and growth.

Remember that it’s all about finding a balance between too much and too little light, which can differ depending on the specific conditions in your home.

4. Poor Soil and Drainage

Selecting the Right Soil Mix

One common mistake when growing Monstera is using low-quality or poorly amended potting soil.

This can lead to yellowing leaves, weak stems, and droopiness in your plant.

The ideal soil for Monstera should be rich in nutrients and retain moisture without staying waterlogged.

Using a peaty potting soil that retains water but is also well-draining is crucial for maintaining optimal soil conditions.

Improving Drainage

Proper drainage is essential to avoid overwatering, root rot, and leaf damage in your Monstera.

Choose a pot with drainage holes, and ensure that the soil you use allows excess water to escape easily.

Some tactics to improve drainage include:

  • Adding perlite or sand to your soil mix – These materials can help create air pockets within the soil, promoting good drainage and preventing waterlogged conditions.
  • Layering pebbles at the bottom of the pot – Placing a layer of pebbles or coarse gravel below the soil can increase drainage and allow excess water to pool away from the roots.

Remember that Monstera plants typically grow well even in small pots compared to the size of their leaves. They thrive when their roots have enough room to spread out but are still contained.

5. Lack of Nutrition

Providing proper nutrition not only encourages growth but also helps Monstera plants fend off pests and diseases.

Here we’ll discuss the most suitable fertilizers for Monsteras and the appropriate feeding schedules to ensure that your Monstera thrives in both indoor and outdoor environment.

Choosing the Right Fertilizer

Selecting the appropriate fertilizer for your Monstera is essential to ensure healthy growth.

Monstera plants prefer a balanced, slow-release fertilizer with equal amounts of nitrogen, phosphorus, and potassium.

You can opt for an aroid-specific fertilizer or use a balanced 20-20-20 liquid fertilizer diluted to half-strength.

It’s also beneficial to include trace elements such as magnesium and iron, as these nutrients contribute to the plant’s overall health and vibrant green foliage.

Always follow the manufacturer’s instructions and avoid over-fertilizing, which may lead to salt buildup and potential root burn.

Frequency of Fertilization

The frequency of fertilization is crucial in maintaining the health of your Monstera.

These plants have a distinct growing season in spring and summer, during which their nutritional needs increase.

During this period, aim to fertilize your Monstera once a month. You can adjust the schedule based on your plant’s growth rate and specific needs.

In the colder months, Monstera plants often enter a dormant phase, which means they need less frequent feedings. During this time, reduce fertilization to once every 2-3 months.
