5 Reasons Your Monstera Leaves Are Turning Yellow & How to Fix It

Reasons for Yellow Monstera Leaves

In caring for your Monstera plant, you may sometimes encounter issues with yellowing leaves.

Let’s bring these leafy giants back to their vibrant health with some plant-loving pep!

The following are common reasons for this issue and ways give it back its old charm.

1. Over-Watering

Drowning our green pals in H2O is a classic blunder – we mean well, but in reality, we’re causing our Monsteras some serious waterlog problems.

Here’s how we can make things right:

  • Check the moisture in the soil. If it’s constantly wet, you need to cut back on watering.
  • Ensure your pot has proper drainage to prevent water buildup in the soil. Without proper drainage, we’re setting the stage for root rot.
  • If the plant has been overwatered, let the soil dry out before watering again.

2. Under-Watering

Just like over-watering, under-watering is another extreme we want to avoid because it can also cause yellow leaves.

Monsteras need consistent moisture to thrive. When they don’t receive enough water, the older leaves can turn yellow.

If underwatered, water your plant more frequently to maintain consistent moisture levels.

To remedy this:

  • Establish a regular watering routine. Monsteras love consistency!
  • Allow the top 1-2 inches of soil to dry out between waterings.
  • Assess the moisture level in the soil before watering to avoid drought stress. Feel the soil before watering. If it’s dry and dusty, it’s high time for a water party!

3. Inadequate Light

Monsteras thrive in bright, indirect light. Insufficient lighting can cause them to produce yellow leaves. To optimize light conditions:

  • Scout for a spot that gifts your Monstera plenty of natural light without the risk of sun burnt leaves. Just enough to keep them radiantly joyous, not sun-stressed!
  • Ensure that your Monstera isn’t caught in direct sunlight, as this can scorch its leaves.
  • Consider investing in a grow light, especially in the gloomier winter months or if your place is more like a cozy cave than a sunlit loft.

4. Nutrient Deficiencies

Yellowing leaves can also be a sign of nutrient imbalances or deficiencies in your Monstera. Correcting these can help prevent further yellowing.

But don’t overdo it, as too much fertilizer can cause leaf burn and yellowing.

Let’s get those essential elements back into the game:

  • Treat your Monstera to a balanced liquid fertilizer once a month during the growing season. Think of it as their monthly spa treatment!
  • Apply a balanced fertilizer, such as 10-10-10, to supply essential nutrients like nitrogen, phosphorous, and potassium. Follow the manufacturer’s instructions for the recommended frequency and application rate.
  • Monitor for symptoms like yellowing between leaf veins, as this could be a sign of magnesium (Mg) or other micronutrient deficiencies.

5. Pests and Diseases

Pests and diseases can be party crashers, sucking the life out of your Monstera and turning leaves yellow.

Common pests like spider mites, mealybugs, and aphids can drain nutrients from your plant, causing yellowing.

The same goes for diseases like bacterial or fungal infections. Here’s how to pacify the chaos:

  • Regularly inspect your Monstera for signs of pests or disease. It’s like a mini health check for your leafy friend!
  • If you do spot pests, arm yourself with a suitable pesticide or go the green route with a natural remedy. Either way, it’s time to show those bugs the door!
  • A well-ventilated area with the right humidity levels is like a fortress against fungal growth. Let’s ensure our Monsteras are living in a breath of fresh air!

This video has a few great tips on how to treat pests for your indoor Monsteras.

Yellowing Prevention Tips

An ounce of prevention is better than a pound of cure, so when planting your Monstera for the first time, make sure they are in the right environment from the beginning.

Use Well-Draining Soil

Using well-draining soil is essential to keeping your Monstera healthy and preventing yellow leaves. A good mix of soil should retain some moisture, but not become soggy.

To create a well-draining soil mixture, combine potting soil with perlite, coco coir, or orchid bark to increase drainage and aeration.

This helps prevent root rot and promotes healthy root growth for your Monstera.

Choose the Right Container

Selecting an appropriate container for your Monstera plant is crucial for avoiding yellow leaves.

Look for a pot with drainage holes to prevent water from becoming stagnant at the bottom, which can lead to root rot.

Additionally, choose a container that is the proper size for your plant – not too small to restrict root growth, but not too large to cause moisture retention issues.
