19 Common Problems With Round Leaf Calatheas

When it comes to houseplants, round leaf calatheas are some of the most captivating and unique additions you can have in your home. Their vibrant patterns and lush foliage can transform any space into a green oasis. However, these beauties can sometimes be a bit finicky, leaving plant parents scratching their heads over what went wrong.

In this article, we'll explore 19 common issues faced by round leaf calatheas and how you can address them. From droopy leaves to mysterious spots, we'll cover everything you need to know to keep your calathea healthy and thriving.

1. Drooping Leaves

One of the first signs that your calathea might not be happy is drooping leaves. This can be caused by several factors, and it's essential to identify the correct one before taking action.

Firstly, check the soil moisture. Calatheas are particular about their water needs. If the soil is too dry, your plant will let you know by looking a bit down in the dumps. On the flip side, too much water can also cause drooping, as the roots might be suffocating. It's like when you eat too much at Thanksgiving dinner and just want to lie flat!

To fix this, ensure that your plant is in a pot with good drainage and water it when the top inch of soil feels dry. If you're unsure, it's safer to underwater than overwater. You can also lift the pot to check its weight—if it feels light, it might be time for a drink.

2. Brown Leaf Edges

Finding crispy brown edges on your calathea can be a heart-sinking moment. These plants love humidity, and dry air is often the culprit behind those unsightly edges. If your home resembles the Sahara Desert, your calathea might not be too thrilled.

Consider placing a humidifier nearby or misting the leaves regularly. Another option is to group it with other plants, creating a microclimate that boosts humidity naturally. Remember, a bathroom or kitchen can be a great spot for calatheas since these rooms tend to have higher humidity levels. Just be sure they get enough indirect light.

3. Yellowing Leaves

When leaves start to yellow, it can be a sign of several issues. Overwatering is a common reason, as it can lead to root rot. Make sure your pot has proper drainage and that you're not letting the plant sit in water.

Another potential cause could be underwatering. Check if the soil is bone dry and adjust your watering schedule accordingly. Lastly, consider the light levels. Too little light can also lead to yellowing leaves, so ensure your calathea is getting bright, indirect light.

4. Leaf Curling

Leaf curling in calatheas can be quite dramatic, almost like they're trying to roll up into a cocoon. This can happen due to low humidity, incorrect watering, or even temperature stress.

Check your watering routine and ensure the plant is not too hot or cold. Calatheas prefer temperatures between 65-80°F (18-27°C). Using a pebble tray filled with water beneath the plant can help increase humidity, which often resolves the curling.

5. Pests: Spider Mites and Aphids

Even the most careful plant parent can have an unwanted pest issue. Spider mites and aphids are common enemies of the calathea. They are tiny, but their damage can be significant.

To combat these pests, regularly inspect your plant. If you spot any intruders, you can wash them off with a gentle stream of water. For more severe infestations, neem oil or insecticidal soap can be effective. Remember to isolate the affected plant to prevent the pests from spreading to others.

6. Leaf Spot Diseases

If you notice spots on your calathea's leaves, it might be suffering from a fungal or bacterial disease. Leaf spots often occur due to high humidity and poor air circulation.

Ensure your plant is in a well-ventilated area and avoid getting the leaves wet when watering. If you see any affected leaves, prune them to prevent the disease from spreading. Fungicidal sprays can also help if the problem persists.

7. Fading Leaf Patterns

The beautiful patterns on calathea leaves are part of their charm, so it can be disappointing to see them fade. This is often a result of too much direct sunlight. Calatheas prefer indirect light, so find a spot where they get bright but filtered light.

If moving your plant isn't an option, consider using sheer curtains to diffuse the sunlight. This will help maintain those stunning leaf patterns that make calatheas so beloved.

8. Slow Growth

Calatheas are not the fastest growers, but if yours seems to be at a complete standstill, it might be signaling a problem. Check the light levels, as insufficient light can slow growth. Also, make sure your plant is getting enough nutrients. Consider using a balanced, water-soluble fertilizer during the growing season, but be cautious not to over-fertilize.

Temperature can also be a factor. If it's too cold, your calathea might be conserving energy rather than putting it into new growth. Make sure your plant is in a warm, draft-free location.

9. Root Rot

Root rot is a serious issue that can be fatal for your calathea if not addressed promptly. It usually results from overwatering or poor drainage.

If you suspect root rot, remove the plant from its pot and examine the roots. Healthy roots should be white and firm. If you find any mushy, brown roots, trim them away using sterilized scissors. Repot your plant in fresh soil and reduce watering frequency to prevent recurrence.

Final Thoughts

Round leaf calatheas can be a bit challenging, but with some attention to detail and a little patience, you can enjoy their vibrant beauty without too much trouble. From drooping leaves to pest invasions, understanding these common issues will help you keep your calathea thriving.
