The Philodendron is one of the most popular houseplants, known for its impressive leaves and easy care. But even this robust plant can occasionally suffer from diseases or other problems. Philodendron care mistakes are often the cause. In this article, you will learn how to recognize the most common problems, fix them, and get your Philodendron back into top shape.
Common Problems with Philodendrons
1. Yellow leaves
Causes:
- Overwatering: Too much water leads to waterlogging and root rot.
- Nutrient deficiency: A lack of nitrogen in particular is indicated by yellow leaves.
Solutions:
- Only water when the top layer of soil is dry and use a pot with drainage holes.
- Fertilizing: Use a liquid fertilizer for green plants every two weeks during the growing season.
2. Brown leaf tips
Causes:
- Air that is too dry: Philodendrons love high humidity.
- Salt deposits: Too many fertilizer salts can damage the roots.
Solutions:
- Place a bowl of water or a humidifier near the plant.
- Occasionally rinse the soil with clean water to wash out excess salts.
3. Leaves curl
Causes:
- Lack of water: Too little water can cause stress.
- Drafts: Cold air currents are harmful.
Solutions:
- Water regularly without causing waterlogging.
- Place the Philodendron in a location protected from drafts.
4. Soft or mushy stems
Cause:
- Root rot due to waterlogging or overwatering.
Solutions:
- Remove the plant from the soil and cut off any rotten roots.
- Replant the Philodendron in fresh, well-drained soil.
5. Spots on the leaves
Causes:
- Fungal infections caused by high humidity and poor air circulation.
- Bacterial diseases that are often caused by too much water.
Solutions:
- Remove infected leaves and ensure better air circulation.
- Reduce humidity and avoid allowing water to stand on the leaves.
Pests and how to get rid of them
1. Spider mites
- Signs: Fine cobwebs and dry, spotty leaves.
- Control: Spray the plant with water or use neem oil.
2. Thrips
- Signs: Silvery shimmering spots on the leaves.
- Control: Yellow boards and a biological insecticide help effectively.
3. Scale insects
- Signs: Small, hard, brown bumps on stems and leaves.
- Treatment: Remove the lice with a cotton swab soaked in alcohol.
Avoid Philodendron Care Mistakes
- Location: Philodendrons prefer bright, indirect light. Too little light leads to sparse growth, too much sun burns the leaves.
- Watering: Water sparingly and only when the top layer of soil is dry. Waterlogging is the most common cause of root rot.
- Fertilizing: Fertilize regularly during the growing season (spring and summer), but don't overdo it - over-fertilizing can damage the roots.
- Humidity: Maintain a humidity level of 50 to 70%, especially in winter when heating dries out the air.
Tips for a healthy Philodendron
- Regular inspection: Check your plant regularly for signs of disease or pests.
- Repotting: Philodendrons should be repotted into fresh soil every 1-2 years to avoid nutrient deficiencies.
- Cleaning: Wipe the leaves to remove dust and improve photosynthesis.
- Prevention: Isolate new plants for a few weeks to avoid spreading pests or diseases to existing plants.
