Monstera plants are popular houseplants known for their striking foliage and easy care. Proper fertilization is essential for healthy growth, but many plant owners make mistakes that can harm their Monstera. Here are the top 10 fertilizing mistakes to avoid to keep your Monstera thriving.
1. Over-fertilizing Your Monstera
Applying too much fertilizer can lead to salt buildup in the soil, causing root burn and stunted growth. Always follow the recommended dosage and frequency for your specific fertilizer type.
2. Using the Wrong Type of Fertilizer
Not all fertilizers are suitable for Monsteras. Use a balanced, water-soluble fertilizer with an NPK ratio like 20-20-20 or a formula specifically designed for houseplants.
3. Fertilizing at the Wrong Time
Fertilize during the active growing season, typically spring and summer. Avoid fertilizing in winter when the plant’s growth naturally slows down.
4. Fertilizing When the Soil Is Dry
Applying fertilizer to dry soil can cause root damage. Always water your Monstera thoroughly before fertilizing to ensure proper absorption.
5. Ignoring Signs of Over-fertilization
Look out for yellowing leaves, brown tips, or a white crust on the soil surface. These are signs of over-fertilization and require flushing the soil with water.
6. Not Diluting Fertilizer Properly
Using concentrated fertilizer without dilution can harm your plant. Always dilute according to the package instructions to prevent root damage.
7. Fertilizing Too Frequently
Fertilizer is not needed every week. Typically, once a month during the growing season is sufficient. Over-fertilizing can lead to nutrient imbalances.
8. Forgetting to Adjust Fertilizer for Size
Young or small Monsteras require less fertilizer than mature plants. Adjust your fertilizing schedule accordingly to avoid excess nutrients.
9. Using Old or Expired Fertilizer
Expired fertilizers can lose potency or develop harmful compounds. Always check expiration dates and store fertilizers properly.
10. Neglecting to Clean Fertilizer Spills
Spills of fertilizer on leaves or soil can cause burn spots or attract pests. Clean up any spills promptly to protect your Monstera.
