High-Nitrogen Compost for Houseplants: Dilute with Potting Soil, Adjust Fertilizer

Can't Remove Nitrogen, Must Dilute

Mix nitrogen-rich compost (crow manure under plane tree) with purchased potting soil to reduce strength.

Plant-Specific Effects

• Foliage plants: Tolerate high nitrogen—grow larger, bushier. Avoid if too fresh (burns roots).
• Blooming plants: High nitrogen suppresses flowers. Use low-nitrogen, high-phosphorus/potash fertilizer (e.g., 5-20-20).
