Eggshells Aren't Good for All Plants: These Types Can React Poorly
Eggshells are often highlighted as a simple, natural, and completely free fertilizer for plants, which can easily be used in every household as an ecological alternative to commercial preparations.
TL;DR
- Eggshells are a free, natural fertilizer rich in calcium, beneficial for some plants like orchids.
- Adding eggshells can improve soil structure and promote healthy growth in suitable plants.
- Plants like azaleas, rhododendrons, hydrangeas, ferns, and gardenias can be negatively affected by eggshells.
- Eggshells can harm plants that prefer acidic soil by making it more alkaline.
- The color of hydrangeas can change, and plants may experience poor growth or yellowing leaves due to eggshell application.
- For best results, eggshells should be cleaned, dried, ground into powder, and used moderately only for appropriate plants.
