Eggshell powder topdress：Sprinkle finely crushed, dried eggshells on soil surface at planting; mix lightly into top 2 cm of soil to add calcium without burning tender rootsPruning
- Thin seedlings to 5–7 cm apart when 2–3 true leaves emerge to allow sufficient space for root expansion
- Remove yellowing lower leaves to improve airflow and reduce pest and disease risk
- Pinch off emerging flowering stems if bolting occurs to redirect energy to root development
