Eggshell powder topdress：Crush dried eggshells into fine powder; sprinkle lightly around the base of young trees; avoid direct contact with the trunk to prevent rotPruning
- Remove dead or damaged branches in late winter to maintain tree structure and airflow
- Thin overcrowded lower branches to improve light penetration to the base of the tree
- Avoid heavy pruning, as conifers do not regrow foliage from old wood
