Citrus Storm Damage: No Wound Dressing Needed

Wind tore a large limb off a citrus tree. Do not apply copper sulfate or any wound dressing. The tree will heal naturally. Next spring, watch for borer dust (frass) at wound; if seen, spray Merit (imidacloprid) to prevent infestation. No sealants, paints, or chemicals needed.

Natural Healing

Leave wound open.
Monitor for borers in spring.
Spray Merit only if borers appear.
