Your -4°C to -7°C = severe freeze damage. Yellow leaves, black tips, fruit rot = cold injury.

Emergency Care

1. Build insulated shelter (straw bales + frost cloth + heat lamp if possible).
2. Prune all blackened wood to live tissue.
3. Fertilize now (citrus feed) to push recovery growth.
4. Reduce watering—cold + wet = root rot.

Mini mondo grass in pot competes for water; consider removing.
