📝 Growing Notes
Orange trees thrive with marigold companions that deter nematodes and a white clover ground cover that fixes nitrogen. Basil planted nearby repels soft-bodied insects including aphids, spider mites, and whiteflies. Citrus greening disease (HLB), carried by the Asian citrus psyllid, is the most serious contemporary pest threat.
