Citrus Tree Care for Northeast Florida

Citrus care for Northeast Florida including planting, watering, nutrition, cold protection, citrus greening, pests, and responsible treatment guidance.

Healthy citrus starts with certified nursery stock, full sun, excellent drainage, correct irrigation, nutrition, and realistic management of citrus greening and other pests.

Planting, Watering & Nutrition

Plant source: Purchase healthy, certified citrus nursery stock produced under Florida citrus propagation rules.
Sun: Plant in full sun in a warm location with good air movement.
Drainage: Do not plant in a low area that remains wet after summer rain.
Planting: Set the root ball at or slightly above surrounding grade; do not bury the trunk or graft union.
Watering: Water newly planted trees regularly while establishing, then irrigate deeply during dry periods without keeping the root zone constantly saturated.
Mulch: Mulch can conserve soil moisture, but keep mulch several inches away from the trunk.
Nutrition: Use a citrus fertilizer program appropriate to tree age and local conditions. Split applications are generally safer than large doses.
Micronutrients: Yellowing can have many causes. Diagnose iron, magnesium, manganese, zinc, root, irrigation, or greening problems before treating blindly.

Citrus Greening (HLB) & Psyllids

Reality: Huanglongbing (HLB/citrus greening) is widespread in Florida and has no simple homeowner cure.
Symptoms: Possible signs include blotchy asymmetrical leaf mottling, small or lopsided bitter fruit, premature fruit drop, twig dieback, and gradual decline.
Vector: Asian citrus psyllids spread the bacterium that causes HLB.
Management: Support tree health with correct irrigation and nutrition, reduce avoidable stress, and follow current recommendations for psyllid management.
Treatment claims: Do not describe insecticides or nutritional products as a cure for HLB.
Diagnosis: When symptoms are uncertain, contact university extension research or a qualified citrus professional.

Common Pest & Disease Management

Inspect: Look at new growth, undersides of leaves, stems, fruit, and soil conditions before choosing a treatment.
Aphids/scale/whiteflies: Natural enemies, horticultural oils, or insecticidal soaps may help when properly timed and labeled for citrus.
Leafminer: Damage is most visible on tender flush. Mature trees often tolerate cosmetic injury better than young trees.
Fruit flies: Sanitation and prompt harvest are important; remove fallen and overripe fruit.
Fungal disease: Good airflow, sanitation, and avoiding unnecessary leaf wetness can reduce some disease pressure.
Pesticides: Use only products currently labeled for citrus and the target pest. The pesticide label—not a website—is the legal direction for rate, interval, harvest restrictions, and application method.

Cold Protection & Recovery

Before cold: Choose a protected site, keep the soil appropriately moist, and cover young trees with frost cloth secured to the ground when freezes are forecast.
Graft: Protect the graft union and lower trunk of young grafted trees.
Containers: Move container citrus into a sheltered location when practical.
After cold: Do not rush to prune immediately after freeze injury; wait until new growth shows the extent of living wood.
Rootstock: If growth emerges from below the graft, remove it; rootstock shoots will not produce the desired cultivar.
