The Basics
When to plant: Citrus can be planted almost any time of year. The best time is after the last frost in spring (mid-March)
Harvest window: Year-round, depending on variety
Fertilization: Nitrogen in January, again in May/June timeframe. Monitor for zinc, iron, and other micronutrient deficiencies and correct through foliar application or soil pH adjustments.
Annual care overview:
- Most citrus requires frost protection when temperatures dip below 25 degrees Fahrenheit; monitor and protect citrus plants (cover, lights, a south-facing wall are examples)
- Monitor for whiteflies, scale, mites, and sooty mold; many of which can be controlled by controlling for ants.
