CULTURE: In Canada, citrons are best started indoors 3-4 weeks before last frost. Start 3-4 seeds in a 3-4" pot. Transplant to the recommended plant spacing, do not break clumps apart.
SOIL: Citrons like well drained, sandy-silty loam, high in organic matter pH 6.0- 6.8
FERTILITY: Enrich with compost or well rotted manure in spring. Citrons are heavy users of nitrogen, potassium and calcium. GERMINATION: For proper germination soil must be at least 72F/22C for 5 days. Cooler soil temperature will result in poor germination.
SPACING: Plant in clumps 3-4 seeds per clump, 24" apart in rows 4-7ft apart.
