🌱 How to Care for Black-eyed pea to Prevent Anthracnose?

💧 How to Water

Water every 7 days, letting the soil dry out completely between waterings. Black-eyed peas are highly drought-tolerant — overwatering causes root rot. Reduce frequency after establishment.

☀️ Lighting

Requires full sun — at least 6-8 hours of direct sunlight per day. This is a tropical plant that does not adapt well to shade; insufficient light leads to fewer pods and increased susceptibility to fungal diseases.

🪴 Ideal Soil

Prefers well-draining sandy loam with pH 5.5–6.5. Avoid waterlogged or heavy clay soils. Tolerates nitrogen-poor soils thanks to biological nitrogen fixation by rhizobium bacteria in root nodules.
