Frequently Asked Questions

Yellow Marconi (Capsicum annuum): What pest or disease should I watch for, and how do I stop it?

In Capsicum annuum, aphids and whiteflies often show up on young growth and can lead to sticky residue and virus risk; check the undersides of leaves weekly. Spray with insecticidal soap (or a strong water blast for light infestations) and repeat every 5–7 days until activity stops. If you see leaf wilt or dark, water-soaked spots, remove affected leaves and improve airflow around plants to reduce foliar fungal spread.

How often should I water Yellow Marconi during its main growth phase?

During active flowering and fruit set (roughly after plants are established and growing fast), keep soil evenly moist but not waterlogged—about 1 inch (2.5 cm) per week total, adjusted for heat and container size. Water deeply when the top 1 inch of soil feels dry to the touch, because inconsistent moisture can cause blossom drop and misshapen fruit.

How can I tell when Yellow Marconi is ready to harvest?

Harvest when the peppers reach their full mature size and the pods turn from pale green to a uniform bright yellow (usually around 80 days from transplant). For best flavor, pick when the skin is glossy and firm—if they soften or wrinkle, they are past peak. Use scissors or snips to cut the stem to avoid tearing the plant.
