Watering Techniques
Watering is essential for Jerusalem artichokes, particularly during dry periods. Consistent moisture is vital for root development and tuber production. Overwatering, however, can lead to root rot and other fungal diseases. The ideal approach is to water deeply but less frequently, allowing the soil to dry slightly between waterings. Observe the soil moisture regularly; water when the top inch or two feels dry to the touch.
The frequency and amount of water needed will depend on the local climate, soil type, and stage of plant growth. For example, during periods of intense heat, you might need to water more frequently than in cooler, wetter weather.
Fertilization Practices
Jerusalem artichokes are relatively resilient and don’t require heavy fertilization. However, a balanced application of fertilizer can enhance growth and tuber development. A balanced granular fertilizer, such as one with an NPK ratio of 10-10-10, can be applied in the spring, after the last frost. Alternatively, compost or well-rotted manure can be incorporated into the soil as a natural, organic fertilizer.
Spread the fertilizer evenly around the plants, avoiding contact with the stems or leaves. Applying fertilizer too close to the plants can lead to leaf burn. It’s essential to follow the manufacturer’s instructions for proper application rates and timing.
Growing Jerusalem artichokes requires well-drained soil and plenty of sun.
