Petchoa Irrigation

x Petchoa J. M. H. Shaw

Petchoa irrigation requires monitoring of drainage and substrate pH to prevent root rot and chlorosis. The irrigation regimen is based on alternating 'wet-dry' cycles while maintaining a medium acidity in the 5.5–6.0 range.

In the reference 6 varieties crop Petchoa, where this is mentioned in the description.

As an intergeneric hybrid, Petchoa is highly sensitive to waterlogging and standing water. To prevent root rot, it is necessary to use a loose, aerated substrate and perform irrigation by alternating drying and wetting cycles. Frequent moisture is required in the first weeks after transplanting; after rooting, irrigation intensity should be reduced, based on soil condition.

A critical factor is the control of substrate pH, which must be 5.5–6.0. If the pH rises above 6.2, iron uptake is impaired, leading to the development of chlorosis; therefore, acidification is required when using hard water. Basal irrigation is preferred, as moisture on the foliage under poor ventilation conditions triggers fungal diseases. Despite these requirements, due to its well-developed root system, the hybrid possesses increased resistance to short-term drought compared to its parental forms.
