Editing Ribes nidigrolaria (section)

== Flowering, fruiting, and harvest ==

Colorado State University Extension recommends growing black and red jostaberries together where the goal is best fruit set. This is an extension recommendation, not a universal pollination guarantee for every planting. <sup>[[#cite_note-3|[3]]]</sup> In the breeding work, selfings were described as having low fertility, while fertile F2 hybrids were obtained in later generations; those results are breeding-program observations and should not be converted into a fixed home-orchard pollination rule. <sup>[[#cite_note-5|[5]]]</sup>

The breeding literature describes variation among genotypes in fruit characteristics and ripening, and later selection work targeted resistance, yield, fruit quality, and suitability for mechanical harvesting. <sup>[[#cite_note-5|[5]]]</sup><sup>[[#cite_note-6|[6]]]</sup> For garden harvest, pick when the berries are fully colored and soft. The crop can be labor-intensive to harvest, and bird protection may be needed. <sup>[[#cite_note-2|[2]]]</sup><sup>[[#cite_note-3|[3]]]</sup>
