A cold period of at least 10 weeks below 4°C is required for plants to produce seed. May cross-pollinate with other Beta vulgaris plants including some varieties of beetroot, silverbeet and mangel wurzel. Pollen is very fine, making isolation cages and paper bagging ineffective; only flowering plants need to be isolated from each other.
