    Cross pollination ?

    I have some brassicas that have bolted and started flowering. They are growing in the same bed/close to each other. These brassicas are Napa cabbage "Granat" , Pak Choi "Canton Chinese" and Pak Choi "Thai white" Will they cross pollinate or are they likely to pollinate themselves immediately...

    Yellow leaf margins

    I have a couple Chinese cabbage plants. Today I noticed that one plant had a couple leaves near its centre with slightly yellow leaf margins. Is this a nitrogen deficiency or something else ? The plants are only starting to develop hearts now, 8 weeks old
