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...
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
