Last week I was unable to explain the advantage of removing potato
flowers. Bob Flowerdew mentioned it again on GQT yesterday.
I see the reasoning now. It is to stop the plants putting the energy
into making seeds, in the same way that if you let sweet peas (for
instance) go to seed, you will not get as many flowers.
Removing the flowers lets the plants put all their energy into making
potatoes.
I shall continue to do it!
