A response to the idiots who disliked: Video - a peach in September, the result of three pruning rules. Opened peach blossoms die at -5°C (23°F). The ovaries are most sensitive. Thanks to the long flowering period, when some flowers are in bloom and others are in bud, the trees produce a harvest, since the flowers in bud are not damaged by frost. I.M. Shaitan.
