What are you growing in the GH borders?
I first used the MF when I planted new standard roses in a border, one had had a rose in before. So I planted in with the MF and fed the roses every year since with rose feed and some grow more on the rest of the border. I would say that they have responded well to the feed?
I haven't used MF again on those borders u til last autumn when I added in more roses.
It's expensive stuff so I have just used it when
I've planted in roses, shrubs or trees.
