When to switch to a high potash feed?

Hi guys,

I have some plants in containers such as hardy geraniums and pelargoniums and I am a little confused about what to feed them and when.

Obviously when the plant starts growing in spring it produces it's fresh green leaves first and then it starts to produce it's flowers... So do I feed with a high nitrogen feed at first and then a high potash feed (tomato food) when it starts to produce flower buds? Or do I just feed with tomato food from the very beginning?

Thanks
Craigh

    Balanced fertiliser like BFB, early in the season, followed by high potash feed to help produce flowers.

    Geraniums, true or not, are such s*s of a b* that fostering their greens is a waste of time, at least to me. Feed them for flowers from the start and you'll get better results.

    Punkdoc do you feed BFB to plants in containers?

    I also have a new Gaura In a container too after my other one died and also a Nepeta.

    So again would I use FBB on these too or stick with a liquid tomato food all their life?

    For permanent plantings, yes.
    For bedding, no.
