pH — does it matter for geranium sanguineum 'album'?

Most flowering plants, including geranium sanguineum 'album', do well around pH 6.0-7.0. A cheap soil test is worth it outdoors; one notable exception is any acid-lover (such as some hydrangeas), where pH directly changes flower colour.

DIY mix vs a bagged one

A quality bagged compost works for geranium sanguineum 'album' in pots if you add grit and a flowering feed. In beds, improving the existing soil with compost and ensuring drainage beats any bag.
