Either starving geranium wallichianum 'buxton's variety' in a thin mix or drowning it in a heavy, badly drained one. It wants the rich-but-free-draining middle, plus a flowering (higher-potassium) feed in season.

pH — does it matter for geranium wallichianum 'buxton's variety'?

Most flowering plants, including geranium wallichianum 'buxton's variety', 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 wallichianum 'buxton's variety' in pots if you add grit and a flowering feed. In beds, improving the existing soil with compost and ensuring drainage beats any bag.

Drainage and the pot

For perennials, refresh the top layer and feed each spring rather than disturbing the roots; for container displays, start with fresh rich mix each season. When the time comes, our repotting guide for geranium wallichianum 'buxton's variety' covers the timing and technique step by step.
