About Geranium clarkei 'Kashmir White'

Geranium clarkei 'Kashmir White' · also called Kashmir White cranesbill, Clarke's cranesbill white · flowering

Geranium clarkei 'Kashmir White' is a vigorous, spreading hardy cranesbill with finely divided, deeply cut foliage. In summer it carries large, saucer-shaped white flowers delicately pencilled with lilac-pink veins. Easygoing and reliable on most soils including clay, it makes excellent weed-suppressing ground cover for sun or partial shade in borders and informal plantings.

Growth habit: Vigorous, rhizomatous, spreading perennial that forms broad weed-suppressing colonies; herbaceous, dying back in winter and reshooting strongly in spring.

Watch for — Vine weevil: Larvae feed on roots and rhizomes of potted plants, causing wilting. Check rootballs at repotting and use nematode controls if grubs are present.

What fertiliser geranium clarkei 'kashmir white' actually wants — and why

Geranium clarkei 'Kashmir White' flowers best on poor soil — feed it and you get a lush leafy plant with very few blooms, the exact opposite of what you want.

Little or nothing. Rich, especially nitrogen-rich, soil pushes foliage at the expense of flowers in this plant — lean ground is the technique, not a deficiency.

For the language behind the three numbers on the bottle — what nitrogen, phosphorus and potassium each do — see the NPK ratio explained entry. The short version for geranium clarkei 'kashmir white': match the feed to the job the plant is doing right now, not to a generic “plant food” on the shelf.

How often to feed geranium clarkei 'kashmir white', and which months

Feeding only earns its keep while the plant is in active growth and can use the nutrients — pour feed into a dormant or low-light plant and it simply builds up as root-burning salt. For geranium clarkei 'kashmir white':

Undemanding. A spring compost mulch or one light balanced feed is enough. Avoid high-nitrogen feeds, which encourage soft, floppy growth at the expense of flowers. In practice: no routine feeding at all for geranium clarkei 'kashmir white' — at most a thin compost mulch for soil structure, never a flowering or nitrogen feed.

The dormant-season rule matters more than the exact interval: skip feeding entirely when geranium clarkei 'kashmir white' is resting. For the wider context on indoor feeding rhythms across the seasons, the houseplant fertiliser schedule walks through the year month by month.

What strength to mix for geranium clarkei 'kashmir white'

None is the correct answer for geranium clarkei 'kashmir white'. The flower-versus-foliage trade-off is the whole point: hold back and you get the display.

Organic vs synthetic feeds for geranium clarkei 'kashmir white'

Organic options

A thin compost mulch for soil structure is the absolute most; mostly, give it nothing. UK/US: leave it lean — no manure, no liquid feed. Poor soil is the active ingredient here.

Synthetic / liquid feeds

None. Synthetic feeds, particularly anything with appreciable nitrogen, directly suppress flowering in geranium clarkei 'kashmir white'.

Brand names are examples, not endorsements, and UK and US ranges differ — check the label’s own NPK and dilution rate, since formulations change.
