About Philippe Vapelle Cranesbill

Geranium 'Philippe Vapelle' · also called Philippe Vapelle Cranesbill, Philippe Vapelle Geranium · flowering

Geranium 'Philippe Vapelle' is a hybrid of G. renardii and G. platypetalum raised by Alan Bremner at Axletree Nursery in Scotland, forming a neat clump of attractive blue-grey, softly hairy, finely wrinkled lobed leaves. Blue-violet flowers with strongly dark-veined petals open in summer above the textured foliage. The single most important care fact is to provide a sunny, well-drained position — the renardii parent demands good drainage and dislikes poorly drained winter soils. The ASPCA 'Geranium' toxic listing refers to Pelargonium, not true cranesbills; true Geranium is not individually confirmed non-toxic, so treat with caution around pets.

Growth habit: Clump-forming, compact deciduous perennial with upright flowering stems above a basal mound of distinctively textured foliage.

Watch for — Vine weevil: Notched leaf margins indicate adult feeding; creamy-white grubs in the root zone cause sudden wilting; apply Steinernema kraussei nematodes to moist soil in late summer to early autumn.

What fertiliser philippe vapelle cranesbill actually wants — and why

Philippe Vapelle Cranesbill 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 philippe vapelle cranesbill: 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 philippe vapelle cranesbill, 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 philippe vapelle cranesbill:

Apply a balanced slow-release fertiliser in spring; excessive nitrogen encourages lush foliage at the expense of flowers. In practice: no routine feeding at all for philippe vapelle cranesbill — 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 philippe vapelle cranesbill 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 philippe vapelle cranesbill

None is the correct answer for philippe vapelle cranesbill. The flower-versus-foliage trade-off is the whole point: hold back and you get the display.

If the symptoms point at watering, light or roots rather than nutrition, the full philippe vapelle cranesbill care brief covers soil, humidity and the common problems for this species.

Flushing and leaching the salts

Organic vs synthetic feeds for philippe vapelle cranesbill

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 philippe vapelle cranesbill.

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