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.

Mature size: Approximately 40 cm tall and 40 cm wide.

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.

How to tell philippe vapelle cranesbill needs repotting

Repotting on a calendar is less reliable than reading the plant. For philippe vapelle cranesbill, watch for these signs:

Roots spiralling thickly out of the drainage holes or pushing the whole plant up out of the pot.
The pot is so packed that water runs straight through in seconds and barely wets the soil.
It has split a plastic pot, or the rootball is a solid mass with almost no soil left when you slide it out.
Growth and (for philippe vapelle cranesbill) flowering have clearly stalled despite good light and feeding — but remember this plant likes being snug, so a little crowding alone is not a reason to repot.

For the underlying biology of a pot-bound root system and why it stalls a plant, see our guide to spotting and fixing a root-bound plant.

How often to repot philippe vapelle cranesbill

Only every 2–4 years, when genuinely crowded. Philippe Vapelle Cranesbill is one of the plants that genuinely prefers a snug pot — it grows and flowers better with its roots a little restricted, so resist the urge to repot it on schedule. Clump-forming, compact deciduous perennial with upright flowering stems above a basal mound of distinctively textured foliage..

What size pot to step philippe vapelle cranesbill up to

Go up only one pot size — roughly 2–3 cm (about an inch) wider in diameter, no more. Philippe Vapelle Cranesbill positively prefers a snug pot: it flowers and grows better when the roots are a little restricted. The single biggest repotting mistake here is over-potting — dropping philippe vapelle cranesbill into a pot two or three sizes up. All that surplus soil holds water the small root system cannot use, stays cold and wet, and rots the roots within weeks. When in doubt, choose the smaller pot.

The best time of year to repot philippe vapelle cranesbill

Early spring, just as new growth restarts, is the ideal window for philippe vapelle cranesbill. The plant is moving into its strongest growth phase and re-roots into fresh soil quickly. Avoid repotting in winter dormancy or, for flowering plants, while it is in bud or bloom — recovery is slowest then and you risk dropping the flowers.

Step-by-step: repotting philippe vapelle cranesbill

Confirm it actually needs it. Slide philippe vapelle cranesbill out and check the roots. Only continue if it is genuinely packed — this plant prefers a snug pot, so if there is still soil and room, put it straight back.
Pick a pot only one size up. Choose a pot just 2–3 cm wider with good drainage. Resist anything bigger; over-potting is the main killer here.
Ease it out gently. Water lightly the day before, then tip philippe vapelle cranesbill out, supporting the base. Tease the outer roots free only enough to stop them circling.
Repot at the same depth. Add a layer of fresh moderately fertile, well-drained, set the plant so the soil line sits exactly where it did before, and backfill around the sides, firming lightly.
Settle it in. Water once to settle the soil, then let it sit. Hold off on more water until the top of the soil dries — fresh soil around a small root system stays wet for a while.

Aftercare

Because the new soil holds more water than the old crammed rootball did, ease right back on watering — let the top of the soil dry before you water philippe vapelle cranesbill again, or you will rot the roots in the very pot you just moved it to. Keep it out of harsh direct sun for a fortnight. Do not fertilise for about 4 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for philippe vapelle cranesbill

Philippe Vapelle Cranesbill wants moderately fertile, well-drained. Prefers a well-drained to sandy, moderately fertile soil; inherits the G. renardii preference for dryish conditions and will not thrive in waterlogged sites. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting philippe vapelle cranesbill — frequently asked questions

How often should you repot philippe vapelle cranesbill?

Only every 2–4 years, when genuinely crowded for philippe vapelle cranesbill. Only repot philippe vapelle cranesbill every 2–4 years, and only when it is genuinely root-bound — it flowers and grows best slightly crowded. Step up just one pot size in spring using moderately fertile, well-drained. The key mistake is over-potting: a too-big pot stays wet and rots the roots.

What size pot does philippe vapelle cranesbill need?

When is the best time of year to repot philippe vapelle cranesbill?

Does philippe vapelle cranesbill like to be root-bound?

Yes — philippe vapelle cranesbill genuinely flowers and grows best when slightly pot-bound, so do not rush to repot it. The mistake to avoid is over-potting into a much larger pot: the excess soil stays wet, the roots cannot use it, and the plant rots. Only repot every few years and only one snug size up.

Should you fertilise philippe vapelle cranesbill after repotting?

Not immediately. Wait about 4 weeks after repotting philippe vapelle cranesbill. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
