About Ann Folkard Cranesbill
Geranium 'Ann Folkard' · also called Ann Folkard Cranesbill, Ann Folkard Geranium · flowering
Geranium 'Ann Folkard' is a hybrid of G. procurrens and G. psilostemon raised by Reverend O. G. Folkard, notable for its strikingly bright chartreuse-yellow young foliage that darkens to mid-green, and its exceptionally long season of large magenta-pink flowers with distinctive black veins and a black eye. The scrambling, trailing stems twine through neighbouring plants in a mixed border and spread up to 90–120 cm. The most important care fact is to give it enough space to scramble without smothering smaller neighbours. ASPCA's 'Geranium' toxic listing refers to Pelargonium; true cranesbills are not confirmed non-toxic by ASPCA, so treat with caution around pets.
Growth habit: Sprawling, scrambling deciduous perennial forming a wide trailing mound with stems that weave through neighbouring plants.
What fertiliser ann folkard cranesbill actually wants — and why
Ann Folkard Cranesbill is an easy, light foliage feeder — a half-strength balanced liquid feed through the growing months keeps it green without forcing weak, sappy growth.
A balanced general houseplant feed (roughly even N-P-K) is exactly right — it is grown for foliage, so steady, moderate nitrogen for healthy leaves is the goal, not a bloom or root formula.
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 ann folkard 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 ann folkard 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 ann folkard cranesbill:
Apply a balanced fertiliser in spring; a single mulch of well-rotted compost in early spring provides both nutrients and moisture retention. Treat that as sparingly through the growing season between spring through early autumn (roughly March to September); ease off in autumn and stop entirely in the low light of winter.
The dormant-season rule matters more than the exact interval: skip feeding entirely when ann folkard 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 ann folkard cranesbill
Half strength is the safe default for ann folkard cranesbill — houseplant feeds are formulated strong, and the diluted dose is gentler on the roots while still ample for foliage.
Feeding always goes onto already-damp soil, never dry roots — water ann folkard cranesbill first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the ann folkard cranesbill watering schedule.
Signs you are over-feeding ann folkard cranesbill
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for ann folkard cranesbill:
- Brown, crispy leaf tips and edges with no sign of underwatering.
- A white, crusty salt deposit on the soil surface or pot rim.
- Weak, pale, stretched new growth that flops.
- Lower leaves yellow and drop while the soil is correctly watered.
Signs you are under-feeding ann folkard cranesbill
- Uniformly pale or yellow-green leaves, oldest first.
- Noticeably small new leaves and stalled growth in good light and season.
- A generally tired, lacklustre look despite correct watering and light.
If the symptoms point at watering, light or roots rather than nutrition, the full ann folkard cranesbill care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Flush the pot of ann folkard cranesbill with plain water until it runs freely from the base every couple of months in the feeding season — it washes out the fertiliser salts that cause brown tips.
Organic vs synthetic feeds for ann folkard cranesbill
Organic options
A diluted seaweed or worm-casting feed, or fish emulsion if you can tolerate the smell indoors. UK: Westland or Baby Bio Organic, dilute seaweed; US: Espoma Indoor! or Neptune's Harvest fish & seaweed. Slow, gentle and hard to overdo.
Synthetic / liquid feeds
A general-purpose houseplant liquid at half strength — UK: Baby Bio, Westland Houseplant Feed or Phostrogen; US: Miracle-Gro Indoor Plant Food or Schultz. Convenient and fast-acting; the only risk is overdoing it.
Brand names are examples, not endorsements, and UK and US ranges differ — check the label’s own NPK and dilution rate, since formulations change.
