About Anne Thomson Cranesbill
Geranium 'Anne Thomson' · also called Anne Thomson Cranesbill, Anne Thomson Geranium · flowering
Geranium 'Anne Thomson' is a hybrid of G. procurrens and G. psilostemon bred by Alan Bremner of Orkney, closely related to 'Ann Folkard' but selected for improved heat tolerance and a more compact, less-sprawling habit. The bright chartreuse young leaves mature to mid-green, and large magenta-pink flowers with a black eye and dark veins are produced abundantly all summer. The RHS awarded it AGM status in 2005. The most important care fact is to site it in sun with well-drained soil and allow space for the trailing stems. ASPCA's 'Geranium' toxic listing refers to Pelargonium; true cranesbills are not confirmed non-toxic by ASPCA, so treat with caution around pets.
Ideal humidity: Low to moderate
Watch for — Vine weevil: White grubs in the root zone cause sudden wilting; adult notching on leaf margins is the first sign — treat with Steinernema kraussei nematodes applied to moist soil in late summer.
The watering schedule, season by season
Anne Thomson Cranesbill flowers best on steady, even moisture — let it dry out hard and it drops buds; keep it soggy and the roots rot before it can bloom. The base rhythm for anne thomson cranesbill is moderate; water during dry spells, but the real interval moves with the season, the light and the pot — so treat the figures below as a starting point and always confirm with the plant itself.
- Spring & summer (active growth): Spring and summer (active growth and bloom): keep evenly moist, watering when the top 2-3 cm is dry — typically when the soil tells you it is time.
- Autumn (slowing down): Autumn: ease back as flowering finishes and growth slows; let it dry a little more between waterings.
- Winter (rest / dormancy): Winter / rest: water sparingly while it rests, then resume as new growth and buds appear.
Keep soil reasonably moist but well-drained during the growing season; the plant's superior heat tolerance means it can sustain flowering through summer with regular watering.

How to tell anne thomson cranesbill needs water
A calendar is the worst way to water anne thomson cranesbill. Check the plant and the soil instead — for this species, look for these signals in order:
- The top 2-3 cm of soil is dry to the touch.
- Leaves or flower stems lose turgor and start to droop.
- Buds stall or the pot feels light.
The most reliable single check is the first one on that list. When two signals agree, water; when they disagree, wait a day and look again — under-watering anne thomson cranesbill for a day is almost always safer than over-watering it.
Overwatering vs underwatering anne thomson cranesbill
The two failure modes can look alike at a glance, so check the soil weight and wetness before you decide. For anne thomson cranesbill specifically:
Signs you are overwatering
- Yellowing leaves, bud drop, and a heavy, constantly wet pot.
- Mushy stems or crown rot at soil level.
- Fungus gnats and a sour soil smell.
Signs you are underwatering
- Wilting, bud and flower drop, and crispy leaf edges.
- A faded, stressed look and a rootball that has pulled from the pot sides.
Erratic watering — bone dry then flooded — makes anne thomson cranesbill drop its buds and flowers. Consistency through the budding period is what protects the display.
Water quality notes
Tap water is generally fine for anne thomson cranesbill unless your water is very hard; rainwater is a safe default if leaf tips brown.
Seasonal and environmental adjusters
Every figure above shifts with the conditions in your home. For anne thomson cranesbill, the levers that matter most are:
- A blooming plant in good light drinks faster than a resting one — shorten the interval during flowering.
- Brighter, warmer spots dry the pot faster; check before watering rather than fixing a date.
- Empty the saucer after every water so the roots are never sitting in run-off.
Pot choice is part of this too — work out the right size with the pot size calculator, since a pot that is too big stays wet long enough to rot the roots of anne thomson cranesbill.
