About Paeonia mlokosewitschii
Paeonia mlokosewitschii · also called Molly the witch peony, Caucasian peony · flowering
Affectionately called 'Molly the witch', this Caucasian species peony bears single, lemon-yellow cupped flowers in mid to late spring above soft glaucous blue-green foliage, followed by striking red-and-black seed pods. A choice, early-flowering, long-lived clump-former, it is fully hardy and prefers full sun to light shade in deep, fertile, well-drained alkaline soil.
Growth habit: Clump-forming herbaceous species peony; emerges early in spring with rounded glaucous foliage, flowers in mid to late spring, then dies back in late summer. Generally self-supporting with its single flowers.
What fertiliser paeonia mlokosewitschii actually wants — and why
Paeonia mlokosewitschii 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 paeonia mlokosewitschii: 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 paeonia mlokosewitschii, 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 paeonia mlokosewitschii:
Feed in early spring with bonemeal or a low-nitrogen, phosphorus- and potassium-rich fertiliser, and mulch with compost in autumn. Avoid high-nitrogen feeds that favour leaf over flower and soften stems. 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 paeonia mlokosewitschii 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 paeonia mlokosewitschii
Half strength is the safe default for paeonia mlokosewitschii — 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 paeonia mlokosewitschii first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the paeonia mlokosewitschii watering schedule.
Signs you are over-feeding paeonia mlokosewitschii
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for paeonia mlokosewitschii:
- 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 paeonia mlokosewitschii
- 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 paeonia mlokosewitschii care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Flush the pot of paeonia mlokosewitschii 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 paeonia mlokosewitschii
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.

What does over-feeding paeonia mlokosewitschii look like?
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. Feeding paeonia mlokosewitschii year-round on a fixed schedule, including dark winter months, is the most common mistake — it cannot use the nutrients in low light and the surplus simply burns the roots and crusts the soil.
Should I flush the soil of paeonia mlokosewitschii?
Flush the pot of paeonia mlokosewitschii 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.
