About Heuchera 'Plum Pudding'
Heuchera 'Plum Pudding' · also called Coral Bells 'Plum Pudding', Alumroot 'Plum Pudding' · flowering
Heuchera 'Plum Pudding' is a classic perennial with deep, metallic plum-purple foliage featuring a distinctive silver overlay. Slender stems bear small pale-pink flowers in late spring and early summer. Hardy and drought-tolerant once established; excellent as ground cover or a container accent in partial shade.
Growth habit: Low, mounding semi-evergreen perennial with metallic foliage
Watch for — Leaf burn: Crispy leaf edges in hot, dry, sunny conditions; provide afternoon shade and mulch.
What fertiliser heuchera 'plum pudding' actually wants — and why
Heuchera 'Plum Pudding' 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 heuchera 'plum pudding': 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 heuchera 'plum pudding', 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 heuchera 'plum pudding':
One application of slow-release balanced fertiliser in early spring is usually sufficient for established plants in good soil. In containers, apply a dilute balanced liquid feed monthly from April to August to compensate for nutrient leaching. Treat that as monthly 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 heuchera 'plum pudding' 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 heuchera 'plum pudding'
Half strength is the safe default for heuchera 'plum pudding' — 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 heuchera 'plum pudding' first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the heuchera 'plum pudding' watering schedule.
Signs you are over-feeding heuchera 'plum pudding'
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for heuchera 'plum pudding':
- 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 heuchera 'plum pudding'
- 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 heuchera 'plum pudding' care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Flush the pot of heuchera 'plum pudding' 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 heuchera 'plum pudding'
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.

Lower leaves yellow and drop while the soil is correctly watered. Feeding heuchera 'plum pudding' 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 heuchera 'plum pudding'?
Flush the pot of heuchera 'plum pudding' 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.
