About Indian Mallow
Abutilon indicum · also called Indian Mallow, Country Mallow · herb
Abutilon indicum is a soft-wooded perennial shrub native to tropical and subtropical Asia, widely used in Ayurvedic and traditional medicine across India, Southeast Asia, and Africa for its anti-inflammatory, analgesic, and emollient properties. In the garden it produces cheerful small yellow flowers and soft, heart-shaped, velvet-textured leaves on a bushy framework. The most important care fact is that this plant demands a warm, frost-free position — it will not survive temperatures below about 5°C. Abutilon is not listed on the ASPCA toxic plant database and is considered non-toxic to cats and dogs.
Growth habit: Bushy, upright, soft-wooded perennial shrub; can behave as an annual in cooler climates.
What fertiliser indian mallow actually wants — and why
Indian Mallow is a soft, fast leafy herb that you harvest hard — a modest balanced feed keeps tender growth coming without tipping it into bland or bolting.
A balanced general feed (even N-P-K) at modest strength — enough nitrogen to keep replacing the leaves you pick, but not so much that flavour thins or it bolts to seed.
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 indian mallow: 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 indian mallow, 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 indian mallow:
Apply a balanced slow-release granular fertiliser in spring; supplement with a dilute liquid feed every 4 weeks during the growing season to sustain flowering. In practice: a balanced liquid feed every few weeks through the main growing and harvesting season (spring through early autumn), more often the harder you are picking it.
The dormant-season rule matters more than the exact interval: skip feeding entirely when indian mallow 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 indian mallow
Half strength is a sensible default for indian mallow — enough to fuel regrowth after cutting, gentle enough that the leaves stay aromatic rather than watery.
Feeding always goes onto already-damp soil, never dry roots — water indian mallow first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the indian mallow watering schedule.
Signs you are over-feeding indian mallow
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for indian mallow:
- Fast, soft, pale growth with diluted, less aromatic flavour.
- Early bolting (running to flower) and a bitter edge.
- Salt crust and scorched tips on container plants.
Signs you are under-feeding indian mallow
- Pale, slow regrowth after cutting and small leaves.
- A tired, stalled plant that cannot keep up with harvesting.
- Yellowing older leaves in a long-spent pot.
If the symptoms point at watering, light or roots rather than nutrition, the full indian mallow care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Pot-grown indian mallow builds up feed salts quickly — water until it drains each time and flush the pot with plain water every few weeks, especially on a sunny windowsill.
Organic vs synthetic feeds for indian mallow
Organic options
A diluted seaweed feed or worm-casting tea keeps soft growth coming without overdoing it. UK: dilute seaweed or Westland; US: Espoma Garden-tone or Neptune's Harvest. Gentle, hard to overdo, flavour-friendly.
Synthetic / liquid feeds
A balanced liquid feed at half strength through harvesting — UK: Phostrogen, Baby Bio or Westland; US: Miracle-Gro all-purpose at half strength. Fast regrowth; just do not overdo the nitrogen.
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 indian mallow look like?
Fast, soft, pale growth with diluted, less aromatic flavour. Early bolting (running to flower) and a bitter edge. Salt crust and scorched tips on container plants. Over-feeding indian mallow with strong nitrogen is the usual mistake — it grows fast and lush but the leaves turn bland and it bolts to flower sooner, ending the useful harvest early.
Should I flush the soil of indian mallow?
