About Maranta 'Lemon Lime'

Maranta leuconeura 'Lemon Lime' · also called Lemon Lime Prayer Plant, Lemon Lime Maranta · houseplant

The Maranta 'Lemon Lime' is a compact prayer plant prized for neon-green leaves that fold upward at night. It thrives in bright indirect light, evenly moist soil with filtered water, and humidity above 50 percent. The ASPCA lists Maranta and the prayer plant group as non-toxic, making it a safe, pet-friendly houseplant.

Growth habit: Low-growing, clump-forming rhizomatous perennial with a spreading, slightly trailing habit. Exhibits nyctinasty — leaves fold upward like praying hands at night and relax open by day. Spreads outward rather than tall, making it well suited to shallow pots and hanging displays.

Watch for — Brown, crispy leaf tips and edges: Usually low humidity or mineral/salt build-up. This plant is sensitive to fluoride and chlorine — switch to filtered, distilled or rainwater and raise humidity above 50 percent.

What fertiliser maranta 'lemon lime' actually wants — and why

Maranta 'Lemon Lime' 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 maranta 'lemon lime': 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 maranta 'lemon lime', 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 maranta 'lemon lime':

Feed every 2-4 weeks during spring and summer with a balanced water-soluble houseplant fertiliser diluted to half strength. Stop or reduce to monthly in autumn and winter when growth slows. Over-fertilising, especially excess nitrogen, causes leaf-tip burn, so flush the soil occasionally to clear salt build-up. Treat that as every 2-4 weeks 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 maranta 'lemon lime' 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 maranta 'lemon lime'

Half strength is the safe default for maranta 'lemon lime' — 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 maranta 'lemon lime' first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the maranta 'lemon lime' watering schedule.

Signs you are over-feeding maranta 'lemon lime'

Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for maranta 'lemon lime':

Signs you are under-feeding maranta 'lemon lime'

If the symptoms point at watering, light or roots rather than nutrition, the full maranta 'lemon lime' care brief covers soil, humidity and the common problems for this species.

Flushing and leaching the salts

Flush the pot of maranta 'lemon lime' 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 maranta 'lemon lime'

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.

Half strength is the safe default for maranta 'lemon lime' — houseplant feeds are formulated strong, and the diluted dose is gentler on the roots while still ample for foliage.

What does over-feeding maranta 'lemon lime' 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 maranta 'lemon lime' 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 maranta 'lemon lime'?

Flush the pot of maranta 'lemon lime' 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.
