Overview
Madagascar Lace (Aponogeton madagascariensis) is a stunning specimen plant whose leaves are a natural lattice of holes. It is a advanced plant to grow, and rewards a bit of experience and good light with a lovely display.
This guide explains, in plain language, how to grow Madagascar Lace well: what it looks like, how much light it wants, whether it needs CO2, how to plant and place it, how to make more of it for free, and the simple mistakes to avoid.
Appearance & Growth
A stunning specimen plant whose leaves are a natural lattice of holes.
It is a medium grower and is normally used in the midground/background of the aquarium. Because it grows slowly, it stays tidy and needs little trimming, though slow leaves can gather algae if the light is very strong.
Lighting
Madagascar Lace does best under medium light. It wants bright, even light reaching its leaves, so use a good planted-tank LED.
Keep the lights on a timer for about 6 to 8 hours a day. Leaving lights on longer usually grows more algae, not more plant, so add light time slowly and watch for any green film.
CO2 & Fertilising
CO2: Optional. CO2 is optional - it speeds things up but is not essential.
Feed it with an all-in-one liquid fertiliser (such as API Leaf Zone) added to the water each week, and push a root tab into the substrate near the roots, as this is a hungry root-feeder. If leaves turn yellow, get holes, or stop growing, that is almost always a lack of nutrients, not a disease.
Planting & Placement
Place the bulb on top of the substrate or only half-buried - burying the whole bulb makes it rot. Once it sprouts, the roots anchor it. Give it room as it can grow large.
How to Propagate (Make More)
It grows from a bulb. Rest the bulb on the substrate or half-bury it (never fully) and it will sprout. Mature plants may grow side bulbs or flower.
Swapping cuttings is one of the best parts of the hobby - over time a single healthy plant can fill your tank and stock a few more.
Common Problems & How to Fix Them
The most common problem is algae growing on the leaves. This usually means too much light, not enough nutrients, or weak water flow - not a problem with the plant. Lower the light a little, add fertiliser, and improve flow.
Some leaf loss right after planting is normal while the plant gets used to living underwater - keep your light, CO2 and fertiliser steady and new growth will follow. Always remove dead or rotting leaves quickly to keep the plant and water healthy.
Is Madagascar Lace Right for Your Tank?
Madagascar Lace is a beautiful plant for keepers who can give it good light, well worth the small extra effort. Pair it with our other plant and aquascaping guides to build a lush, healthy planted tank.
