Botanical name: Anthurium andraeanum
Laceleaf prefers bright indirect light. A curtain-filtered sunny window is perfect. Protect the plant from direct sunlight to avoid scorching of the leaves. Learn more on how to ensure your plant receives the correct light in this guide on understanding light for houseplants.
Keep soil moist at all times for Laceleaf during the growing season but reduce watering in the cold season to maintain the soil slightly moist. Avoid waterlogging as it may lead to the root-rot. Learn more on how to water houseplants.
Average warmth with a minimum of 150C is ideal for Laceleaf. Protect it from cold draughts. Find out more on temperature for houseplants.
Laceleaf requires high humidity. Raise humidity by more frequent misting or set the pot on a wet pebble tray. Clean the leaves by damp-wiping with a soft cloth to get rid of dust and avoid water drops on the leaves as it may cause fungal infection.
Feed Laceleaf every 2-3 weeks during the growing period with a phosphorous-rich water-soluble fertilizer. Withhold feeding in the cold season as growth is minimal and feeding at this time can lead to fertilizer burn. Regularly flush out accumulated salts in the soil by running a stream of water through the soil until the water comes out through the drainage hole. Allow it to run for a few minutes and repeat several times. Learn more on how to feed houseplants.
Repot Laceleaf every 2 years at the beginning of the growing season. Use a pot one-size larger and free-draining soil that is rich in organic matter. Ensure the pot has drainage holes to prevent waterlogging.
Pruning Laceleaf is easy. Remove yellow and dead leaves to maintain the plant neat and tidy. Cut the leaves at the base of the stem. Wayward leaves can also be removed to maintain the shape of the plant. Learn more on how to prune houseplants.
Laceleaf can be propagated during the growing season from from splits. Divide the mother plant into several sections while ensuring each divison has some roots. Pot up the splits in moist soil in individual pots. Place the set up in a cool place and maintain the soil moist until new growth emerges. Ensure the crown of the plant is above the soil level to avoid rotting. Allow the plant to be well established before transplanting.
After blooming, give Laceleaf a 6 weeks rest period in a cool dimly-lit room at 150C. Give it very little water during this period. Bring it out after the rest period and continue with normal care. This will break the dormancy cycle and signal the plant to start blooming.
One reason for this is that the air is too dry for Laceleaf; set the pot on a wet pebble tray to raise humidity. The other reason for brown leaf tips is waterlogging of the soil; maintain the soil moist but not soggy.
There are two causes of yellow leaves in Laceleaf. One reason is waterlogging; maintain the soil moist but not soggy, ensure the pot has a drainage hole and the soil is free-draining. Reason number two is cold draughts; protect the Laceleaf from cold draughts or place it away from windy doors and windows.
These are sunburn marks caused by exposure of Laceleaf to direct sunlight. Move the plant to a shaded place or use a curtain to filter the light.
There are four causes of this in Laceleaf. One reason is low humidity: raise humidity by setting the pot on a wet pebble tray. Reason number two is incorrect watering, either underwatering or overwatering; maintain the soil moist at all times during the growing season and never allow the soil ball to dry out. Learn more on how to water houseplants. The third reason is too high temperature due to exposure to direct sunlight; protect the plant from direct sunlight. The fourth and last reason is pests and diseases infestation; take control measures for these pests.
Laceleaf that is not getting enough light will not bloom. Ensure the plant is receiving bright light but away from direct sunlight. Also underfeeding will prevent production of blooms. Feed Laceleaf every 2 weeks with a phosphorous-rich water-soluble fertilizer during the growing season.
If the Laceleaf was in bloom when you bought it, the reason could be it was forced to bloom before it was ready to bloom so it loses color as it ages. Improper watering, excess nitrogen fertilizer and wrong temperatures can also cause greening of the flowers. The blooms last for about 4 weeks and as they age, they begin to lose color by becoming green and paler as aging continues. Some species of Anthuriums produce blooms that turn brilliant green in color; check the species you are growing.
Laceleaf is prone to Root-rot Disease which is more prevalent in waterlogged soil.
Laceleaf (Anthurium andraeanum) is toxic to both humans and pets. It contains oxalate crystals which can cause digestive distress, breathing problems and skin irritation. Always wear gloves when handling and wash your hands thereafter.
