Anthurium

Anthurium andraeanum grows best in moist, well-draining soil. Water when the top inch of soil is dry, and avoid overwatering or root rot may occur. Ensure that the water can properly drain away; water-logged soil can be dangerous to the roots of the plant. Drench plants thoroughly and then allow the soil to dry out before water again.

Anthurium andraeanum plants prefer medium to bright light, but not direct sunlight as it can damage and fade the foliage. Plants grown in too low of light with become weak and spindly due to a lack of energy created by the light. Leaves have an iridescent sheen to them when the light is at the right intensity.

Anthurium andraeanum grows best in temperatures between 60-90 °F (16-32 °C). Make sure to keep plants away from drafts, away from cold or hot air vents, and from cold windows in the winter. Plants in colder temperatures may be susceptible to frostbite.

Anthurium andraeanum enjoys humid conditions and higher humidity will produce brighter colors in the foliage. It is best to mist the foliage every day or keep the plant in a humidity tray to help raise the humidity around it. A gentle draft from a fan can also help to enhance the humidity around the plant.

Anthurium andraeanum grows best in a loose, well-draining potting mix with a pH range of 5.5-6.5. The mix should contain a combination of equal parts perlite, vermiculite, and peatmoss to retain moisture while allowing for proper drainage. Adding some elecidated charcoal can improve the aeration of the mix and help with drainage.

Anthurium andraeanum should be fertilized during the growing season (spring to fall) with a balanced liquid fertilizer every two weeks. Avoid fertilizing during the winter as plants tend to be in a dormant stage and fertilizer can stress it out. Also, make sure not to over fertilize as this can lead to the plant being burned or damaged. Use a diluted fertilizer for the best results.

Anthurium andraeanum can be prone to pests like mealybugs and spider mites. Keeping the plant in a clean environment and removing possible hiding places can help prevent these pesky critters from infesting your plant. If you spot any bugs, you should quickly remove them from the plant by using a cotton swab dipped in rubbing alcohol. To deter these pests, you can also spray neem oil every few weeks.

Anthurium andraeanum should be repotted every two or three years, or perhaps even every year depending on its size. If the plant is rootbound or has yellowing leaves, it may be time to repot. When re-potting, make sure to use a well-draining potting mix and water thoroughly after potting. Avoid stagnant water at the base of the plant for best results.

Anthurium andraeanum doesn’t require intense pruning. However, you can remove any dead or damaged leaves to keep the plant looking its best. You can also remove any flower spathes or any old leaves that have lost their sheen to keep the plant looking healthy and attractive. If the plant appears leggy, you can trim it back to encourage richness and fullness.

Mulching can be beneficial for Anthurium andraeanum. Adding a layer of mulch around the roots of the plant can help conserve moisture and regulate the temperature of the soil. It can also prevent weeds from getting to the plant, and can help reduce diseases. Organic mulches like rotten leaves, bark, and bark chips are best.

Anthurium andraeanum can be propagated through division of existing clumps, stem cuttings, and air layering. Stem cuttings can be cut below a node, the point at which the leaves and flowers emerge from the stem. Make sure that the cutting is at least 5-6 inches and has two or three leaves. Dip the end of the cutting into a rooting powder and place it in a well-draining potting mix. Keep the pot in a warm, humid environment and water lightly. Air layering can also be used to propagate anthuriums. The most popular areas to layer the plant are the mid-section of the stem and the collar line. Make an incision at the collar line or stem, apply a rooting hormone to the incision, and wrap the area with moist moss and a plastic bag. The roots should form within 2-3 weeks.

Growing anthuriums in containers often needs a support stake or stake ties to keep the stem from toppling over. You can use bamboo stakes or trellis supports to provide added stability and upright growth. Ensure that the stem is well tied with the support to avoid damaging the stems.

Anthurium andraeanum doesn't require a dormant period but they typically need rest after the growing season in the winter. During this time, reduce the amount of water given to the plant as the roots may start to rot if overwatered. Also, do not fertilize the plant during the dormant period to avoid further stressing the plant.

Anthurium andraeanum can be toxic to pets. The plant contains small amounts of calcium oxalate which can cause mild stomach upset and drooling in animals. If ingested, contact your vet immediately.
