Brown leaves may indicate your plant isn’t getting enough of the minerals it requires. Anthuriums require nutrients like nitrogen, phosphorus, and potassium to grow.
Many anthurium growers use controlled-release fertilizers to prevent this issue, but if your leaves have already turned brown, you might wish to use a liquid fertilizer for a few weeks until your plant recovers. Just remember to dilute the liquid fertilizer to 25% of the advised strength.
Natural Aging of your Anthurium
How long have you had your plant? The leaves might simply be aging naturally! Old growth will naturally wither and drop to make way for newer growth, especially near the bottom of the plant. Sharp shears should be used to remove wilting, yellowing, or browning leaves or blossoms so that the plant may focus its efforts on maintaining healthy growth.
Leaf blight is the rapid browning and yellowing of your anthurium leaves. Your plant is probably experiencing one of the problems listed below if it is deteriorating quickly and all over.
Your Anthurium is Suffering from Sunburn
However, direct sunlight will cause your leaves to quickly dry out and kill the plant. The more light the plant receives, the more flowers it will produce. Your Anthurium should be placed in an area with strong indirect light.
Nutrient Deficiency for your Anthurium
After being depleted from your potting soil, your anthurium may not be receiving adequate nutrients including nitrogen, phosphate, and potassium. Until your plant starts to recover, we advise using a controlled release fertilizer at only 1/4 the amount specified on the package.
Overwatering Leading to Root Rot
If persistently overwatered, tropical plants like anthurium are very prone to developing root rot. During the growing season, which runs from March through September, keep the soil just barely damp. After giving your Anthurium adequate water, wait until the top 25 to 50 percent of the soil has dried up before giving it more.
You should remove your plant from the pot if its health is fast declining so you can check for root rot. Trimming back the rot and repotting your anthurium are the only ways to aid in the recovery of your plant if the roots are slimy or black.
Save your Anthurium by Repotting
You must repot your anthurium in order to save it. You have to use fresh potting soil that drains nicely. To repot your plant, follow these instructions:
- Select a pot with drainage holes that is about 2 bigger than the existing pot.
- Your new potting mix should be placed in the new pot up to a third of the way.
- Slide your anthurium out of the pot slowly. Cut off any roots that appear to be dead or mushy using sharp shears.
- Then, add the leftover potting soil to the new container, flatten it down, and set the anthurium within.
- After giving the plant a good soak until the water runs out the bottom, give it some time to dry out.
How does an overwatered anthurium appear?
Root rot can occur if your Anthurium is overwatered. How does that appear? The stems will become brown, and the roots will be mushy. Issues with soil quality or watering frequency could be the cause of this.
How are brown stains on anthurium leaves treated?
Why are the leaves on my anthurium going brown? Overexposure to sunshine, a lack of nutrients, or insufficient hydration can all result in brown leaves. Put your plant in bright indirect light—never in the sun—feed it once a month when it is actively growing with a high-phosphorus fertilizer, and water it once a week with six ice cubes or a half cup of water.
How frequently should anthuriums be watered indoors? Anthurium houseplants need only receive one weekly watering, with a brief period of soil drying in between. Six ice cubes placed immediately on the soil and allowed to melt can prevent leaves from getting wet, which can result in bacterial disease. Alternatively, you can directly pour a half cup of water into the soil.
How can an anthurium plant be revived?
The best way to revive an anthurium plant
- Put your plant somewhere brighter, but away from direct sunshine.
- Only water it once every week.
- Give it some additional plant food.
- You can discover how to repot your plant in this article.
How frequently do I need to water my anthurium?
H2O and Humidity
Low to medium water requirements apply to this houseplant. In between waterings, let the soil to dry out. If you reside in a hot climate, water your lawn once every two to three days; if it rains frequently, water as needed. The anthurium needs appropriate drainage most of all.
How can I tell if my anthurium is in trouble?
Remember that it won’t be possible to revive your plant if it is fully dead. Your anthurium can be too far gone if ALL of the leaves and blooms are completely brown and crispy, or if ALL of the leaves have fallen off.
You can probably still salvage your anthurium if it is simply wilting or drooping or if the leaves have some brown patches on them. If you take care of issues as soon as they arise, you can repair problems including yellowing, losing leaves, and unblooming blooms.
Let’s examine some typical issues that lead to anthurium plant decline and how to resolve them to restore your plant.
Anthurium: Does it require sunlight?
Anthuriums are known for their enduring, heart-shaped blooms. The colorful, magnificent blossoms add a wonderful pop of color to the house and are quite simple to maintain!
If you have bright shade, anthuriums are a fantastic option for an outdoor summer container as they thrive in the heat and humidity and should bloom all season.
Light:
Anthuriums will grow and survive in low light, but they won’t blossom because they need medium to bright light to bloom. Select a location that receives some sunshine but is not directly in the sun (early morning or late afternoon sun is generally OK).
Water:
Keep the soil barely damp but not drenched. In the spring and summer, the plant will require extra water, especially if it is in direct sunlight. Root disease may result from overwatering and be challenging to treat.
Use any all-purpose fertilizer ideal for indoor plants to fertilize in the spring and summer. You can achieve excellent results by fertilizing at a diluted rate (often 1/4 strength) with each watering, and you won’t need to keep track of when you last fertilized. It also works well to use a slow-release fertilizer like Osmocote.
Heat Index and Humidity:
Regular home temperatures are excellent, but like many tropical houseplants, summertime outdoors brings additional heat and humidity that feels “exactly like home.” If you decide to grow your Anthurium outdoors, just be sure to keep it away of direct sunlight.
Do not place your Anthurium too close to a heat source or in a hot or cold draft. This may cause the leaves to dry out and develop brown tips.
Repotting:
Repot your Anthurium in the spring when the roots are starting to grow if it is outgrowing its container. Any high-quality, well-drained soil mixture will do.
Anthuriums develop an extended stem with exposed root nubs as they get older. These stems can be wrapped in wet sphagnum moss, tied, and covered with a thin piece of plastic to keep the moisture in. The roots should start to develop into the moss if you keep it moist. Once a significant number of new roots have grown, the stem can be severed at the soil line and the newly developed roots potted.
Anthuriums should continue to bloom for nearly the entire year as long as they receive enough light, moisture, and fertilizer during active growth. If your Anthurium isn’t blossoming, it’s probably due to a lack of moisture or light.
How can dead leaves be removed from an anthurium?
Regular anthurium trimming is necessary to maintain the plant’s balance and erect posture. The stem may bow if older growth is allowed to stay on the plant, which could lead to stunted growth. Here are some pointers for pruning anthuriums safely:
Examine your anthurium plant carefully, then start pruning from the top down. Eliminate any dead or discolored leaves. Cut wilted or dead flowers all the way to the stem’s base. To make the plant look better, you can also pluck stray leaves, but be sure to leave three to five. Remove elder leaves first, if you can.
Anthurium suckers should be removed from the plant’s base since they consume energy and shrink the size of the flowers. Trim the suckers when they are young since trimming huge suckers could harm the plant’s root system.
Use high-quality cutting tools to prevent the plant from being more vulnerable to disease and pests by tearing and crushing stems. Wipe cutting implements with rubbing alcohol or a 10% bleach solution after each cut to avoid bacterial contamination.
Note that anthurium includes poisonous substances for both people and animals. When trimming anthuriums, put on gloves to protect your hands from mild skin irritations brought on by the sap.
Does Miracle Grow benefit anthurium plants?
In a 5-8 inch (12.5-20 cm) pot, bury the top of the root ball 1 inch (2.5 cm) into the dirt. Use a potting soil that is light, permeable, and well-draining. Only repot anthurium plants when they have grown root-bound in a pot one size larger than the one they are now in.
Which soil mixture works best is a topic on which there are many different viewpoints in the gardening community. Perlite, peat moss, moisture control potting mix, and orchid potting mix seem to work best for anthuriums in my experience.
Why is my anthurium plant acting up?
The majority of Anthurium cultivars used for cut flowers are variations of the epiphytic plant endemic to Columbia and Ecuador, Anthurium andraeanum. Consumers can easily identify cultivars of Anthurium andraeanum by their distinctive huge red blossoms (Figure 1). Pink, orange, white, green, purple, and mixtures of these colors are some of the new flower colors that have been introduced through breeding.
The production of flowering potted Anthuriums is currently dominated by Florida. In order to produce potted plants, A. andraeanum has been crossed with dwarf species including A. amnicola and A. antioquiense. The University of Florida Plant Breeding Program has introduced three compact, hybrid types of potted Anthurium: “Red Hot” (Henny, Chen, and Mellich 2008a), “Orange Hot” (Figure 2) (Henny, Chen, and Mellich 2008b), and “Southern Blush” (Henny, Poole, and Conover 1988).
Since anthurium is highly vulnerable to bacterial and fungal infections, commercial output may be significantly hampered. The most dangerous bacterial blight is probably that brought on by Xanthomonas. In the cultivation of anthurium, root rots brought on by Rhizoctonia, Pythium, and Phytophthora also occur. Therefore, being able to recognize and eradicate these diseases is crucial.
Do you use ice cubes to water anthuriums?
Overwatering is one of the most typical anthurium care errors. Our anthurium will thrive when the soil has a chance to partially dry out in between waterings. We advise watering with 6 ice cubes or 1/2 cup of water once a week. Root rot can result from excessive or frequent watering, which could have a negative impact on your plant’s long-term health.
If you accidentally overwater something, try removing any rotting roots and waiting until the soil is mostly dry before watering it again. If you discover root rot early, you might be able to recover. Also, remove extra water from the pot on a regular basis.
Can brown leaves revert to green?
Typically, underwatering, sunburn, or overwatering are the causes of browning leaves.
The soil possibly grew too dry for an extended period of time between waterings if the leaf tips are turning brown and hard. The plant may lose leaves as a result of this. This does not necessarily imply that you are regularly underwatering because the browning may have only occurred once. Although the brown leaf tips won’t turn green again, you can trim the brown margins to restore the plant’s healthy appearance. Go here to learn more.
It may also be a symptom of overwatering if you see brown patches all over the leaves. You’ll typically notice some yellowing of the leaves as well when the plant is overwatered. Go here to learn more.
If you see brown stains in the middle of the leaves, it may be because the leaves are receiving too much direct sunshine. Some plants are readily burned by direct sunlight and are sensitive to it. If this is the case, try shifting your plant to a spot where it won’t be exposed to the sun’s glare.
– If you move your plants from indoors to outdoors in the summer without acclimating them to direct sunshine, this is usually what happens.
