Adored for their striking heart-shaped white-veined leaves, the Anthurium Clarinervium is a must-have for every plant lover. It can be pretty frustrating when their incredible foliage starts to turn brown so we have put together a detailed guide to help you diagnose the issue, solve whatever is wrong and prevent it from happening again.
Lack of humidity can cause brown leaf tips
Dry air might be the cause of your Anthurium Clarinerviums’s brown leaves if the tips and edges are the first to go brown. Although the current brown tips are irreversible, there are quite a few simple ways you can increase the humidity to stop any more from developing on your plant.
Misting the leaves
This is the first port of call when it comes to increasing the humidity for your Anthurium Clarinervium and preventing brown leaves. Mist the leaves using a spray bottle 3-4 times a week. Not only will this increase the humidity but it will also get rid of any dust that has formed on the leaves so it’s a win-win. We recommend misting your Anthurium Clarinervium in the mornings as it allows enough time for the water droplets to evaporate before it gets cold during the night. Cold damp leaves are more susceptible to root rot so you want to be careful not to cause any other issues whilst trying to fix the brown leaves.
Put your Anthurium Clarinervium in the shower
Washing down your plant you can instantly increase the humidity and prevent more brown leaves. Put your plant in the bath or sink and wash down the leaves. Use lukewarm water at low pressure so you don’t damage, shock or burn your Anthurium Clarinervium.
Make a pebble tray
This method requires a little bit of DIY but it’s worth it in the end and is a good preventative measure for brown leaves on Anthurium Clarinerviums. Fill a tray with small stones and add water so it reaches about halfway up the tray. Place your Anthurium Clarinerviums on top and throughout the day the water will evaporate around the plant. You need to make sure that the roots of your plant are not touching the water (which is why it’s important to only fill up the tray halfway). If the roots are sitting in the water then it will very quickly lead to root rot and a whole host of other more serious issues, not just brown leaves.
Invest in a humidifier
These portable and affordable gadgets are a real game-changer when it comes to increasing the humidity for your plants and your Anthurium Clarinerviums (and your other humidity loving houseplants) will love you for it.
We recommend this humidifier from Amazon. We’ve been using it for years and our plants really love it!
Underwatering can also cause brown leaves
If the leaves on your Anthurium Clarinerviums have turned light brown, dry and crispy, then you may not be watering your plant enough. Although Anthurium Clarinerviumss like their soil to dry out between waterings, they won’t be able to go weeks and weeks without any water. Consistent underwatering will cause them to develop brown leaves.
Before you go and drown your Anthurium Clarinervium in water to prevent more brown leaves and make up for a lack of water, you need to make sure that this is actually the issue. Carefully take your Anthurium Clarinerviums out of the pot to inspect the soil. If it is very dry and powdery, and the roots are shrivelled, then your Anthurium Clarinervium will need more water.
Slowly reintroduce water to your plant over the course of a week as a sudden change in environment can shock your Anthurium Clarinerviums and cause more problems than a few brown leaves.
Check for temperature extremes
Your Anthurium Clarinerviums could be in an area where it is suffering from temperature shock without you feeling it and this might be causing the brown leaves. This often occurs if your Anthurium Clarinervium is too close to a heating/AC vent or a radiator. Whilst the overall temperature in your home might be ideal for cacti growth, be wary of drafty windows, doors and vents that might be affecting your Anthurium Clarinerviums.
Make sure to open your windows to make sure that the air in your home is circulating properly. This reduces the risk of hotspots forming in the room where your Anthurium Clarinerviums and will help to prevent brown leaves. You can always pick up a digital thermometer to check the spot your Anthurium Clarinerviums is sat for peace of mind.
Now that you’ve hopefully diagnosed the issue with your Anthurium Clarinervium you might be wondering what to do about the brown leaves that are already there. Unfortunately, once a leaf has turned brown, there is no reversing that. This is why we often recommend removing the leaves that have turned a solid brown colour.
If only the edges of the leaves have turned brown, then it can be a good idea to leave these as they aren’t all dead and can still be valuable to your Anthurium Clarinervium. However, any leaves that are fully brown and have crisped up should be removed. This will stop your plant from wasting energy trying to revive them. Instead, it allows your Anthurium Clarinervium to focus all of its energy on new healthy growth.
When removing the leaves, make sure to trim them off using sharp tools. Never rip or pull the leaves off by hand as this can damage the stems and other parts of the plant that might be otherwise healthy.
The key to preventing your Anthurium Clarinervium from developing brown leaves is to make sure that it is growing in the ideal environment. You need to make sure that environmental factors such as sunlight, warmth and humidity are right for your plant, as well as balance watering so that your Anthurium Clarinervium is getting what it needs.
Care requirements will be different for each plant so we recommend looking at our care guide for a more comprehensive overview.
